The building blocks of matter that make up everything are called:

• proton

• atom

• molecule

• nucleus

The subatomic particles are:

• atoms

• protons

• neutrons

• nucleus

• electrons

The subatomic particles that go in the nucleus of an atom :

• proton

• neutron

• electron

The positive subatomic particle is:

• proton

• neutron

• electron

The negative subatomic particle is:

• proton

• neutron

• electron

The neutral subatomic particle is:

• proton

• neutron

• electron

The place where electrons are found according to modern atomic theory is the:

• electron oort

• energy levels

• electron orbitals

• nucleus

Valence electrons are found in the:

• nucleus

• first energy level of every atom

• biggest energy level of every atom

• electron cloud

The horizontal (left to right) rows on the periodic table are called:

• periods

• groups

• families

The vertical (up and down) columns on the periodic table are called:

• periods

• groups
