Selenium forms covalent bonds.
The sulfur atom only has 6 electrons in its outer shell, and following the octet rule, it wants to get to the closest noble gas. The elements want to have a full outer level, so it will gain 2 electrons to get to 8. So the Sulfur atom now becomes a Sulfide ion.
A sulfur atom becomes a sulfur ion by losing or gaining electrons. If a sulfur atom loses electrons, it becomes a positively charged sulfur ion (sulfur cation). If it gains electrons, it becomes a negatively charged sulfur ion (sulfur anion).
The sulfide ion (S²⁻) has 16 protons and 18 electrons. This is because the element sulfur (S) normally has 16 protons and 16 electrons, but by gaining two extra electrons to achieve a stable electron configuration, it becomes the sulfide ion with 18 electrons.

The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom. This extra repulsion in the sulfide ion increases the average distance between the valence electrons, so the electron cloud around the sulfide ion has the greater radius.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
It becomes this ion after the gain of two electrons.
The sulfur atom only has 6 electrons in its outer shell, and following the octet rule, it wants to get to the closest noble gas. The elements want to have a full outer level, so it will gain 2 electrons to get to 8. So the Sulfur atom now becomes a Sulfide ion.
It becomes a sulfur ion with a charge of -2.
A sulfur atom becomes a sulfur ion by losing or gaining electrons. If a sulfur atom loses electrons, it becomes a positively charged sulfur ion (sulfur cation). If it gains electrons, it becomes a negatively charged sulfur ion (sulfur anion).
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
When a sulfur atom gains two electrons to become a sulfide ion, it achieves a stable electron configuration with a full valence shell. This results in the formation of a negatively charged ion with a 2- charge. A sulfide ion forms due to electron transfer, creating a more stable configuration for the sulfur atom.
An atom of sulfur-36 can gain two electrons to become a sulfide ion with a -2 charge. When it gains these two electrons, it achieves a stable electron configuration, similar to the noble gas configuration of argon, resulting in a charge of -2.
The symbol for a sulfur atom that has gained 2 electrons is represented as S^2-.
A sulfur atom can gain two electrons to form the sulfide ion, S^2-. In this process, the sulfur atom gains electrons and becomes negatively charged. It does not lose any protons or neutrons in this process.
Sulfide anion is formed which can be represented as S2-.
A sulfide ion, S2-, has 18 electrons. A neutral sulfur atom has 16 electrons, the same as the number of protons, which is the atomic number. Since electrons have a negative charge, a sulfur atom must gain two extra electrons in order to form the sulfide ion with a charge of 2-.
