What is the primary function of a chemical bond?

• To create energy

• To hold atoms together

• To destroy atoms

• To repel atoms from each other

What are valence electrons?

• Electrons in the innermost shell

• Electrons in the outermost shell

• Protons in the nucleus

• Neutrons in the nucleus

How is an ionic bond formed?

• By sharing protons

• By losing and gaining electrons between atoms

• By sharing neutrons

• By sharing a pair of electrons

What is a positively charged ion called?

• Cation

• Anion

• Neutron

• Proton

What type of bond involves the sharing of a pair of valence electrons?

• Ionic bond

• Hydrogen bond

• Metallic bond

• Covalent bond

In a polar covalent bond, how is the electron pair shared?

• Unequally, towards the more electronegative atom

• Equally between atoms

• Equally towards the less electronegative atom

• Not shared at all

What happens to the electron pair in a polar covalent bond?

• It is shared equally

• It is shared with a proton

• It is displaced towards the more electronegative atom

• It is lost
