Which correctly uses the patterns in the periodic table to describe what is happening in the model?

a)

Sodium is in period 3 and therefore has 3 energy levels. Chlorine is also in period 3 and has 3 energy levels. Since they have the same number of energy levels, the form a molecule.

b)

Sodium is in group 1 and therefore has 1 valence (outer) electron. Chlorine is in group 17 and therefore has 7 valence electrons. When they combine, they form a molecule that has a full valence shell of 8 electrons.

28.

Which correctly uses the patterns in the periodic table to describe what is happening in the model?

a)

Oxygen is in group 16 and therefore has 6 valence (outer) electrons. Hydrogen is in group 1 and therefore has 1 valence electron. When one oxygen and two hydrogen atoms combine, they form a molecule that has a full valence shell of 8 electrons.

b)

Oxygen is in period 2 and therefore has 2 energy levels. Hydrogen is in period 1 and therefore has 1 energy level. Since they have the same number of energy levels, they form a molecule.
