The atomic mass of an element whose atoms consist of eight protons, nine neutrons, and eight electrons is (ignore the periodic table entry for this element and only consider what the atomic mass would be given the number of subatomic particles in this question).

8
16
17
25

I believe it would be 17. This is calculated by adding up the number of protons and neutrons together in this case

8 protons + 9 neutrons = 17 subatomic particles altogether in nucleus of atom.

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
