I need help with the question circled

Chemistry
1 answer:
klio [65]3 years ago

Ahh the charges! I know just how to help!!

One thing I do is I draw each individual proton or electron out. Make sure you label each proton with a + and each electron with a -.

Then I cross them out. For each proton you cross out, cross out an electron and vice-versa.

If you end with a proton, then the atom is positive.

If you end with an electron, then the atom is negative.

If you end with nothing, then it is neutral.

HOPE THIS HELPS!!!!!! Let me know if you have more questions!!
