Back

Fluorine (F) is the most electronegative element.

Front

What trend is observed in electronegativity across a period?

Back

Electronegativity increases from left to right across a period.

Front

What trend is observed in electronegativity down a group?

Back

Electronegativity decreases as you move down a group in the periodic table.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.
