Question

Iron atoms have been detected in the sun's outer atmosphere, some with many of their electrons stripped away. What is the net electric charge (in coulombs) of an iron atom with 26 protons and 6 electrons?

Answer 1

Answer:

Q= 3.04×10^{-18} C

Explanation:

charge on the atom is difference of negative charge due to electrons and positive charge due to proton.

Since, charge on both electron and proton is same, the net charge is given by:

Q = $N_1e =N_2(-e)$

Net charge

Q= 26(1.6×10^{-19})-7(1.6×10^{-19})

Q= 3.04×10^{-18} C
