An anion reaction with a metal and forms a -3 charge. How many atoms of the metal would be required if the element is in group 1 on the periodic table?

Sagot :

Answer:

3 atoms

Explanation:

The number of atoms of the metal that would be required as it forms an anionic charge of -3 is 3 atoms.

Elements in group 1 generally have a charge of +1. They have a valency of 1

By the virtue of this;

 It will take 3 atoms of a group one element to combine with an anion with a -3 charge on it.

This way, the ionic bond forms and the compound becomes neutral.
