Question

*An atom has 25 protons, 30 neutrons, and 25 electrons. What is the charge of the atom's nucleus?
A. +25
B. +30
C. -25
D. -30
Please explain why you got the answer because I don't get this and I have a test next week about this, thank you! Plz

Answer 1

I think it's +25 because there is 25 protons and its inside of the nucleus and 25 electrons is negative but it's outside of the nucleus and last the neutrons has no change so I think it's +25. Am I right or wrong, please explain thank you

Answer 2

the answer is a, because it asks specifically for the nucleus. This means that since the neutrons have zero charge and protons in total have +25 charge, then +25+0=+25
If it was asking for the whole atom, then the charge would be 0 because of the -25 charge of all the electrons. Justsome info for when you have your test :) good luck

Answer 3

Thank you so much for explaining thank you you have a fabulous day! :)
