If the number of electrons in an atom is 8 and the number of protons are also 8 , then (i) What is the atomic number of the atom? And (ii) What is the charge on the atom?
(i) The atomic number of an atom is equal to the number of protons in the nucleus of the atom. In this case, you mentioned that the number of protons is 8, so the atomic number of the atom is also 8.
(ii) The charge on an atom is determined by the balance between the number of protons (positively charged) and electrons (negatively charged). In this case, the number of protons is 8, and the number of electrons is also 8. Since the number of protons and electrons is the same, the atom has a neutral charge. It is neither positively nor negatively charged, so its charge is 0.
