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

Answer:

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

a sample of a substance has a density of 1.75 g/cm3 and a mass of 14.7 g. What volume does the sample occupy?
Zigmanuir [339]

The volume occupied by the sample is 8.4 cm³

<h3>What is density?</h3>

The density is the ratio of mass of the object to its volume.

Given is the mass m =14.7 g and the density is 1.75 g/cm³, then the volume will be

ρ = m/ V

V =m /ρ

Substitute the values, we get

V = 14.7 /1.75

V = 8.4 cm³

Thus, the volume of the sample is  8.4 cm³.
