2 electrons are in magnesiums last energy level
There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
The third energy level of an atom can hold eight electrons.
18 electrons
The third principal energy level can hold a maximum of 18 electrons. Two are in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.
2
There are 8 electrons in the third energy level of a calcium atom.
There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
the maxium number of electrons that the third energy level can occupy is 18
No. Maximum of 18 electrons is possible in third energy level.
The third energy level of an atom can hold eight electrons.
18 electrons
2 electrons. Magnesium has 12 total, in 3 shells, 2,8,2There are two electrons in magnesium's third energy level.
no, up to 18 electrons only in the 3rd energy level.
The third energy level contains s,p, and d subshells. These subshells hold 2,6, and 10 electrons respectively. Thus, in total the third energy level can hold 18 electrons.
Helium has only one energy level with two electrons. It does not have electrons in other energy levels in its ground state.
possibly
There are six electrons are in the second energy level of magneisum. A further two are on the first energy level and the last two are on the third energy level.
