Covalent bond

The video tutorial explains how pairs of electrons form molecules through covalent bonds. It describes how single, double, and triple covalent bonds are created by sharing one, two, or three pairs of electrons, respectively. The tutorial also highlights that covalent bonds typically occur between nonmetal atoms, which need to gain electrons to achieve a full outer shell.

What is formed when pairs of electrons come together to create molecules?

• Metallic bonds

• Covalent bonds

• Hydrogen bonds

• Ionic bonds

How many pairs of electrons are shared in a covalent double bond?

• Three pairs

• Four pairs

• One pair

• Two pairs

What type of bond is formed when three pairs of electrons are shared?

• Single covalent bond

• Double covalent bond

• Triple covalent bond

• Quadruple covalent bond

Between which type of atoms do covalent bonds typically form?

• Noble gases

• Metalloids

• Nonmetals

• Metals

Why do nonmetal atoms form covalent bonds?

• To become positively charged

• To gain electrons

• To lose electrons

• To become negatively charged
