Detailed explanation-1: -Step 1 : Determine the number of protons and the number of electrons in the arrangement. Step 2 : Subtract the number of electrons from the number of protons to get a number N. This represents the net charge of the arrangement in terms of fundamental charge units (i.e. the charge on 1 proton).
Detailed explanation-2: -To calculate an atomic charge, simply subtract the number of electrons from the number of protons.
Detailed explanation-3: -Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
Detailed explanation-4: -AI Recommended Answer: In this case, the overall charge on the atom is equal to 7 + 9 = 16.
