The nitrogen family, group 15, is characterized by an s2p3 configuration.
Silicon is the only element with 18 protons, it form NO cations.
Nitride (of Nitrogen), Arsenide (of Arsenic), Antimonide (of Antimony), Bismuthide (of Bismuth) and Boride (of Boron)
The compound name for P3 is phosphorus trihydride. In this compound, the prefix "tri-" indicates that there are three hydrogen atoms bonded to the phosphorus atom. Phosphorus is a nonmetal element, and when it forms a compound with hydrogen, it follows the naming convention of adding the suffix "-ide" to the second element, in this case, hydrogen.
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
When an atom of phosphorus gains three electrons to become a phosphide ion (P3-), it will have a larger radius compared to the neutral phosphorus atom. This is because the additional electrons will occupy outer electron shells, leading to increased electron-electron repulsion and the expansion of the ionic radius.
Type of hybridization of molecule.
The elements with a s2 p3 electron configuration are located in the 5A (or 15) column of the periodic table: nitrogen, N; phosphorus, P; arsenic, As; antimony, Sb, and bismuth, Bi.
phosphorus has 15 protons and electrons: 1 s2 2 s2, 2 p6 3 s2, 3 p3 This adds up to a total of 15 electrons.
Silicon is the only element with 18 protons, it form NO cations.
S2- ion: [Ne]3s23p6
Definition: A set S1 is a superset of another set S2 if every element in S2 is in S1. S1 may have elements which are not in S2.
Sulfur
Yes. Argon is the only neutral element with 18 electrons. However, there can be other ions that can be isoelectronic (having same number of electrons) with argon. Cations such as K+, Ca2+ or Sc3+ have 18 electrons. Anions such as Cl-, S2- or P3- have 18 electrons.
