Hlo mate,
I think that All matter is composed of atoms; atoms of the same element are the same, and atomsof different elements are different; atoms combine in whole-number ratios to form compounds. A proton is larger than an electron. proton: 1+; electron: 1−; neutron: 0. The atomic number is the number of protons in a nucleus.
