Periodic Trends

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 in Group 16 as you move down the group?

Back

Electronegativity decreases as you move down Group 16.

Front

Which element in Period 3 has the lowest electronegativity?

Back

Sodium (Na) has the lowest electronegativity in Period 3.

Front

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

Back

Atomic size decreases as you move across a period from left to right.

Front

Why do atoms get smaller as you move across a period?

Back

Atoms get smaller because they have more protons, which increases the positive charge and pulls the electrons closer.

Front

Which element has a greater electronegativity: Chlorine (Cl) or Aluminum (Al)?

Back

Chlorine (Cl) has a greater electronegativity than Aluminum (Al).

Front

Which element has a greater electronegativity: Nitrogen (N) or Carbon (C)?

Back

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

Front

What is the trend of atomic radius in Group 1 as you move down the group?

Back

The atomic radius increases as you move down Group 1.

Front

What is the trend of ionization energy as you move across a period?

Back

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

Front

What is the trend of metallic character as you move down a group?

Back

Metallic character increases as you move down a group.
