periodic trends and bonding review game

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases because you add more and more shells (energy levels).

Front

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

Back

Atoms tend to get smaller because the atoms have more protons.

Front

Why does atomic radius decrease from left to right across a period?

Back

The number of protons increases, so attraction to electrons increases.

Front

What type of bond is formed in CaF2?

Back

Ionic bond.

Front

What occurs during the formation of ionic bonds?

Back

Valence electrons are transferred.

Front

Define atomic radius.

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

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

Back

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

Front

What is electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases as you move down a group.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.
