Answer:
net charge of the oxygen atom is NEGATIVE
Step-by-step explanation:
As we know that an oxygen atom is initially neutral
Atomic number of oxygen atom is 8
Atomic number of oxygen shows the total number of protons in it
now we can say that for neutral condition of oxygen atom we have
number of electrons = 8
number of protons = 8
Now if the neutral atom add up by two more electrons then
total number of electrons in it = 8 + 2 = 10
total number of protons = 8
so here net charge of the oxygen atom is NEGATIVE
