What is the total number of electrons in the outermost shell of a phosphorus atom in ground state?

How many total and valence electrons are in a neutral phosphorus atom? A neutral phosphorus atom has

15 total

electrons. Two electrons can go into first shell, eight in the second shell, and it has five more in the third shell. The third shell is the outer valence shell, so it has 5 valence electrons.

How are 15 electrons arranged in a phosphorus atom?

A neutral phosphorus atom has 15 electrons. Two electrons can go into the 1s subshell, 2 can go into the 2s subshell, and 6 can go into the 2p subshell. That leaves 5 electrons. Of those 5 electrons, 2 can go into the 3s subshell, and the remaining 3 electrons can go into the 3p subshell.

What is neutral atom?

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore

zero

and the atom is said to be neutral.

Is phosphorus an atom or ion?

Phosphorus is a

chemical element

with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.

How do you find the number of electrons in a non neutral atom?

To determine how many total electrons there are,

add the amount of charge to the atomic number

. In this case, there are fewer protons than electrons. For example, N
^{3 –}
has a -3 charge which means it has 3 more electrons than a neutral nitrogen atom. Nitrogen’s atomic number is 7, therefore this ion has 10 electrons.

How many electrons are present in a phosphorus 3+ atom?
