F = k q1 q2/r2

Question 5

How is atomic mass determined?

Answer 5

By the number of protons.

Question 6

When valence electrons are closer to the nucleus, will the attraction be higher or lower?

Answer 6

The attraction would increase.

Question 7

What if the valence electrons are farther away?

Answer 7

Then the attraction is less.

Question 8

What is the relationship between coulombic and distance?

Answer 8

The farther away the lesser attraction, and the closer the stronger.

Question 9

The farther you go down on a periodic table what happens? What about going across?

Answer 9

Down - They gain more electrons, protons, and shells.
Across - More protons are being gained.
