When answering these questions just refer to the Periodic Table. Nitrogen is in the 5th column (excluding the d block) This means that Nitrogen has 5 valence or outer electrons (free electrons) I am assuming that you are referring to N2. NOTE we always want to achieve the stable 8 electron configuration but this cannot always happen. In the case of N2 this is possible since we have 2 N's therefore we have 2 x 5 electrons=10 we can have single double and triple bonds. single has 2 electrons double has 4 electrons triple has three therefore for each N to have 8 electrons (the stable number) :N(three lines)N: hence 2x2+3x2=10 so we are right this is the electron configuration.
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 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.
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
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 valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
The electron configuration of phosphorus is [Ne]3s2.3p3.
Krypton has 8 valence electrons.The electron configuration is: [Ar]3d10.4s2.4p6.
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 electron configuration of aluminum (Al) is [Ne] 3s2 3p1
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê

The valence electron configuration of oxygen is 2s2 2p4. Oxygen has 6 valence electrons in total, with 2 in the 2s orbital and 4 in the 2p orbital.
To determine the number of valence electrons in an atom using its electron configuration, look at the highest energy level (n) in the electron configuration. The number of electrons in this energy level is the number of valence electrons.
