1. Protons, Neutrons, Electrons
How Do We Find All 3?
And Where Do We Get These Parts Of The Atoms?

2. So, How Do We Use All These Numbers to Make Sense of What We Have?
Protons: can be identified by the ATOMIC NUMBER C 6
12.011
Therefore…
Carbon has
6 Protons

3. So, How Do We Use All These Numbers to Make Sense of What We Have?
Electrons: can be identified by the ATOMIC NUMBER C 6
12.011
Therefore…
Carbon has
6 Electrons

4. So, how can we find the Neutrons then?
Neutrons: can be found when taking the ATOMIC MASS and subtracting out the ATOMIC NUMBER C 6
12.011
ATOMIC MASS = 12
ATOMIC
NUMBER = 6 -
6 Neutrons

5. Practice!!!!
protons Mg 12
24.3
neutrons
electrons

6. Atomic Mass – Atomic Number
Magnesium
12 Protons
12 Electrons Mg 12
24.3
Neutrons =
Atomic Mass – Atomic Number
24 – 12 = 12 Neutrons

7. Practice 2!!!
protons Cl 17
35.5
electrons
neutrons

8. Atomic Mass – Atomic Number
Chlorine
17 Protons
17 Electrons Cl 17
35.5
Neutrons =
Atomic Mass – Atomic Number
= 19 Neutrons

9. Practice 3!!!
protons Bh
107
262.1
electrons
neutrons

10. Atomic Mass – Atomic Number
Bohrium
107 Protons
107 Electrons Bh
107
262.1
Neutrons =
Atomic Mass – Atomic Number
= 155 Neutrons

11. Name That Element!!! ??

12. HELP ME FIND THIS ELEMENT!!!
I am a metal with 35 Neutrons...help me find my name!?!?!?!
protons
Hint: I am missing from either Group 10, 11, or 12.
neutrons
electrons

13. Dum, Dum-Dum, Dum, Dum... protons 35 neutrons electrons
We search the 3 possible groups and we check Atomic Masses – Atomic NUMBERS to see which one gives us 35 Neutrons 35
neutrons
electrons

14. HAHA!!!! Zn 30
65.38
Zinc
is the answer!!!
