Metallic and Covalent Bonding (Q2W3)

How are covalent bonds formed?

• Covalent bonds are formed when two atoms transfer electrons.

• Covalent bonds are formed when two atoms repel each other.

• Covalent bonds are formed when two atoms attract each other.

• Covalent bonds are formed when two atoms share electrons.

What is the difference between a covalent bond and a metallic bond?

• A covalent bond is formed by transferring electrons, while a metallic bond is formed by sharing electrons.
