Front

What happens to atomic radius as you move from left to right across a period?

Back

Atomic radius decreases as you move from left to right across a period due to increasing nuclear charge.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

How does electronegativity change across a period?

Back

Electronegativity generally increases as you move from left to right across a period.
