Warmup 12-13

Front

What is Atomic Radii?

Back

The measure of the size of the atom, specifically the distance between the nuclei of identical atoms that are bonded together.

Front

What happens to the size of atoms as you move down the periodic table?

Back

The atoms tend to get bigger because they have more energy levels.

Front

What happens to ionization energy and electronegativity as you move from left to right across a period?

Back

Both ionization energy and electronegativity increase.

Front

What is Ionization Energy?

Back

The energy required to remove one electron from a neutral atom of an element.

Front

What are Periodic Trends?

Back

Properties that show patterns when examined across the periods or vertically down the groups.

Front

What is the trend in atomic size as you go down a group in the periodic table?

Back

The atomic size increases.

Front

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

Back

Ionization energy increases.

Front

What is Electronegativity?

Back

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

Front

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

Back

Atomic radii decrease.

Front

What is the relationship between atomic size and energy levels?

Back

As the number of energy levels increases, the atomic size increases.
