E- ELECTRONS A- Atomic #
the atomic number is the amount of protons in the nucleus P- Protons
Protons are found in the nucleus. Electrons- found outside in energy shells. They are 2000 times smaller than protons. Electrons are the only part of the atom that bond with other atoms Mass-Atomic number=Neutrons Atomic mass the total mass of the protons, neutrons, and electrons.
*because of average, mass is always messy, this helps distingusih atomic mass from atomic number. Atomic number When subtracted by the mass, the atomic number equals the number of protons. Neutrons Found in the nucleus, they are the same size as protons. They bond the protons together. Neutrons are found when the atomic mass is subtracted by the atomic number. A.P.E. doesn't apply when the atom is in a bonding situation and is turned into an ion. A.P.E applies when the atom isn't in a bonding situtation. M.A.N can be used when we want to find how many neutrons there are. You subtract the mass by the atomic number and you get; NEUTRONS. When and How you use it. A- atomic number number of protons number of electrons atomic mass A.P.E.M.A.N Not Rounding Atomic Mass confusing neutrons with electrons. electrons- these have a negative charge. They are found in energy shells around the neucleus
