Question

Complete the table with the mass number, number of protons, number of neutrons, and number of electrons for the elements shown.

Answer 1

Step-by-step explanation:

The Proton number for flourine will be 9

Then the mass number which will be protons+ neutrons will be 19

Argon which has a mass number of 40

to find the proton number of argon it will be 40-22=18

then the electron number will just be the same as proton number

then calcium the proton will be the same as electron so it will be 20

then neutrons will be mass number -proton number

which is 21

hope this helped

and pretty cool you use a mac
