1. Protons, Neutrons, Electrons How Do We Find All 3? And Where Do We Get These Parts Of The Atoms? 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? ATOMIC NUMBER FProtons: can be identified by the ATOMIC NUMBER FPFProtons: can be identified by the A AA ATOMIC NUMBER C 6 12.011

3. ATOMIC NUMBER FElectrons: can be identified by the ATOMIC NUMBER FEFElectrons: can be identified by the A AA ATOMIC NUMBER So, How Do We Use All These Numbers to Make Sense of What We Have? C 6 12.011

4. ATOMIC MASS ATOMIC NUMBER FNeutrons: can be found when taking the ATOMIC MASS and subtracting out the ATOMIC NUMBER FNFNeutrons: can be found when taking the A AA ATOMIC MASS and subtracting out the A AA ATOMIC NUMBER So, Mr. M…how can we find the Neutrons then? C 6 12.011 ATOMIC MASS ATOMICNUMBER

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

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

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

8. ChlorineChlorine Cl 17 35.5 17 Protons 17 Electrons Neutrons = Atomic Mass – Atomic Number 36 - 17 = 19 Neutrons

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

10. Bohrium Bohrium Bh 107 262.1 107 Protons 107 Electrons Neutrons = Atomic Mass – Atomic Number 262 - 107 = 155 Neutrons

11. Name That Element!!! ?? ?? ??

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

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

14. HAHA!!!! Zn 30 65.38
