Forming Bonds: Exploring Covalent Bonds

The video tutorial explains covalent bonds, which form when atoms share electrons, making them more stable. It illustrates this with examples of hydrogen and chlorine bonding, as well as the formation of water molecules. The tutorial also defines molecules as groups of atoms held together by covalent bonds, highlighting that a water molecule retains the properties of water found in larger bodies.

What type of bond is formed when atoms share electrons?

• Covalent bond

• Hydrogen bond

• Metallic bond

How many valence electrons does a chlorine atom have?

• Three

• Seven

• Five

• One

In a water molecule, how many hydrogen atoms bond with oxygen?

• Four

• Three

• Two

• One
