Q-6. If the number of electrons in an atom is 8 and number of protons is also 8, then:
(a) What is the atomic number of the atom?
(b) What is the charge on the atom?
(c) What is the symbol of the atom


a) An Atomic number of an atom is the number of protons of that atom.
So, the atomic number will be 8. 

b) As, the number of electrons and number of protons both are the same, the net charge will be neutral because electrons are negatively charged and protons are positively charged, so all the negative charges are balanced with the positive charge.

c) Atomic number 8 is of oxygen. 
The symbol is as follows-
