Atomic orbitals are typically categorized by n, l, and m quantum numbers, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively.

Atomic orbitals are the basic building blocks of the atomic orbital model ( alternatively known as the electron cloud or wave mechanics model ), a modern framework for visualizing the microscopic behavior of electrons in matter.

Atomic orbitals can be the hydrogen-like " orbitals " which are exact solutions to the Schrödinger equation for a hydrogen-like " atom " ( i. e., an atom with one electron ).

Atomic physics underlies the workings of chemistry, which studies emergent properties that in turn are the basis of biology.

" Atomic " data, that is, data at the lowest level of detail, are stored in the data warehouse.

Atomic properties like the ionization energy are often quoted in electron volts.

According to the International Atomic Energy Agency there are at least 100 research reactors in the world fueled by highly enriched ( weapons-grade / 90 % enrichment uranium ).

Professor John Mueller of Ohio State University, the author of Atomic Obsession, has also dismissed the need to interfere with Iran's nuclear program and expressed that arms control measures are counterproductive.

Atomic absorption lines are observed in the solar spectrum and referred to as Fraunhofer lines after their discoverer.

A summary of the amounts of radioactive wastes and management approaches for most developed countries are presented and reviewed periodically as part of the International Atomic Energy Agency ( IAEA ) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

The Atomic orbital | orbitals of the hydrogen atom are descriptions of the probability distribution s of an electron bound state | bound to a proton.

International Atomic Time ( TAI ) is the primary international time standard from which other time standards, including UTC, are calculated.

; Atomic operations: Shared data are accessed by using atomic operations which cannot be interrupted by other threads.

Atomic bombs are based on the theory of nuclear fission, that when a large atom splits it releases a massive amount of energy.

Atomic models will consist of a single nucleus that may be surrounded by one or more bound electrons, whilst molecular models are typically concerned with Molecular Hydrogen and it's Molecular hydrogen ion.

Its Atomic number and atomic symbol are unknown.

The remaining bomb casings are located at the Russian Atomic Weapon Museum, Sarov ( Arzamas-16 ), and the Museum of Nuclear Weapons, All-Russian Research Institute of Technical Physics, Snezhinsk ( Chelyabinsk-70 ).

In various forms, other designs are under development by MIT, University of California at Berkeley, General Atomics ( U. S .), the Dutch company Romawa B. V., Adams Atomic Engines, and Idaho National Laboratory.

These are funded by various national agencies like the Department of Science and Technology, Department of Electronics, Department of Space, Aeronautical Development Agency, Department of Atomic Energy, and Oil and Natural Gas Commission ( ONGC ).

Atomic units are often abbreviated " a. u.

* 1985-1990 in the Film series Back to The Future, references to the Atomic Age and uses of Nuclear Energy are broadly explored ; for example the use of Plutonium in the time machine, the concept of " Mr. Fusion " ( a futuristic small scale fusion reactor for domestic use that can use garbage as fuel ) and references to the common 1950s conceptions of the Atomic Age.

There have also been numerous clones made ( and are still being made ) such as Atomic Tanks, Nasty Armoured Tanks of War, xscorch ( Open Source clone ), Scorched 3D, which attempt to modernize the gameplay and graphics, and others such as Charred Dirt that take a different approach by using a unique graphical style.

The SI second was defined in terms of the caesium atom in 1967, and in 1971 it was renamed International Atomic Time ( TAI ).

Atomic orbitals may be defined more precisely in formal quantum mechanical language.

More precisely, it was defined that TT instant 1977-01-01T00: 00: 32. 184 exactly and TCG instant 1977-01-01T00: 00: 32. 184 exactly correspond to the International Atomic Time ( TAI ) instant 1977-01-01T00: 00: 00. 000 exactly.

TDT is tied in its rate to the SI second, as is International Atomic Time ( TAI ), but because TAI was somewhat arbitrarily defined at its inception in 1958 to be initially equal to a refined version of UT, TT is offset from TAI, by a constant 32. 184 seconds.

These stages, as defined by founder Eugene Rabinowitch in " The Atomic Age " were Failure, Peril, and Fear.

The term is not officially defined by the International Atomic Energy Agency or by the U. S. Nuclear Regulatory Commission.

A nuclear and radiation accident is defined by the International Atomic Energy Agency as " an event that has led to significant consequences to people, the environment or the facility.

In these artificial languages an Atomic Sentence is a string of symbols which can represent an elementary sentence in a natural language, and it can be defined as follows.

Although the best model adds a quadratic term to defined International Atomic Time, the team encountered problems with this theory.

Atomic values may belong to any of the 19 primitive types defined in the XML Schema specification ( for example, string, boolean, double, float, decimal, dateTime, QName, and so on ).

The Mars Sol Date is defined mathematically as MSD = ( Julian Date using International Atomic Time-2451549. 5 + k )/ 1. 02749125 + 44796. 0, where k is a small correction of approximately 0. 00014 d ( or 12 s ) due to uncertainty in the exact geographical position of the prime meridian at Airy-0 crater.

However, by August 1, 1946, when the Atomic Energy Act reached President Truman for signature, the second purpose was revised to state, “( 2 ) A program for the control of scientific and technical information ...,” and Section 9 was removed and replaced by a new Section 10, “ Control of Information .” This new section contained the novel doctrine later described as “ born secret ” or “ classified at birth .” It defined a new legal term, “ restricted data ”, as “ all data concerning the manufacture or utilization of atomic weapons, the production of fissionable material, or the use of fissionable material in the production of power ,” unless the information has been declassified.

DOE officials, first in phone calls and then in person, attempted to dissuade The Progressive from publishing the article on the grounds that it contained " secret restricted data " as defined by the Atomic Energy Act.

Different countries may use different terminology: in the United States of America, " nuclear material " most commonly refers to " special nuclear materials " ( SNM ), with the potential to be made into nuclear weapons as defined in the Atomic Energy Act of 1954.

* 1967 – The European Community is formally created out of a merger with the Common Market, the European Coal and Steel Community, and the European Atomic Energy Commission.

In a section of the Quebec Agreement formally entitled " Articles of Agreement governing collaboration between the authorities of the USA and UK in the matter of Tube Alloys ", Britain and the USA agreed to share resources " to bring the Tube Alloys the Atomic Bomb project to fruition at the earliest moment.

In 1948, Saha was formally asked by the Government of India at Nehru's insistence about the formation of Atomic Energy Commission which Bhabha had suggested.

In a section of the Quebec Agreement formally entitled " Articles of Agreement governing collaboration between the authorities of the USA and UK in the matter of Tube Alloys ", the United Kingdom and the United States agreed to share resources " to bring the Tube Alloys the Atomic Bomb project to fruition at the earliest moment.

Ames Laboratory was formally established in 1947 by the United States Atomic Energy Commission as a result of the Ames Project's successful development of the most efficient process, the Ames Process, to produce high-purity uranium metal in large quantities for the Manhattan Project.

The following includes a number of events prior to the official formation of the Manhattan Project as the Manhattan Engineering District ( MED ) in August 1942 and a number of events after the atomic bombings of Hiroshima and Nagasaki, until the MED was formally replaced by the United States Atomic Energy Commission in 1947.
