That is chlorine and it has seven valance electrons.
The electron configuration is gallium, which has 3 valence electrons so I think it's three.
Valence electrons refer only the those electrons in the OUTERMOST shell. In the case shown, that would be the 3rd shell which has 3s2 and 3p1 for a total of 3 valence electrons.
You think probable to chromium.
Manganese i pretty sure
It has just one valence electron.

The electron configuration of sulfur is [Ne) 3s2.3p4.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
Ra, radium
Phosphorus has the above electron configuration. It has 15 electrons and protons.
the element is tungsten with the electronic configuration Xe 4f14 5d4 6s2
The electron configuration of hassium is: [Rn]5f14.6d6.7s2.
The electron configuration of the element with the atomic number 39 (yttrium) is: [Kr]4d15s2.
The element with that electron configuration is Iron.
The electron configuration of sulfur is [Ne) 3s2.3p4.
If you mean 1s22s22p3, you would refer to the periodic table. Using 2p3, you would look at the second period (row), look at the p block, and count 3 elements to the right to find nitrogen.
Sulfur (S) has the electron configuration 1s22s22p63s23p4.
1s2 2s2 2p6 3s2 3p3 is the electron configuration of element 15.
The electron configuration of americium is [Rn]5f7.7s2.
The electron configuration of phosphorus is [Ne]3s2.3p3.
[He] 2S2 is the noble gas electron configuration for beryllium.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
