30
Q

What is an ionic bond?

A

A bond between non-metal and metal atoms that involves atoms gaining or losing electrons and becoming positively or negatively charged and are therefore the ions are attracted to each other

31
Q

What is a compound?

A

Two or more different atoms chemically bonded together

32
Q

What is a metallic bond?

A

A bond between metal atoms. It is the attraction between positive ions and a sea of delocalised electrons

A

There are equal numbers of positive protons and negative electrons

34
