What is the ionic symbol for the ion that has 16 protons and 18 electrons? a. ar2+ b. s2- c. ar2- d. s2+

Option B (S ^-2) is the correct answer

Sulfur or sulfur is a chemical element with symbol S and atomic number 16. It means that it has 16 protons and 16 electrons. But when an atom of Sulfur gains two electrons, a minus 2 charge comes over it. Therefore it becomes an ion. So if it gained two electrons its electrons become 18 that is why S-2 is the correct answer.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
