Periodic Table Trends

Front

What happens to electronegativity across a row and down a column in the periodic table?

Back

Electronegativity increases across a row and decreases down a column.

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

Its 1 valence electron is very far from the nucleus, so little energy is needed to remove it.

Front

What are the elements in groups 3 - 12 of the periodic table called?

Back

Transition metals.

Front

How does metallic character change across a period?

Back

Metallic character decreases across a period.

Front

What are the horizontal rows in the periodic table called?

Back

Periods.

Front

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

Back

The atomic radius increases as you move down a group.

Front

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

Back

Ionization energy increases as you move across a period.

Front

What are the vertical columns in the periodic table called?

Back

Groups.

Front

What is the general trend of reactivity for alkali metals as you move down the group?

Back

Reactivity increases as you move down the group.

Front

What is the trend of electronegativity for nonmetals as you move across a period?

Back

Electronegativity increases for nonmetals as you move across a period.
