PERIODIC TRENDS

Front

Electronegativity __________ from left to right within a period and __________ from top to bottom within a group.

Back

increases, decreases

Front

As you move down a group, atomic radius increases because -

Back

you add more and more shells (energy levels)

Front

The energy required to remove electrons is the definition of:

Back

Ionization

Front

As you move across the periodic table from left to right, the atomic radius decreases. This is because -

Back

the number of protons increases, so attraction to electrons increases

Front

The atom with the largest atomic radius in Period 4 (row 4) is -

Back

K

Front

What is the trend of ionization energy as you move from left to right across a period?

Back

Ionization energy increases.

Front

What is the trend of atomic radius as you move down a group?

Back

Atomic radius increases.

Front

Define electronegativity.

Back

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

Front

What happens to the electronegativity of elements as you move down a group?

Back

Electronegativity decreases.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy decreases.
