The nitrogen family, group 15, is characterized by an s2p3 configuration.
Elements with configurations ending in ns2np3 will lie in group 5A (like nitrogen or phosphorus.)
Group V A elements.
VA
Boron
When an element from anions, the radius of the ion increases when compared to that of the neutral atom. The same is the true for the element (phosphorus) and its anion (phosphide ion).
P3+
the element sulphur (S) due to the presence of unpaired electron.
P3+
No. S2- is a monatomic ion. A polyatomic ion contains at least two atoms. You can identify a polyatomic ion as it will have the symbols for more than one element (OH-), a subscripted number (O22-), or a combination of the two (CO32-). The superscript in the ion only indicates the charge.
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.
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.
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
It is P cubed or P3.
When an element from anions, the radius of the ion increases when compared to that of the neutral atom. The same is the true for the element (phosphorus) and its anion (phosphide ion).
163
Cl & K ions are isoelectronic with Ar.
P3 means to do 3 purl stitches.
