The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
The electron configuration of Cu2+ is [Ar]3d94s0.
Rust
because in aqueous state copper has minimum hydration enthalpy in an oxidation state of +2, so it is most stable in +2 oxidation state
Iron can exist in the body as ferrous or ferric, depending on what part of the biological process iron is in. For instance, iron in the plus two-oxidation state is "ferrous". Iron in the plus three-oxidation state is ferric.
assuming you mean sodium plus iron II carbonate, the products are iron plus sodium carbonate. iron is a transitional metal which can make +2 or +3 ions, and YOU need to state that in your word equation. there no such thing as iron carbonate, but there is such thing as iron II carbonate and iron III carbonate

The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
Iron plus chlorine equals Iron chloride is the word equation.
There is no elemental iron (Fe) involved in this reaction, neither as reactant (iron sulphide -FeS- plus oxygen are) nor as product (iron oxide (FeO) plus sulphur dioxide are)
There are 4 unpaired electrons in the ground state electron configuration of an Fe atom. These 4 unpaired electrons are in the 3d subshell.
i think so
FeSO4 Iron II Sulfate is one possibility
iron sulphate
Yes, Fe (iron) plus S (sulfur) equals FeS (iron sulfide). If the iron ion is iron(ll) then it is iron(ll) sulfide; if it is iron(lll), then it iron(lll) sulfide.
