Of sulfur nucleophiles, hydrogen sulfide and its salts, thiols ( RSH ), thiolate anions ( RS < sup >−</ sup >), anions of thiolcarboxylic acids ( RC ( O )- S < sup >−</ sup >), and anions of dithiocarbonates ( RO-C ( S )- S < sup >−</ sup >) and dithiocarbamates ( R < sub > 2 </ sub > N-C ( S )- S < sup >−</ sup >) are used most often.

then there are elements x and y in R such that ax + by = d. The reason: the ideal Ra + Rb is principal and indeed is equal to Rd.

Two ideals A and B in the commutative ring R are called coprime ( or comaximal ) if A + B = R. This generalizes Bézout's identity: with this definition, two principal ideals ( a ) and ( b ) in the ring of integers Z are coprime if and only if a and b are coprime.

The oxidation state + 3 originates from the 6d < sup > 1 </ sup > 7s < sup > 2 </ sup > electronic configuration of actinium, that is it easily donates 3 electrons assuming a stable closed-shell structure of the noble gas radon.

The oxidation state + 2 is only known for actinium dihydride ( AcH < sub > 2 </ sub >).

Several other oxidation states are known, which range from + 2 to + 7 and can be identified by their characteristic optical absorption spectra.

As an example, the field of real numbers is not algebraically closed, because the polynomial equation x < sup > 2 </ sup > + 1 = 0 has no solution in real numbers, even though all its coefficients ( 1 and 0 ) are real.

Also, no finite field F is algebraically closed, because if a < sub > 1 </ sub >, a < sub > 2 </ sub >, …, a < sub > n </ sub > are the elements of F, then the polynomial ( x − a < sub > 1 </ sub >)( x − a < sub > 2 </ sub >) ··· ( x − a < sub > n </ sub >) + 1

Below pH 2. 2, the predominant form will have a neutral carboxylic acid group and a positive α-ammonium ion ( net charge + 1 ), and above pH 9. 4, a negative carboxylate and neutral α-amino group ( net charge − 1 ).

In more general sense, each column is treated as a polynomial over GF ( 2 < sup > 8 </ sup >) and is then multiplied modulo x < sup > 4 </ sup >+ 1 with a fixed polynomial c ( x ) = 0x03 · x < sup > 3 </ sup > + x < sup > 2 </ sup > + x + 0x02.

The alpha particle also has a charge + 2, but the charge is usually not written in nuclear equations, which describe nuclear reactions without considering the electrons.
