The element is phosphorus and it contains 5 valence electrons.
Six.
There would be 8 valence electrons.
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Electrons in the outermost energy shell (valence shell) have the most energy.
A neutral atom of magnesiumhas two electronsin its outermost energy level

Six.
All neutral carbon atoms have 6 protons and 6 electrons, regardless of isotope. From the periodic table, the atomic number of carbon is 6, and atomic number is the number of protons in the nuclei of a given element's atoms. In a neutral atom, the number of positively charged protons is equal to the number of negatively charged electrons.
There would be 8 valence electrons.
Phosphorus has five electrons in its outermost energy level (valence electrons).
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
valence electrons are the electrons in the outermost energy level
Outermost have more energy than innermost. As electrons move inward, they release energy.
Electrons in the outermost energy shell of an atom are called valence electrons.
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
Halogens have six valence electrons in the outermost energy level.
