2 full orbitals, S and P
In a silicon atom, there are four filled orbitals. Specifically, there are two filled in the 1s orbital and two filled in the 2s orbital.
The sulfur atom has 16 electrons around its orbitals. The third energy level is the most tightly bound to the nucleus.
Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and 6electrons in the 2 p orbitals. The electrons are part of the first and second energy levels, the electron core. The next energy level, the last one, is the outermost energy which comprises the valence shell.
In a sulfur atom, the third energy level can contain a maximum of 18 electrons. The electrons are distributed among the different orbitals in the third energy level according to the rules of electron configuration.
There is one half-filled orbital in a chlorine atom. Chlorine has 17 electrons in its neutral state, distributed among 3s, 3p, and 3d orbitals. In the 3p subshell, there are three orbitals (px, py, pz), and if eight electrons are filled (as in the case of chlorine), one of these orbitals will contain only one electron, making it half-filled.
Sulfur has 4 half-filled orbitals, which are the three 3d orbitals and the 4s orbital. An orbital is considered half-filled when it contains one electron.
Three completely filled orbitals.
In a silicon atom, there are four filled orbitals. Specifically, there are two filled in the 1s orbital and two filled in the 2s orbital.
The sulfur atom has 16 electrons around its orbitals. The third energy level is the most tightly bound to the nucleus.
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.
Arsenic has three electrons occupying the three 4p orbitals in its valence shell. Hund's first rule tells us that they will each occupy separate orbitals before they start to pair up. So there are three half-filled orbitals in an arsenic atom.
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.
In a xenon atom, all five of its p orbitals are filled with electrons. Each p orbital can hold a maximum of 2 electrons, for a total of 10 electrons in the p orbitals of xenon.
A bromine atom has 7 half-filled orbitals: one in the 4s orbital, three in the 4p orbitals, and three in the 4d orbitals.
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).
Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and 6electrons in the 2 p orbitals. The electrons are part of the first and second energy levels, the electron core. The next energy level, the last one, is the outermost energy which comprises the valence shell.
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.
