Sub-atomic particles
• Protons (uud) +1 charge, in nuc., 1 amu
• Electrons -1 charge, outside nucleus
in shells, 0 a.m.u
• Neutrons (udd) “neutral”, in nucleus, 1
a.m.u.
Atoms
• Smallest unit of an element that
maintains all the properties of that
element.
• A combination of protons, neutrons
and electrons
Elements
• Protons determine the element
• S, P, O, N, C, H,
• Draw a pie graph of elements in the
Earth, and in living things.
• Note the 2 main elements of the
atmosphere
Molecules and Compounds
• When atoms bond together
• Water, glucose, proteins
