Metal ions do not share electrons with one another. Metal ions have a positive charge.
The H+ ion has no electrons.
Part of a metallically bonded substance.
A metal ion is a metal atom that has either lost or gained an electron (although most metals tend to lose electrons rather than gain them). Any atom that has lost or gained one or more electrons is called an ion. A metal ion is thus a metal atom with a charge. Some examples are Fe3+ (iron with a plus three charge, or that lost three electrons), Ag+ (silver ion with a plus one charge) and Cu2+ (copper with a plus 2 charge).
an atom, ion or molecule that can donate a pair of electrons to a metal ion
It's chromium. The element would have lost 2 electrons from the 4s subshell, leaving 3d4 as your valence.
This alkali metal is lithium (Li).
Yello. The color comes from the chromate ion which is yellow. The ion is colored as it contains a transition metal atom and has readily excitable electrons.
Sodium is a chemical element. Sodium chloride is NaCl but sodium is not a transition metal.
There are 10 electrons in an Mg2+ ion.
Metal ions do not share electrons with one another. Metal ions have a positive charge.
The element with 28 electrons is Nickel, Ni. However, various compounds can be isoelectronic with Ni and have 28 electrons, such as Zn2+.

O2- ion is known as peroxide in English. As it is not a transition metal ion, it is not able to be written any other way. If it were a transition metal such as Lead (Pb), the Pb4+ ion can be called lead (IV) or plumbic. Lead (IV) is written in the Stock method with roman numerals representing the electrons in the ion. Plumbic is written in the Classical method with the suffixes "ic" and "ous". As some transition metals have two different ions, "ic" is added to the higher ion name while "ous" is added to the lower ion name.
The H+ ion has no electrons.
The subscript of the second ion identifies the oxidation state of the transition metal
