The elements in group 15 Nitrogen, N; Phosphorus, P; Arsenic, As; Antimony, Sb and Bismuth, Bi all have a ground state with 3 unpaired electrons in p orbitals.
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)
three unpaired electrons
There are 3 unpaired electrons.
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
the proton number is 15

The answer is two.Third shell of sulfur is occupied by 6 electrons:3s2 3px2 3py 3pzof which the first 4 electrons (in 3s2 3px2) are paired (superscipted 2 means 2electrons per sublevel)and the other 2 electrons are unpaired (3py 3pz, no superscript means 1 electron per sublevel).
No, nitrogen is paramagnetic because it has 3 unpaired electrons in the 2p orbital. Electron configuration: 1s^2 2s^2 2p^3 There are three orbitals in the p orbital and they must be filled singly first before they can be paired and because there is only 3 electrons for 3 orbitals, all of them are unpaired.
Yes, nitrogen can form three covalent bonds. It has five valence electrons, three of which are unpaired. The three unpaired electrons can form covalent bonds.
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
Elemental nitrogen has 7 electrons.Thus, the first (or K) shell of electrons contains 2 of them (the maximum that the K shell can accommodate).The second (or L) shell of electrons contains the remaining 5, however, the maximum number of electrons that the L shell can accommodate is 8.Therefore, elemental nitrogen has three unpaired electrons that can be used to form covalent bonds.In ammonia (NH3) all three of those unpaired electrons are paired with hydrogen atoms.Leaving only a single unshared pair of electrons in the L shell.Technically, the pair of electrons in the K shell are also an "unshared" pair but they are unavailable for covalent activity so are generally not considered as such.
