Periodic Trends

Front

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

Back

Atomic radius generally increases as you move down a group due to the addition of electron shells.

Front

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

Back

Atomic radius generally decreases as you move from left to right across a period due to increased nuclear charge pulling electrons closer.

Front

Define electronegativity.

Back

Electronegativity is a measure of how well an atom can attract and hold onto electrons.

Front

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

Back

Electronegativity increases from left to right across a period.

Front

What happens to electronegativity as you move down a group?

Back

Electronegativity decreases as you move down a group.

Front

Which element has a larger atomic radius: Magnesium or Strontium?

Back

Strontium has a larger atomic radius than Magnesium.

Front

What is the relationship between atomic radius and electronegativity?

Back

Generally, as atomic radius increases, electronegativity decreases.

Front

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

Back

Ionization energy generally increases as you move from left to right across a period.

Front

What is the trend of ionization energy as you move down a group?

Back

Ionization energy generally decreases as you move down a group.

Front

What is the significance of the octet rule in relation to electronegativity?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell, influencing their electronegativity.
