Chemical Bonding

Question 1

What is ionic bonding?

Answer 1

• A lattice structure of alternating positive and negative ions
• the transfer of electrons
• Conducts electricity in molten/aqueous state as mobile electrons are present then

Question 2

What is metallic bonding?

Answer 2

-Positive ions in a sea of delocalized electrons

Question 3

What is covalent bonding?

Answer 3

• the sharing of a pair of electrons between atoms

- between non metallic elements
