Yippie for Friday!

Find a partner and go sit by them – only groups of 2!! Stay in the desks, but move them around if needed

Pick up a clicker and turn it on! (you can have one clicker per group or per person if you would like)

It might be helpful to take out your notes as well

You will also need a periodic table

1) What is the atomic number of Carbon?

a. 28b. 12.01c. 6d. 14

2) The atomic number is equal to:

a. The number of protonsb. The number of neutronsc. The number of protons + neutronsd. The number of electrons

3) What is the mass number for a zinc isotope that has 34 neutrons?

a. 34 b. 30c. 64d. 0

4) Using your periodic table, which of the following sulfur isotopes has the higher percent abundance:

sulfur-32 sulfur-33 sulfur-34

sulfur-35

a. sulfur-32b. sulfur-33c. sulfur-34d. sulfur-35

5) How many protons does potassium have?

a. 39.10b. 19c. 4d. 1

6) How many electrons are in a neutral atom of oxygen?

a. 8b. 16c. 16.00d. 6

7) Choose the correct statement below for a sodium atom that a charge of +1.

a. This atom has 11 protons and 11 neutronsb. This atom has 11 protons and 11

electronsc. This atom has 11 protons and 10 neutronsd. This at has 11 protons and 10 electrons

8) What is the symbol for lead?

a. Lb. Lec. Pbd. Sn

9) Which groups of the periodic table represent the “s” sublevel?

a. Groups 1A1 and 2Ab. Groups 3b-12bc. Groups 3A – 8Ad. I have no idea

10) What is the charge of an atom that has 15 protons, 12 electrons and 13 neutrons?

a. +1b. -1c. +3d. -3
