Answer:
N,P,As,Sb
Step-by-step explanation:
THIS IS THE NOTCOMPLETE QUESTIONS
Among the groups of elements listed below, which have the same number of electrons in their highest occupied energy levels? A. Li, B, C, F B. Na, Mg, Al, S C. K, Ca, Rb, Sr D. N, P, As, Sb
Elements that has the same number of electrons in their highest occupied energy levels among the groups of elements listed are;
Nitrogen(N)
Phosphorus (P)
Arsenic (As)
Antimony(Sb)
Highest-energy atomic orbital in an atom is filled with electrons. It is also called valence orbital
Energy levels are different energies possessed by that electrons when it's occupying specific orbitals. This Electrons may be at higher energy levels when gained energy from the surroundings, or at lower energy level.
By examine the periodic table the atoms in the first period posses their electrons in 1 energy level, The atoms of the second period possess their own electrons in 2 energy levels and so on.
Therefore Nitrogen(N), Phosphorus (P), Arsenic (As), Antimony(Sb) have the same number of electrons in their highest occupied energy level
