Q

Explain in terms of electrons what occurs when sodium bonds with oxygen

A

Two electrons transferred to an oxygen atom from two different sodium atoms

17
Q

Why do sodium ions and chlorine ions form an ionic bond?

A

There is an electrostatic force of attraction between oppositely charged ions

18
Q

Why don’t sulphur ions and oxygen ions form ionic bonds with each other?

A

Both have negative charges so would repel

19
Q

What is the name for a substance made of billions of oppositely charged ions joined together?

A

Giant ionic lattice

20
Q

Define giant ionic lattice

A

A huge 3D network of ions
