Front

What trend in electronegativity is observed across a period in the periodic table?

Back

Electronegativity increases across a period from left to right.

Front

What trend in atomic radius is observed down a group in the periodic table?

Back

Atomic radius increases down a group.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high electronegativity also have high ionization energy.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

How does the atomic radius change as you move from left to right across a period?

Back

The atomic radius decreases as you move from left to right across a period.
