Question

Quizplus · Accepted Answer

The number of protons, also known as the atomic number, is unique for each element and is what determines the element's identity. The number of electrons and bonds it can form can vary depending on the chemical environment, while the number of neutrons can vary within a certain range, resulting in isotopes of the same element. The ratio of protons to electrons is always 1:1 for neutral atoms, but this is not unique to each element as many elements can have multiple isotopes.
