There are 10 electrons in the 4d subshell of the ground state of Xenon.
The ground state, which is the lowest energy level of an atom, contains the least amount of available energy. Electrons in the ground state have the lowest possible energy and are closest to the nucleus.

When a positively charged object is grounded, electrons from the ground will flow into the object to neutralize the positive charge. This movement of electrons will cause the object to become neutral in charge.
When a positively charged object is grounded, electrons from the ground are free to move onto the object. These electrons neutralize the positive charge by transferring to the positively charged object, allowing the excess electrons on the object to flow into the ground. This flow of electrons equalizes the charge between the object and the ground.
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.
There are 10 electrons in the 4d subshell of the ground state of Xenon.
The element with the lowest atomic number that contains 10 p electrons in the ground state is neon. Neon has an atomic number of 10, and in its ground state, it has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 6 electrons in the 2p orbital.
Boron has 2 electrons in its 2p orbitals in its ground state. The 2p subshell can hold a maximum of 6 electrons (2 electrons per orbital), but in the ground state, boron only has 2 electrons in the 2p orbitals.
There are four electrons with l=1 (p orbital) in the ground state of chlorine. This is because a chlorine atom has 17 electrons, and the p subshell can hold a maximum of 6 electrons (2 electrons per px, py, and pz orbital).
Magnesium has atomic number 12 and so has 12 protons in the nucleus and 12 electrons in the neutral atom. It has three stable isotopes with 12, 13 or 14 neutrons. The neutrons have no real effect on the electronic structure. The ground state consists of the 1st shell of two electrons and the 2nd shell of 8 electrons. The last two electrons begin the 3rd shell and reside in the subshell named 3s. The last two electrons are the valence electrons.
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
The first-row transition metal with the most unpaired electrons is manganese (Mn). Its expected ground-state electron configuration is [Ar] 3d5 4s2, meaning it has 5 unpaired electrons in the 3d subshell.
Manganese (Mn) contains 3d5 electrons in its ground state electron configuration.
First, find the atomic number which tells you the total number of electrons. Gallium has atomic number 31, so it has 31 electrons. Next, look to see what period and group it is in. It is in period 4 and group XIII. This means that there will be 3 valence electrons (outermost electrons) and they will be in the 4th energy level. Also note that gallium is a p-block element, so the valence electrons will be in the 4 p subshell. Now, on to writing the electron configuration, adding electrons in order until we get to 31 electrons.1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1 and then placing the 3d10 before the 4s2 you get1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p1. Note there are 31 electrons and that the outermost are in the 4th energy level (period 4) and that there are 3 valence electrons in the 4th level (4s2 + 4P1) and the final shell being filled is the p subshell (as it is a p-block element). All checks out.
atomic mass = protons + neutronsprotons = atomic mass - neutrons = 18 - 8 = 10 protons (Neon)In ground state, protons = electrons = no charge-1 charge means gain of 1 e-, so number of electrons = 11 electrons
