If number of electrons in an atom is 8 and number of protons is also 8, then
i) what is the atomic number of atom ? Ii) what is the charge on the atom?

Text Solution

Verified by Experts

i) The atomic number of atom is 8.
ii) The electronic configuration of atomis 2, 6. By gaining two electrons it will get nearest inert gas configuration Neon. So, the charge on the atom is `-2.`
