This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
There are 5 valence electrons in the atom phosphorus.
The Lewis symbol for phosphorus should show 5 dots. Each dot represents a valence electron of the phosphorus atom.
5
A phosphorus atom has one nonbonding pair of electrons.
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has an electron configuration of 2, 8, 5.
4
There are 5 valence electrons in an atom of phosphorus. This is because phosphorus is in group 15 of the periodic table, which means it has 5 electrons in its outermost shell.
they all have one valence electron.
A hydrogen atom has 1 valence electron.
A phosphorus atom typically gains three electrons to achieve a stable electron configuration in an ionic bond. This allows it to attain a full outer valence shell with eight electrons, similar to the electron configuration of a noble gas.
One. A hydrogen atom contains only one electron, and it is a valence electron.
