Nickel is [Ar]4s23d8 and so has 10 valence electrons. It is usually valence 2 though.
NiS .simple just take H2S so s has valency 2.we know nickel has valency 2(i hope you did) so formula is NiS
The oxidation number of nickel in nickel nitrate is +2. In nickel nitrate, the nitrate ion has a charge of -1, and since the overall compound is neutral, the nickel ion must have an oxidation state of +2 to balance the charges.
The valency of lithium is 1. It has one valence electron in its outer shell.
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
Nickel mostly forms the +2 ions with several anions so its valency is +2. So the valency of nickel is 2
NiS .simple just take H2S so s has valency 2.we know nickel has valency 2(i hope you did) so formula is NiS
S = +6 valency O = -2 valency
The oxidation number of nickel in nickel nitrate is +2. In nickel nitrate, the nitrate ion has a charge of -1, and since the overall compound is neutral, the nickel ion must have an oxidation state of +2 to balance the charges.
The valency of lithium is 1. It has one valence electron in its outer shell.
Its valency is 0.
the valency is 4
magnesium has a valency of 2
the valency for nitrite is 5
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
