What is the element with 16 protons?
Sulfur is a chemical element. Its official symbol is S and its atomic number is 16, which means that each sulfur atom has 16 protons in its nucleus.
What is the ion formula of phosphorus?
What is the phosphorus ion?
Phosphorus always occurs as the phosphate ion. The principal combined forms in nature are the phosphate salts.
What is the charge number of phosphorus?
(b) By referring to a periodic table or table of elements, we see that phosphorus (symbol P) has an atomic number of 15. Thus, each atom has 15 protons. The mass number of the ion is 15 + 16 = 31. Because the ion has 15 protons and 18 electrons (three more electrons than protons), its net charge is 3-.
How many electrons are present in a phosphorus 2+ atom?
