Enlace covalente

The video explains how atoms share pairs of electrons to form molecules through covalent bonds. It describes the formation of single, double, and triple covalent bonds when one, two, or three pairs of electrons are shared, respectively. Covalent bonds typically occur between nonmetal atoms that need to gain electrons to complete their outer electron shells.

What is formed when atoms share pairs of electrons?

• Covalent bond

• Metallic bond

• Ionic bond

• Hydrogen bond

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

• Four pairs

• Three pairs

• Two pairs

• One pair

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

• Quadruple covalent bond

• Triple covalent bond

• Double covalent bond

• Single covalent bond

Between which type of atoms do covalent bonds typically form?

• Noble gases

• Metals

• Nonmetals

• Metalloids

Why do nonmetal atoms form covalent bonds?

• To lose electrons

• To gain electrons

• To become ions

• To share protons
