what are the properties of group 5 cations?
605984
Group 5 cations are magnesium (II) Mg2+, potassium (I) K+ and sodium (I) Na+. These cations do not react with hydrochloric acid HCl, hydrogen sulphide H2S, ammonium sulphide and ammonium carbonate (NH4)2CO3. Magnesium does show similar reactions to IVth group cations; it forms basic magnesium carbonate MgCO3.Mg(OH)2.

AB has ZnS structure (ccp structure). Hence, the minimum radius of the cation A+ will be 22.

As you can see, the manganese(II) cation has a total of 5 electrons in its 3d subshell, with one electron distributed in each of the five 3d orbitals.

Group 15: Nitrogen Group Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they vary in their reactivity.

The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they vary in their reactivity.

By far the most common ion of Group 13 metals is +3. So. the most common gallium ion is Ga3+ , and its electron configuration is [Ar]3d10 .

The alkaline earth metals in group 2 are always +2 when they form cations. Aluminum and the elements in group 3 are always +3 when they form cations. Zinc and cadmium always form +2 cations. Although silver can form both +1 and +2 cations, the +2 is so rare that we usually name Ag+ as silver ion, not silver(I) ion.

About the Group Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).

The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer shell. Similarly, the atoms of all group 7 elements have similar chemical properties and reactions to each other, because they all have seven electrons in their outer shell.
