Phosphorous
The electronic structure 2.5 suggests that the element has 2 electrons in its first energy level and 5 electrons in its second energy level. This corresponds to the element with an atomic number of 7, which is nitrogen (N). Nitrogen is located in group 15 of the periodic table and is essential for life, being a key component of amino acids and nucleic acids.
beryllium
The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.
On the periodic table, for each element there is a column of 1 to 7 numbers on the right side, these numbers show the number of electrons in each shell, or layer, The bottom number is the number of electrons in the outermost layer
Elements with five electrons in the highest energy p sublevel in their ground state are referred to as Group 15 elements. The p sublevel is the third energy level, and these elements are known as the nitrogen group. Examples include nitrogen (N) and phosphorus (P).
Nitrogen.
Outer electrons, or Valence Electrons, for nitrogen is 5 electrons. The first electron level requires 2 electrons, an electron pair, to fill it and move on to the next level. Nitrogen has 7 electrons, so 7-2=5.
It would be 3 electrons!Why?Antimony: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p3 Nitrogen: 1s2,,2s2,2p3Phosphorus: 1s2 2s2 2p6 3s2 3p3Arsenic: 3d10 4s2 4p3Bismuth: 4f14 5d10 6s2 6p3so on..
chlorine
The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
beryllium
Nitrogen has 7 electrons in total. In its ground state, nitrogen has two electrons in the 1s orbital and five electrons in the 2p orbital. Therefore, there are 3 electrons in the higher energy level (2p orbital) of nitrogen.
7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
5, it is the number of valance electrons determined by the roman numeral over the group in the periodic table of elements
The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.
An element's group is determined by its location on the periodic table. Elements within the same group share similar chemical properties and have the same number of valence electrons. The group number corresponds to the number of valence electrons an element has in its outermost energy level.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
