Answer:
16) 6 electrons
17) 6 protons
18) 6 neutrons
19) 4 electrons
20) 6
Explanation:
There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.

This is really a math question. If a person is supposed to consume 8, 8 oz glasses of water in one day than you would multiply
8 x 8oz =64 oz. than 64 oz x 30 days= 1920 oz in one month
because that is a large number you might want to break it down to gallons.
1920 oz divided by 128 oz (one gallon)= 15 gallons in one month.
