Chemical Bonds and the Octet Rule

What is the octet rule in chemistry?

• Atoms are stable with eight neutrons in the nucleus.

• Atoms are stable with eight electrons in their outer shell.

• Atoms are stable with eight bonds.

• Atoms are stable with eight protons in the nucleus.

How does a covalent bond form?

• By sharing electrons between atoms.

• By transferring protons between atoms.

• By sharing neutrons between atoms.

• By transferring electrons between atoms.

Why does carbon form covalent bonds with hydrogen?

• To gain neutrons and become stable.

• To share electrons and achieve a full outer shell.

• To gain protons and become stable.

• To lose electrons and become stable.

What happens to sodium when it forms an ionic bond with chlorine?

• It loses a neutron and becomes negatively charged.

• It loses an electron and becomes positively charged.

• It gains an electron and becomes negatively charged.

• It gains a proton and becomes positively charged.

What is the result of the attraction between sodium and chlorine ions?

• Formation of a sodium chloride molecule.

• Formation of a hydrogen bond.

• Formation of a metallic bond.

• Formation of a covalent bond.
