How does the energy of an electron relate with the distance from the nucleus? O a. The farther a proton is from the nucleus, the greater the electron's energy. O b. The closer a proton is from the nucleus, the greater the electron's energy. O c. The closer a neutron is from the nucleus, the greater the electron's energy. Od. The farther an electron is from the nucleus, the greater its energy. e. The closer an electron is from the nucleus, the greater its energy.

Atomic Number

Elements are the building blocks of all the matter that exist in the universe. Every element is made up of atoms that have protons, electrons, and a nucleus. In order to know the difference between the elements, an atomic number is used. Every element has its own individual atomic number. The atomic number is a single most important characteristic of an atom.
