Who really knows what an ATOM is anyway???
ATOMS = BUILDING BLOCKS of all Matter
Basic for :
- For chemistry
-for everything in the Universe.
ALL MATTER IS MADE UP of Atoms…………….
Atomic Structure - 2 REGIONS
**The number of protons identifies the atom.
Ex. 2 protons = He, 29 protons = Cu
Since it has 1 proton it must have 2 neutrons
Reviewers think this could lead to misconceptions!
All of the protons and the neutrons
The 3rd ring can hold up to 18 e-
The 1st ring can hold up to 2 e-
The 4th ring and any after can hold up to 32 e-
The 2nd ring can hold up to 8 e-
Mass # = 12 atomic # = 6
p+ = 6 no = 6e- = 6
6 p and 6 n live in the nucleus
