PS Chapter 5 Review

The order of elements in the periodic table is based on

• the number of protons in the nucleus.
• the electric charge of the nucleus.
• the number of neutrons in the nucleus.
• atomic mass.

Atoms of elements that are in the same group have the same number of

• protons
• neutrons.
• valence electrons.
• protons and neutrons.

Which of the following elements is an alkali metal?

• calcium
• magnesium
• mercury
• sodium

Carbon and other nonmetals are found in which area of the periodic table?

• on the left-most side
• on the right side
• in the middle column of the periodic table
• in the bottom rows

How was Mendeleev’s periodic table arranged?

• by increasing atomic mass
• by decreasing atomic mass
• by increasing atomic number
• by decreasing atomic number

Each column of the periodic table is

• period
• group
• row
• element

The periodic law states that elements that have similar properties appear

• to the left of each other.
• to the right of each other.
• at every tenth element.
• at regular intervals.

As you move from up to down in a column of the periodic table, elements have

• fewer protons.
• a lower atomic number.
• a higher atomic number.
• a higher group number.

Elements that belong to the same group have the same number of

• valence electrons.
• neutral electrons.
• inner electrons.
• total electrons.

Atoms that gain or lose electrons are called

• metals
• ions
• nonmetals
• isotopes
