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.

Ion symbol for 16 protons and 18 electrons?

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- .


What is the symbol for an ion with 16 protons 16 neutrons 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.


Indicates the number of protons and electrons for this Sulfide ion?

A sulfide ion has 16 protons and 18 electrons. The additional electron gives the ion a negative charge, making the number of electrons greater than the number of protons.


What is the number of protons and electrons in a sulfide ion -2?

A sulfide ion has 16 protons and 18 electrons. The -2 charge indicates that the ion has gained two electrons, giving it two more electrons than protons.


The net charge on a sulfur (S) ion is 2-. The ion has how many protons and how many electrons?

The ion S(2-) has 16 protons and 18 electrons.


How many electrons and protons are found in sulfur ion if the symbol for sulfur is 32 16 S2?

In a sulfur ion with a charge of 2-, there are 18 electrons (16 from the neutral sulfur atom and two additional electrons to account for the negative charge). The number of protons remains the same as in a neutral sulfur atom, which is 16.


What is the ion charge for 16 protons 18 electrons?

The ion charge for an atom with 16 protons and 18 electrons would be a 2- charge. This is because there are 16 positive charges from the protons and 18 negative charges from the electrons, resulting in a net charge of -2.


An ion that has 18e- and a net charge of plus 2?

Since the anion has a 2- charge, it must have two more electrons than protons. The number of protons is 18 - 2, which is 16. Since the element has 16 protons, it is element 16, which is sulfur (S).


What is the number of protons of sulphur?

Isotopes contains similar protons. So it contains 16 protons.


What would be the charge if an atom contains 15e and 16p?

Add up, knowing that p's are Positive and e's are nEgative: +116p(= '+') + 15e(= '-') makes (+16) + (-15) = +1So the overall charge of this 'particle' is +1(If it were a chemical particle it would have been the NON-existing S+ ion)


A sulfide ion S2- has how many protons?

A sulfide ion (S2-) has 16 protons. This is because the sulfide ion carries a charge of -2, indicating that it has gained two extra electrons, and thus has 16 protons in its nucleus as the number of protons always determines the element.


What are the number of protons neutrons and electrons in - 3 phosporus ion?

P3- has 15 protons, 16 neutrons and 18 electrons.
