Periodic Trends

Front

What is the trend of atomic radius across a period and down a group?

Back

Atomic radius decreases across a period and increases down a group.

Front

How does electronegativity change as you move down Group 16?

Back

Electronegativity decreases as you move down Group 16.

Front

Which element has a higher electronegativity: Cl or Al?

Back

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

Front

True or False: Metals are good conductors of heat and electricity.

Back

True.

Front

Which halogen has the greatest electronegativity: Cl, Br, I, or At?

Back

Chlorine (Cl) has the greatest electronegativity.

Front

Define electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is ionization energy?

Back

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

Front

Describe the trend of ionization energy across a period.

Back

Ionization energy generally increases across a period.

Front

What happens to the ionic radius of metals as you move down a group?

Back

The ionic radius of metals increases as you move down a group.

Front

What is the relationship between atomic size and electronegativity?

Back

As atomic size increases, electronegativity generally decreases.
