Periodic Table Unit Test Review

Front

What element has chemical properties most similar to calcium (Ca)?

Back

Beryllium (Be)

Front

Why do atoms get bigger as you move down the periodic table?

Back

Atoms have more energy levels.

Front

How do valence electrons affect the reactivity of an element?

Back

The number of valence electrons determines how easily an element can react with others.

Front

Which element has the fewest valence electrons: beryllium (Be), sodium (Na), oxygen (O), or neon (Ne)?

Back

Sodium (Na)

Front

Where are metals located on the periodic table?

Back

On the left side.

Front

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

Back

The atomic radius increases.

Front

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

Back

Ionization energy generally increases.

Front

What are the main characteristics of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Front

What is the significance of the periodic table's groups (columns)?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

What is the significance of the periodic table's periods (rows)?

Back

Elements in the same period have the same number of energy levels.
