Which shell is the valence shell for phosphorus?
1, how many valence electrons and how many core electrons does a neutral phosphorus atom have? The highest-numbered shell is the third shell, which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. That gives a total of 5 electrons, so neutral phosphorus atoms have 5 valence electrons.
How do you know how many shells an element has?
The number of electrons is equal to the atom’s atomic number, which is at the top left of the element. For example, assume you want to know how many rings are in the element neon. Neon on the periodic table has an atomic number of 10, so it has 10 electrons. Square the ring number, then multiply the result by two.

Does phosphorus have 16 neutrons?
Phosphorus also has 15 electrons. A periodic table also gives us the mass number of phosphorus (the bigger number) which is 31. This number is equal to protons + neutrons in an atom, so mass number – protons = neutrons. 31 – 15 = 16, so phosphorus has 16 neutrons.
How many neutrons do phosphorus have?
Phosphorus 32 (P-32) is the phosphorus isotope whose nucleus consists of 15 protons and 17 neutrons.
How does phosphorus have a valence of 3?
Phosphorus(Atomic no. 15) has its electrons arranged in a configuration of 2,8,5. So one can either add 3 electrons to the outer orbit or take away 5 electrons with equal ease. So Phosphorus has a valency of 3 or 5.
How does phosphorus have a valence of 5?
According to the periodic table above, phosphorus belongs to Group 5A. Therefore, Its valence electrons should be 5. The outermost orbitals, 3s2 3p3 , contains 5 electrons. Thus, valence electrons for P is 5.
How do you calculate phosphorus valency?
- The atomic number of phosphorus is 15.
- The number of electronic configuration are 2,8,5.
- When the atom gains 3 electrons the orbit is filled. or otherwise the atoms should lose 5 electrons. the valency is the combining capacity of the atom. therefore the valency of phosphorus is 3 and 5.

How do you count shells?
The chemical properties of the atom can determine by the partially filled electron which is present in the outer most shell . For example if the shell number is 1 , the maximum number of electron present in the first ‘K ‘ shell is 2(1)^2=2 .
How many electron shells does potassium have?
In the helium atom the two electrons occupy only one shell, in the chlorine atom the 17 electrons are arranged in three shells, and in the potassium atom the 19 electrons occupy four shells.
How many isotopes does phosphorus have?
There are 21 isotopes of phosphorus that are recognized(1). Phosphorus-31 is naturally occuring and is stable(2). Phosphorus-26 through 30 and phosphorus-32 through 46 are artificially produced and are radioactive(2).
Does phosphorus has a complete valence shell?
Phosphorus is in group VA so it has 5 valence electrons and Oxygen is in group VIA so each oxygen has 6 valence electrons. Total valence electrons = 5 + 4(6) = 29.
How many energy levels does phosphorus have?
there are 2 electrons at the first energy level, and 8 at the second energy level. there are 15 electrons in total, there must be 5 electrons at the third energy level. there are 3 energy levels, so the electrons at the third are outer, or valence, electrons.

How many neutrons does bromine have?
a) How many neutrons does the atom of bromine have? The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
Why phosphorus has multiple valency?
Phosphorous and Sulphur both have electrons that have entered the 3rd shell s, p, d orbitals. … It is similar in Sulphur. Thus, elements from third period onwards have multiple valency as they can form one number of bonds in non excited state and another number of bonds in excited state due to presence of d orbital.
How can phosphorus have 2 Valencies?
1) Involvement of available of vacant sub-shell in bonding. (d-orbital) : some of the elements have vacant sub-shell in same energy level. So they expand their valency and exhibit more than 1 valency in its compound. Phosphorus form PCl3 and PCl5 with chlorine.
Is the valency of phosphorus 5 or 3?
Phosphorus – Atomic number of phosphorus is 15. Its electronic configuration is 2,8,5. So, it needs 3 electrons to fulfill its outermost shell and attain stability. Thus, its valency is 3.
Why nitrogen has valency 3 and 5?
The valency of nitrogen is -3 or +5 as it has total 7 electrons so to get an inert gas configurstion or in other words to get stable it needs to gain 3 more electrons( negative sign refers to addition of more electrons ) or lose 5 electrons from its outer shell (therefore with a positive sign).
Can phosphorus lose 5 electrons?
Phosphorus tends to lose 5 electrons and gain 3 electrons to complete it’s octet.
What’s the valency of phosphorus?

Valency of Silicon | 14 | 4 |
Valency of Phosphorus | 15 | 3 |
Valency of Sulphur | 16 | 2 |
Valency of Chlorine | 17 | 1 |
What is chlorine valency?
The chlorine atom has 7 electrons in the outermost shell. Losing 7 electrons to obtain the stable electronic configuration is difficult. Instead chlorine gains one electron to achieve the octet state. Therefore, its valency is 1.
