Likewise, people ask, does phosphorus have 15 or 16 neutrons?

31 – 15 = 16, so phosphorus has 16 neutrons.

In this manner, 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.

Besides, what element on the periodic table is phosphorus?

phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.

What has 15 protons and 16 neutrons?

Atomic Structure

Phosphorus has 15 protons and 16 neutrons in its nucleus giving it an atomic number of 15 and a atomic mass of 31.

What is a phosphorus atom?

Phosphorus is a chemical element with symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate. … The two most common allotropes are white phosphorus and red phosphorus.

What is mn on the periodic table?

manganese

What is the atomic structure of phosphorus?

Which isotope has 15 protons and 15 neutrons?

If there are 15 protons, 15 nuclear particles of unit positive charge, then Z=15 . Now Z≡the atomic number , and you look at your copy of the Periodic Table, and you find that for Z=15 , the element phosphorus is specified.

Why does phosphorus have an atomic number of 15?

In a neutral atom, the number of electrons are the same as the number of protons. … So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number). This isotope is phosphorus-31, which has atomic number 15.
