5. How many neutrons are there in this atom?
6. How many electrons are there in this atom?
7. What is the atomic weight of this atom?
8. Does the mass on the periodic table round to
the mass this atom has?
9. What atom is this?
9p+
10 n°
10. For each electron shown, write on the diagram to indicate which orbital (1s, 2s, 2p,...)
each electron is in.
11. Draw the orbital filling diagram for this atom. (Orbital filling is the thing with the boxes
and the arrows).
12. Write the electron configuration (1s"2s*) for this atom.

Answer 1

4) 9

5) 10

6) 9

7) 19

8) (I don't have a periodic table on me)

9) fluorine

10) 1s = 1st (2 electrons) 2s = 2nd (2 electrons) 2p = 2nd (6 electrons)

11)

12) 1s²2s²2p⁵
