Periodic Trends

Front

As you move across the periodic table, atoms tend to get smaller because:

Back

The atoms have more protons.

Front

Which element has a higher electronegativity than arsenic (As)?

Back

Carbon (C)

Front

Why does chlorine (Cl) have the highest electronegativity in Period 2?

Back

Cl is the smallest and has the greatest effective nuclear charge.

Front

What term describes an atom's tendency to attract electrons when chemically combined with another element?

Back

Electronegativity.

Front

Which periodic group has the smallest atomic radius?

Back

Noble Gases.

Front

What is the trend in atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases.

Front

What is the trend in ionization energy as you move across a period from left to right?

Back

Ionization energy increases.

Front

What is the trend in electronegativity as you move down a group in the periodic table?

Back

Electronegativity decreases.

Front

What is the effective nuclear charge?

Back

The net positive charge experienced by an electron in a multi-electron atom.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.
