Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key concept in understanding chemical bonding and reactivity.

Front

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

Back

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

Front

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

Back

Carbon (C) has a higher electronegativity than Arsenic (As).

Front

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

Back

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

Front

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

Back

The atomic radius generally increases as you move down a group in the periodic table.

Front

Which atom has the largest atomic radius in Group 18?

Back

Radon (Rn) has the largest atomic radius in Group 18.

Front

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

Back

The atomic radius generally decreases as you move from left to right across a period.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the relationship between electronegativity and atomic radius?

Back

Generally, as electronegativity increases, atomic radius decreases because the nucleus exerts a stronger pull on the electrons.

Front

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

Back

Electronegativity generally decreases as you move down a group in the periodic table.
