The Atom 1.Parts of the atom 2.How to draw an atom
2
Parts of the atom 1.Proton 2.Neutron 3.Electron
3
Parts of the atom PartLocationChargeMassHow to find the number of: Proton In the nucleus Positive (+) 1 AMU Same as the atomic number Neutron In the nucleus Neutral (No charge) 1 AMU Atomic Mass minus the atomic number Electron Orbits the nucleus Negative (-) 1/1800 AMU Usually the same as the atomic number

5
The Periodic Table of Elements
9
Rules for Elements’ Symbols First letter is always capitalized
10
Rules for Elements’ Symbols First letter is always capitalized Second and third letters, if any, are always lower case
11
Helium
12
ProtonSame as the atomic number Neutron Atomic Mass minus the atomic number Electron Usually the same as the atomic number
13
ProtonSame as the atomic number Neutron Atomic Mass minus the atomic number Electron Usually the same as the atomic number p + :?n:?e - :?
14
ProtonSame as the atomic number Neutron Atomic Mass minus the atomic number Electron Usually the same as the atomic number p + :2n:?e - :?
15
ProtonSame as the atomic number Neutron Atomic Mass minus the atomic number Electron Usually the same as the atomic number p + :2n:4 - 2e - :?
16
ProtonSame as the atomic number Neutron Atomic Mass minus the atomic number Electron Usually the same as the atomic number p + :2n:2e - :?
17
ProtonSame as the atomic number Neutron Atomic Mass minus the atomic number Electron Usually the same as the atomic number p + :2n:2e - :2
18
Drawing the Helium Atom p + :2 n:2 e - :2
19
Drawing the Helium Atom p + :2 in the nucleus n:2 e - :2
20
Drawing the Helium Atom p + :2 in the nucleus n:2 in the nucleus e - :2
21
Drawing the Helium Atom p + :2 in the nucleus n:2 in the nucleus e - :2 orbits the nucleus
22
Drawing the Helium Atom p + :2 in the nucleus n:2 in the nucleus e - :2 orbits the nucleus p+
23
Drawing the Helium Atom p + :2 in the nucleus n:2 in the nucleus e - :2 orbits the nucleus p+ n n
24
Drawing the Helium Atom p + :2 in the nucleus n:2 in the nucleus e - :2 orbits the nucleus p+ n n e-
25
Drawing the Helium Atom p + :2 in the nucleus n:2 in the nucleus e - :2 orbits the nucleus p+ n n e- NICE!
26
Now Draw: A hydrogen atom:
27
Now Draw: A hydrogen atom:
28
Now Draw: A hydrogen atom: p + : n : e - :
29
Now Draw: A hydrogen atom: p + : 1 n : e - :
30
Now Draw: A hydrogen atom: p + : 1 n : 1 - 1 e - :
31
Now Draw: A hydrogen atom: p + : 1 n : 0 e - :
32
Now Draw: A hydrogen atom: p + : 1 n : 0 e - : 1
33
p + : 1 n : 0 e - : 1
34
p + : 1 n : 0 e - : 1 p+
35
p + : 1 n : 0 e - : 1 p+
36
p + : 1 n : 0 e - : 1 p+ e-
37
p+ e- Yeah Baby !
38
Now try: Lithium Beryllium
