• atoms with a positive or negative charge
• atoms with no charge
• atoms with ONLY a positive charge
• atoms with ONLY a negative charge

When an atom loses a valence electron, it becomes a(n) _____________ ion.

• positive
• negative
• neutral
• polyatomic

Negative ions form when atoms _________ valence electrons.

• lose
• gain
• share

Subatomic particles with a negative charge

• Electrons

• Neutrons

• Protons

• Quarks

What is one way Neutrons are different from electrons?

• they both are negative

• neutrons have no charge, while electrons have a negative charge

• Both are in the nucleus( center of atom)

• Electrons are inside nucleus and neutrons are outside the nucleus.
