Front

What is electronegativity?

Back

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

Front

How does electronegativity change across a period in the periodic table?

Back

Electronegativity increases from left to right across a period.

Front

How does electronegativity change down a group in the periodic table?

Back

Electronegativity decreases from top to bottom within a group.

Front

Which element has a higher electronegativity: Cl or Al?

Back

Cl has a higher electronegativity than Al.

Front

What is the element with the largest electronegativity in the halogens?

Back

Fluorine (F) has the largest electronegativity among the halogens.

Front

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

Back

Atomic numbers increase as you move from left to right across a period.

Front

What is the trend in atomic size as you move down the periodic table?

Back

Atoms get larger as you move down the periodic table.

Front

Why do atoms get larger as you move down the periodic table?

Back

Atoms get larger because they have more energy levels.

Front
