Question

Will medal, please help!
When an oxygen atom forms an ion, it gains two electrons. What is the electrical charge of the oxygen ion?

A.
+2

B.
-1

C.
+1

D.
-2
I think B?

Answer 1

each electron has a negative charge, right?

Answer 2

Yes

Answer 3

So am I right then?

Answer 4

we are asking about the net electrical charge. an atom is electrically neutral, an ion has an excess charge (positive or negative)

Answer 5

well if electrons are negative, and an ion is a positive charge, then it would be 1+(-2) right?

Answer 6

@theEric

Answer 7

an ion is not a positive charge.
an ion is an atom that has either has an excess of negative charge or a deficiency
it is an electrically charged atom

Answer 9

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.

Answer 10

an oxygen atom that gains two electrons has a net negative charge of -2. That is the electrical charge of the ion.

THANK YOU!

Answer 12

Could you help me with another one?
