how do atoms sometimes react together and how do they do it?

transferring electrons to form chemical bonds. this happens when metals react with non-metals. if the reacting atomms are all non-metals, then the atoms share electrons to form chemical bonds

1 of 7

what happens when a metal bonds with a non-metal?

they metal atom give one or more electrons to the non-metal atom. both atoms become charged particles called ions.

2 of 7

what do metal atoms form?

positively charged ions (+)

3 of 7

what do non-metal atoms form?

negatively charged ions (-)

4 of 7

what are ionic bonds?

strong forces of attraction are the chemical bonds that form when there's strong attractions between the positive and negative ions in a compund of a metal and non-metal.

5 of 7

what are covalent bonds?

when each pair of shared electrons forms a chemical bond between atoms

6 of 7

what happens to the charges on the ions in compunds between metals and non-metals?

the always cancel each other out
