Bonding

How do covalent bonds form?

• Donating & receiving valence e- between atoms.
• Opposite slight charges attract each other between compounds.
• Scientists are still not sure how they form.
• Sharing valence e- between atoms.

What two types of atoms make a covalent bond?

• 2 Nonmetals
• 1 Nonmetal and 1 Metal
• 2 Metals
• 2 Noble Gases

What do we call a covalent bond where electrons are shared UNEVENLY or UNEQUALLY?

• Ionic
• Polar Covalent
• Nonpolar Covalent
• Van der Waals Force

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
