The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
The electron configuration of phosphorus is [Ne]3s2.3p3.
The element with a valence electron configuration of 2s22p3 is phosphorus (P). This configuration indicates that phosphorus has 5 valence electrons, which are distributed in the 2s and 2p orbitals.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
The electron configuration of aluminum (Al) is [Ne] 3s2 3p1
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
The element with a valence electron configuration of 2s2 is beryllium. Beryllium has 4 electrons, with 2 in the 2s subshell, which makes it have a valence electron configuration of 2s2.
The element with an electron configuration that ends with 3p is silicon, with the electron configuration 1s2 2s2 2p6 3s2 3p2.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
The element with a valence electron configuration of 3s^2 3p^4 is sulfur (S), which has 16 electrons in total.
Pretty much any element in group 15 (N, P, As) will have 2 "s" electrons and 3 "p" electrons in their valence shells, it's just that they will at different energy levels. For example, N is 2s2 2p3 and P is 3s2 3p3.
All elements in the group of Nitrogen, such as Phosphorus and Arsenic, have five valence electron when in their natural state (that is, they have not have not gained or lost valence electrons). But as to the element in that group that has valence electrons in the third electron orbital, Phosphorus is the one you are looking for. To figure this out, just look at the Periodic Table of Elements, and you will see that Phosphorus is in the third row. Hope this helps!
Lawrencium is a trivalent chemical element.
