1) BELLRINGER: What is the charge of Na by itself? What is the charge of Na in NaCl? What is the charge of H in H 2 ? What is the charge of H in HCl? 2) Worksheet #19 3) QUIZ #8

Worksheet #19 1) Lithium, Li, 3, 3, 1, +1 2) Sodium, +1, Chlorine, -1, NaCl 3) Sodium, +1, Nitrate, -1, NaNO 3 4) 2Na + Cl 2  2NaCl, synthesis

CLOSING ACTIVITY Another scientifically proven way to reduce stress is to actually doodle. Using the two lines given, make a doodle of whatever comes to your mind. Finally, put a grade (A,B,C,D,E) down for how hard you worked today on your worksheet.

QUIZ #8 1)Give the charge for calcium and fluorine when they are ions 2)Give the chemical formula for calcium fluoride 3)Write the balanced chemical equation if calcium and fluorine gas react to form calcium fluoride 4)What type of reaction is this?
