Bonding/Periodic Table Organization

An atom that gains or loses an electron becomes

• an isotope

• a new element

• an ion

• a molecule

When an atom gains an electron it becomes

• negatively charged

• positively charged

• neurtal

Ionic bonds happen when valence electrons are

• shared

• too heavy

• transferred

Valence electrons are

• neutral (no charge)

• found in the outer most energy level of the atom

• equal to the number of protons

Which type of bond occurs between non metals?

• covalent bonds

• ionic bonds

• metallic bonds

• all types of bonds

What type of bond forms CaF₂

• covalent bond

• ionic bond

• metallic bond

• all answers are correct

What is the charge of an aluminum ion that has 13 protons and 10 electrons?

• 3+

• 3 -

• no charge

3. What do atoms that form positive ions tend to do?

• Tend to lose electrons

• Tend to lose protons

• Tend to gain electrons

• Tend to gain protons

5. What happens when the sodium atom loses an electron?

• It become negatively charged

• It become positively charged

• none

6. What usually forms the negative ion?

• Nonmetals

• Metal
