PERIODIC TRENDS

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

How does ionization energy change across a period?

Back

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

Front

What is the trend of ionization energy down a group?

Back

Ionization energy decreases down a group because the outer electrons are further from the nucleus and experience more shielding.

Front

Which element commonly forms a 3+ ion?

Back

Aluminum (Al) commonly forms a 3+ ion.

Front

What is the most common charge for group 13 elements?

Back

The most common charge for group 13 elements is 3+.

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?

Back

Electronegativity increases from left to right across a period.

Front

Which element has a greater electronegativity: N or C?

Back

Nitrogen (N) has a greater electronegativity than Carbon (C).

Front

What happens to atomic radius as you move down a group?

Back

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

Front

What is the reason for the increase in atomic radius down a group?

Back

The increase in atomic radius down a group is due to the addition of more shells (energy levels).
