What element has ns2np3?
Nitrogen
The general electronic configuration ns2np3 holds true for the Nitrogen family which are the group 15 elements. These include Nitrogen, Phosphorous, Arsenic, Antimony and Bismuth.
What element has an electron configuration of 1s2 2s2 2p3?
Element with electron configuration 1s2 2s2 2p3 is Nitrogen (N.) It has two electrons in 1s, two in 2s, and three in 2p (arbitrarily two in 2px and 1 in 2py.)
What group in the periodic table has the valence shell configuration ns2np2?

What element has an electron configuration of 14?
silicon
Hence, the answer is silicon which has 14 electrons. Note: The electrons present in the inner orbitals are not available for interaction or bond formation with other atoms.
What elements are in the nitrogen family?
nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
Which elements release the most energy by gaining an electron?
The elements that can release energy by gaining an electron are “Chlorine and Silicon”. Explanation: On moving from left to right across the periodic table, electron affinity increases. Therefore, chlorine has a higher electron affinity than silicon.
Which group has a valence shell electron configuration ns1?
alkali metals
All of the alkali metals have a single s electron in their outermost principal energy. Recall that such electrons are called valence electrons. The general form for the electron configuration of each alkali metal is ns1, where the n refers to the highest occupied principal energy level.
Which group of elements have the valence electron configuration ns2np4?
The group 16 elements, the chalcogens. All the chalcogens have the valence shell electronic configuration ns2 np4. Oxygen is unique in its high electronegativity, so it tends to form compounds in the -2 oxidation state.
