	i am doing a project and i need to know how many neutrons calcium contains please help me

Duh! that is such an easy one! here is how you find it. Take the atomic mass which is the number below the chemical sign. in this case the number is 40.03. lets just round that to 40. then you subtract the atomic number from that so you do 40-20 and get 20 it is like super easy!
