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.
Isotopes contains similar protons. So it contains 16 protons.
Sulfur's atomic number is 16. Therefore, neutral sulfur has 16 protons and 16 electrons. Since we're dealing with S2-, we need to add 2 electrons to that, giving 18 total.
No, Sulfur has 16 protons, and Iodine has 53. So that means that Iodine has more protons than Sulfur.
12 electrons, 12 protons, and 16 neutrons
Potassium oxide is K2O.It has 46 protons and 46 electrons (19 + 19 + 8 = 46).If the most stable isotope of K and O are used (K-39 and O-16), then there will be 48 neutrons (20 + 20 + 8 = 48).So the total number of sub atomic particles will be 140(46 protons + 46 electrons + 48 neutrons).
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- .
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.
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.
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 ion S(2-) has 16 protons and 18 electrons.
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.
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.
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).
Isotopes contains similar protons. So it contains 16 protons.
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 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.
P3- has 15 protons, 16 neutrons and 18 electrons.
