Periodic Trends Assessment

Front

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

Back

The atomic radius increases as you move down a group due to the addition of energy levels for the electrons.

Front

What is the trend of atomic radius as you move from left to right across a period in the periodic table?

Back

The atomic radius decreases as you move from left to right across a period due to increased nuclear charge pulling electrons closer to the nucleus.

Front

Define electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons from another atom.

Front

Which element has a higher electronegativity: fluorine (F) or iodine (I)?

Back

Fluorine (F) has a higher electronegativity than iodine (I).

Front

What happens to ionization energy as you move down a group in the periodic table?

Back

Ionization energy decreases as you move down a group due to increased atomic size and shielding effect.

Front

What happens to ionization energy as you move from left to right across a period?

Back

Ionization energy increases as you move from left to right across a period due to increased nuclear charge.

Front

What is the relationship between atomic size and metallic character?

Back

As atomic size increases, metallic character increases.

Front

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

Back

Electronegativity decreases as you move down a group.

Front

What is the trend of electronegativity as you move from left to right across a period?

Back

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

Front

What is the effect of increased energy levels on atomic radius?

Back

Increased energy levels result in a larger atomic radius.
