hello i need help on my homework please could someone help me???

 

what is the difference between a chemical element and a compound

 

:confused:

An element is one type of atom, for instance gold, hydrogen, arsenic, caesium. Different types of atom/different elements are defined by the amount of protons in it's nucleus.

 

A combination of different elements/types of atom that have been bonded into a molecule forms a compound. For instance water is a compound of hydrogen and oxygen: one water molecule consists of two hydrogen atoms and one oxygen atom.
