Calcium has 20 electrons in total. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s², which indicates that there are no electrons in the 3p orbitals. The 3p orbitals are filled in the next element, scandium, which has 21 electrons.
3p
The maximum number of unpaired electrons in a 3p subshell is three. Each of the three p orbitals can hold one electron with the same spin before pairing occurs, according to Hund's rule. Thus, if all three orbitals are occupied by single electrons, the total number of unpaired electrons in the 3p subshell is three.
Since they are p orbitals, 6 electrons are occupied in the 3p orbital. there are 3 types of p orbital, px, py and pz
To construct a molecular orbital (MO) diagram for a sulfur atom, start by filling the atomic orbitals according to the Aufbau principle, Hund's rule, and the Pauli exclusion principle. Sulfur has 16 electrons, filling the 1s, 2s, 2p, 3s, and 3p orbitals up to the 3p level. For the sulfide ion (S²⁻), add two additional electrons to the 3p orbitals, resulting in a filled 3p subshell. The MO diagram will show bonding and antibonding orbitals, with the molecular orbitals formed from the combination of the atomic orbitals, highlighting the increased electron density that stabilizes the ion compared to the neutral atom.
In the third energy level (n=3), there are three sublevels: 3s, 3p, and 3d. The 3s sublevel has 1 orbital, the 3p sublevel has 3 orbitals, and the 3d sublevel has 5 orbitals. Therefore, the total number of orbitals within the 3s, 3p, and 3d sublevels is 1 + 3 + 5 = 9 orbitals.

The electron configuration of calcium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2. This means that calcium has 20 electrons, with two electrons in the 1s orbital, eight in the 2s and 2p orbitals, and eight in the 3s and 3p orbitals, and finally two in the 4s orbital.

There are no unpaired electrons in calcium, all 20 electrons are in pairs, i.e. each pair is configured in one orbital: 2x in 1s orbital 2x in 2s orbital 2x in each of the three 2p orbitals 2x in 3s orbital 2x in each of the three 3p orbitals and 2x in 4s orbital (these two are the valence electrons)
There are 2, 6 and 10 electrons in the 3s (1 suborbital), 3p (with 3 suborbitals: 3px, 3py, 3pz) and 5 sub orbitals in the 3d orbital: this makes a total of 18 electrons in 9 suborbitals
The 8 valence electrons for argon are located in the 3s and 3p orbitals, with two electrons in the 3s orbital and six electrons in the 3p orbital.
3p
In silver there are 2 electrons in 3s orbital, 6 electrons in 3p orbitals and 10 electrons in 3d orbitals. So there is a total of 18 electrons
The electron orbitals of silicon are 1s, 2s, 2p, 3s, and 3p. Silicon has a total of 14 electrons, with two electrons in the 1s orbital, eight electrons in the 2s and 2p orbitals, and four electrons in the 3s and 3p orbitals.
The maximum number of unpaired electrons in a 3p subshell is three. Each of the three p orbitals can hold one electron with the same spin before pairing occurs, according to Hund's rule. Thus, if all three orbitals are occupied by single electrons, the total number of unpaired electrons in the 3p subshell is three.
A silicon atom has 4 valence electrons. These electrons are paired up in the 3s and 3p orbitals. Therefore, a silicon atom does not have any unpaired electrons.
Silicon has three orbitals in its valence shell: one 3s orbital and two 3p orbitals. This gives it a total of four valence electrons.
