El enlace covalente

The video explains the essential non-metallic atoms like carbon, hydrogen, oxygen, and nitrogen, and their role in forming molecules. It discusses how these atoms bond through electron sharing, forming covalent bonds. Chlorine's unique bonding due to its electron needs is highlighted, along with the ability of atoms to form multiple covalent bonds, exemplified by water molecules. Carbon's versatility in forming diverse organic molecules through multiple covalent bonds is also covered.

Which of the following elements is not typically found in isolation but forms molecules?

• Argon

• Neon

• Helium

• Carbon

What is the primary reason non-metallic atoms form covalent bonds?

• To lose electrons

• To gain a complete outer shell

• To become positively charged

• To become negatively charged

What type of bond is formed when two non-metallic atoms share electrons?

• Hydrogen bond

• Covalent bond

• Metallic bond

• Ionic bond

Why can chlorine only form a single covalent bond?

• It can only share electrons with metals

• It is missing one electron

• It has a full outer shell

• It is a noble gas

What allows carbon to form large chains and rings of atoms?

• Its ability to form four covalent bonds

• Its ability to form ionic bonds

• Its ability to form metallic bonds

• Its ability to form two covalent bonds
