Question

Choose the statement that is TRUE. Question 26 options: Outer electrons efficiently shield one another from nuclear charge. All of the answers are true Valence electrons are most difficult of all electrons to remove. Core electrons effectively shield outer electrons from nuclear charge. Core electrons are the easiest of all electrons to remove.

Answer 1

The statement which is true is Core electrons effectively shield outer

electrons from nuclear charge.

Core electrons are those which are in close proximity with the nucleus.  The

core electrons repel the outer electrons farther away from the nucleus to

shield it from nuclear charge.

The valence electrons are usually found in the outermost part of the shell

and they are the easiest to remove due to the fact that they have to achieve

a stable octet configuration which makes them easily removed during

chemical reactions.
