An covalent compound can be described as (3.3pts) 0 the formation of ions by the gain of electrons. a theorectical concept not possible in the real world. 0 the formation of ions by the loss of electrons. a crystalline substance as a result of a large number of electrons transered from metal atoms to non-metal atoms. sharing of electrons between two or more atoms.

When an element forms an anion, what happens to the radius? When an element forms a cation, what happens to the radius? Why? Define the term isoelectronic. When comparing size of ions. Which ion has the largest radius and which ion has the smallest radius in an isoelectronic series? Why?

Why do nonmetals tend to form anions rather than cations?
