This would be Sulfur, which has atomic number 16. With two extra electrons it is the Sulfide anion, also called a dianion because it has charge -2.
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.
-3 like really
minus 2
-2
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- .
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.
A sulfur ion with a charge of 2- has gained 2 electrons, giving it a total of 16 protons and 18 electrons. This results in an overall charge of -2 due to the extra negatively charged electrons.
A phosphorus ion with a charge of -3 has 15 protons and 18 electrons, as the charge indicates three extra electrons. The number of neutrons can vary depending on the isotope of phosphorus.
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).

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.
A sulfur ion with a charge of 2- has gained 2 electrons, giving it a total of 16 protons and 18 electrons. This results in an overall charge of -2 due to the extra negatively charged electrons.
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.
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.
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.
A phosphorus ion with a charge of -3 has 15 protons and 18 electrons, as the charge indicates three extra electrons. The number of neutrons can vary depending on the isotope of phosphorus.
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.
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.
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).
This ion has 16 protons and 18 electrons.
16 protons and 18 electrons
