A cation is formed by the loss of an electron from the valence shell of an atom.
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
Metals are more likely to donate electrons to form ionic compounds. However, some transition metals such as mercury and tin can form covalent bonds in which the metal shares an electron with another atom
cation is positively charged ion. metals lose electrons to form cations.
metals have high electropositivity and low ionisation energy. So they tend to form cations easily.
most transition metals form ions with a 2+ charge.

Take the alkali earth metals as an example, column I in the Periodic Table. All of them have an unpaired s electron in their outer shell. All of them will form a +1 cation. When you go down the column, all of them will have a similar outer shell configuration. The transition metals are different, however.
Any metals in the reference table can form an ionic bond with a Br atom.For example, Lithium, Sodium and Calcium.
An element's number of protons can predict whether it will form a cation or anion. It will form a cation if it has more protons than electrons, or an anion if there are more electrons than protons.
