Chemistry 2

?
Mass Number
Total number of protons and electrons.
1 of 11
Proton Atomic
Number of protons in the nucleus
2 of 11
Note
The number of protons is equal the the number of elcetrons
3 of 11
Isotope
Atoms which have the same number of protns with the number of electrons
4 of 11
Number Of Neutrons
Mass number - the atomic number
5 of 11
Peridodic Table
Group- Number of electrons in the outer shell, Period- number of shel;ls an atom has.
6 of 11
Electronic Structure
1st shell= 2 electrons, 2nd shell=8 electrons, 3rd shell=8 electrons
7 of 11
E.g
nitogen has 7 electrons so the structure would be 2,5. aluminuim has 13 electrons so its structure would be 2,8,3
8 of 11
Ar
Mass of an atom always given
9 of 11
Mr
sum of masses of an induvidual atom
10 of 11
E.g
Ar(H)=1 Ar (O)=16, Mr(2*H)+(1*O)=18
