Question

A singly ionized helium ion has 2 protons in the nuclues and only a single election moving around the nuclues Let us assume that the average distance between the nuclues What is the charge in Coulombs of the electron cloud surrounding the nucleus What is the charge in Coulombs of the nucleus What is the overall charge in Coulombs of the singly ionized helium ion Calculate the Coulomb force of attraction of the entire nucleus on a single electron in th.e cloud surrounding the nucleus. if you add two neutrons to the nucleus, how will that change your answer to # 3 Explain your reasoning

Explanation / Answer

1)

charge of electron = -1.6 x10^-19 C

2)

charge of nucleus = + 3.2 x 10^-19 C

3)

overall charge = 1.6 x 10^-19 C

4)

F = k 2e^2 /r^2

r = 5.5 x 10^-11 m

F = 0.000000152 N

5)

force doesnt change as charge of neutron is zero
