2. U. NILULUI alla electron D. proton only If the first and second energy levels of an atom are full, then what would be the total number of electrons in the atom? A. 6 D. 18 C. 10 B. 8
The total number of electrons would be ten (10) since the first energy level can contain only 2 electrons in the 1s sublevel then the second has 2s with 2electrons and 2p with 6 electrons, adding all theseelectrons will give us a total of ten
