Look at the Periodic Table. You see that the element that has 16 protons is Sulfur.
Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-.
So, the symbol of the ion would be S2- .
Protons = 16 Electrons = 18
The ion S(2-) has 16 protons and 18 electrons.
P3- has 15 protons, 16 neutrons and 18 electrons.
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
It is NOT an atom but a 1+ ion of Chlorine Cl+ (atomnumber 17, massnumber 17+18=35) isotope 35.
This ion has 16 protons and 18 electrons.
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
Protons = 16 Electrons = 18
16 protons and 18 electrons
The number of protons of an element does not change when it undergoes a chemical change. It is the number of electrons that changes. Sulfur has 16 protons, and so does the sulfide ion. However, sulfur has 16 electrons, while the sulfide ion (S2-) has 18 electrons.
The ion S(2-) has 16 protons and 18 electrons.
16 protons and 18 electrons
16 protons, and if it isn't an ion ("isn't an ion" means that it has no electric charge), it has 16 electrons. on average, sulfur has 16.065 neutrons, but that's averaged out, so it's a weird number. let's just say most sulfur has 16 neutrons.
16 protons and 18 electron
i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.
P3- has 15 protons, 16 neutrons and 18 electrons.
Sulfur is a chemical element with the symbol S and atomic number 16. It has 16 protons, 16 neutrons and 16 electrons.
