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- .
The ion S(2-) 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.
Isotopes contains similar protons. So it contains 16 protons.
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).
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.
This ion has 16 protons and 18 electrons.
what element contains 16 protons? what element contains 10 protons?
'-3' It is not an atom, when it is a charged species, but an ION. 15 protons (15+) 18 electrons (18-) Hence +15 - 18 = -3 The charge. By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
16 protons and 18 electrons
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.
