Periodic Trends Review

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

Which element has a lower first ionization energy than Scandium (Sc)?

Back

Calcium (Ca) has a lower first ionization energy than Scandium.

Front

What is the trend in atomic radius across a period?

Back

Atomic radius decreases across a period from left to right due to increasing nuclear charge.

Front

What is the trend in atomic radius down a group?

Back

Atomic radius increases down a group due to the addition of electron shells.

Front

What does high electronegativity indicate about an atom?

Back

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

Front

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

Back

Carbon (C) has a higher electronegativity than arsenic.

Front

What is the trend of electronegativity across a period?

Back

Electronegativity increases across a period from left to right.

Front

What is the trend of electronegativity down a group?

Back

Electronegativity decreases down a group.

Front

Which of the following elements has the largest atomic radius: Lithium (Li), Sodium (Na), or Potassium (K)?

Back

Potassium (K) has the largest atomic radius.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, as ionization energy increases, electronegativity also increases.
