  1. P.O.G.I.L Atom Structure Data Information Atom are the smallest unit of matter that make up everything! Atoms are made of 3 subatomic particles. Atoms are made of protons, neutrons and electrons. Protons are located in the nucleus which is located in the center of the atom. Protons have a ‘+1’ charge (much like a battery has a + charge on it). Protons have a mass of 1 amu = 1.672621898(21)×10-27 kg. = 0.0000000000000000000000000017 kg. Neutrons are located in the nucleus which is located in the center of the atom. Neutrons are neutral, they have no charge (like a dead battery). Neutrons has a mass of 1 amu = 1.672621898(21)×10-27 kg. = 0.0000000000000000000000000017 kg. Electrons are located in the clouds of the atoms. The word “cloud” represents the layers, i.e. orbits, of the electrons as the whiz around the atom’s nucleus. . Only 2 electrons on the first shell (cloud). Only 8 electrons on the second shell (cloud) and only 8 electrons on the 3rd shell(cloud). This rule only pertains to the 1st 18 elements on the periodic table. Electrons have a charge of ‘-1’ (much like a battery has a – charge at one end). Electrons mass is thousands of times smaller than protons and neutrons so we say it has no mass although it really does. The mass is just soosmall that it just doesn’t count. Imagine a dog has fleas. If you weigh the mass of the dog say it is 20 kg. Now add some fleas to the dog. Did the mass of the dog really change enough to count? This is why we ‘say’ electrons have no mass. Isotopes are atoms of the same element that contain equal numbers of protons but different numbers of neutrons in their nucleus. Isotopes are atoms of the same element that have different atomic masses. Ions are atoms with a charge. The atom has lost or gained electrons therefore protons do not equal electrons. Amu – atomic mass unit

  2. APE MAN Pneumonicnote: APE MAN Pees in the middle! A – Atomic Number P – Protons E – Electrons M – Mass Number A – Atomic Number N - Neutrons How to use APE MAN A = P = E M - A ------ = # Neutrons Example: How to use APE MAN (for a neutral atom) read the fine print! A 2 = P = 2 protons = E = 2 electrons M 4 mass number - A - 2 ------ -------- = # Neutrons = 2 Neutrons
