What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Back

Carbon (C) has a higher electronegativity than arsenic.

Front

What is the common charge on an atom in group 17?

Back

The common charge on an atom in group 17 is -1.

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right within a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases from top to bottom within a group.

Front

Which atom has the largest atomic radius in Period 4?

Back

Potassium (K) has the largest atomic radius in Period 4.

Front

What does it mean for an atom to have high electronegativity?

Back

Atoms with high electronegativity hold on to their electrons more tightly.

Front

What is the trend of atomic radius as you move down a group?

Back

The atomic radius increases as you move down a group.

Front

What is the trend of atomic radius as you move across a period?

Back

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

Front

What is the relationship between atomic number and electronegativity?

Back

Generally, as atomic number increases, electronegativity increases across a period but decreases down a group.
