Phosphorous
29 electons in its outer shell.
phosohorous
Any group 5 element
beryllium
The number of electrons it has in the highest occupied energy level.
An atom with 5 electrons in its second energy level will form 3 covalent bonds. These atoms are "trivalent." Nitrogen, for example, has 7 electrons, two in the first energy level, and five in the second. There are 3 bonding pairs of electrons and one set of unpaired electrons. Ammonium (NH3+) is one example.
You can determine the number of electrons in the outer level by the goup numbers. Like aluminum (atomic number 13) will have three in the outer level. There will be two in the first inner level. in the second level there will be eight. and in the last three.
Nitrogen.
chlorine
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..
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.
Any group 5 element
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
5 valence electrons.
Nitrogen has five electrons on the outer level.
beryllium
There are 3 valence electrons in the highest energy level of Nitrogen. Nitrogen has a total of 5 valence electrons.
The number of electrons it has in the highest occupied energy level.
Mg(K,L,M)= 2, 8, 2
