the answer is 12!
A neutral xenon atom would have 54 electrons filled in its electron shells.
In a cadmium atom, all 27 s orbitals are filled with electrons. Cadmium has 48 electrons, and the s sublevel can hold a total of 2 electrons per orbital, so 27 orbitals are needed to accommodate all the electrons.
There are two completely filled orbitals in this atom: the 1s orbital with 2 electrons and the 2p orbitals with 6 electrons. The 2s orbital and 3s orbital are not completely filled.
In an arsenic atom, there are three half-filled orbitals. These are the 4s, 4p, and 4d orbitals. Each of these orbitals can hold a maximum of 2 electrons, so there are a total of 6 electrons in the half-filled orbitals of arsenic.
There are two orbitals that are completely filled in this atom: the 1s orbital with 2 electrons (1s2) and the 2s orbital with 2 electrons (2s2). The 2p orbital is not completely filled, as it should have a total of 6 electrons (2p6).

In an atom of chromium, there are a total of 24 electrons, leading to a fully filled 3s orbital (2 electrons) and a fully filled 3p orbital (6 electrons). The 3d orbital would have 5 completely filled orbitals since it can hold a maximum of 10 electrons.
If the s and p sublevels are filled in an atom of an element in period 3, then the orbitals filled in this atom would be 1s, 2s, 2p, 3s, and 3p. Each s sublevel can hold a maximum of 2 electrons, while each p sublevel can hold a maximum of 6 electrons.
No, xenon is a noble gas and typically does not form anions. It is more stable as a neutral atom due to its filled outer electron shell.
A neutral xenon atom has 54 electrons. Two of its electron shells would be completely filled, with 2 and 8 electrons, leaving 44 electrons in the remaining electron shells.
Selenium has four half-filled orbitals - the 4s, 4p_x, 4p_y, and 4p_z orbitals. This is because selenium has four electrons in its 4th energy level.
An atom of xenon contains 54 electrons, the atomic number of xenon.
