Ionic and Covalent Bonding

When an atom loses an electron, it becomes a

• positive ion

• negative ion

• neutral ion

• neutral atom

Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost energy level

Ionic bonds are between...

• Metal and Non-metal
• Non-metal and Non-metal
• Metal and Metal

How are ionic bonds formed?

• Transfer of electrons
• Sharing of electrons

Where are the nonmetals located on the periodic table? 

• Blue

• Red

Ionic bonds form between two ions that have...

• ionic compounds
• negative charges
• positive charges
• opposite charges
