Rock Cycle - Chemistry (4)
Pre Lab 

Draw the number of electrons in the 1st, 2nd, and 3rd orbitals around the nucleus of sodium and chlorine.

Protons equal the Atomic Number. Neutrons are the Atomic Mass - Atomic Number. Remember the first orbital has 2 electrons maximum, the 2nd has 8 electrons, and the 3rd has 8 maximum.

How can the sodium and the chlorine "bond" to create a stable molecule of sodium chloride (halite)?


 

Name: Sodium
Symbol: Na
Atomic Number: 11
Atomic Mass: 23		 Name: Chlorine
Symbol: Cl
Atomic Number: 17
Atomic Mass: 35
