Bonding

Question 1

What is ionic bonding?

Answer 1

• The electrostatic force of attraction between oppositely charged ions formed by electron transfer.

Question 2

Do metal atoms lose or gain electrons?

Answer 2

Metals lose electrons and form +ve ions. Non-metals gain electrons and form -ve ions.

Question 3

What is the electron configuration for Mg?

Answer 3

Mg = 1s^2 , 2s^2 2p^6, 3s^2 turns into Mg ^2+ = 1s^2, 2s^2, 2p^6

Question 4

What are the characteristics of ionic bonding?

Answer 4

• Ionic bonding is stronger and the melting points higher when the ions are smaller and/or have higher charges.
