2 answers:
Explanation:
Aqueous solution of copper (II) bromide when reacts with aqueous solution of lead (II) acetate then it results in the formation of an insoluble solid of lead bromide and an aqueous solution of copper acetate.
The chemical reaction equation will be as follows.
This reaction is basically a double displacement reaction.

Answer: alkaline earth metals (group-IIA)
Explanation:
The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.
Alkaline earth metals donate 2 valence electrons to acquire noble gas configuration.
For example: Berrylium is the first alkaline earth metal with atomic number of 4 and thus has 4 electrons
Electronic configuration of berrylium:
Berrylium atom will loose two electrons to gain noble gas configuration and form berrylium cation with +2 charge.
Thus Elements donate 2 electron to produce a cation with a 2+ charge are alkaline earth metals.
