Electrons are much smaller in mass than protons, only about 1/1800 of an atomic mass unit, so they do not contribute much to an element’s overall atomic mass. On the other hand, electrons do greatly affect an atom’s charge, as each electron has a negative charge equal to the positive charge of a proton.

Thus, the electron shells of an atom are populated from the inside out, with electrons filling up the low-energy shells closer to the nucleus before they move into the higher-energy shells further out.

Particles That Are Smaller Than an Atom | Sciencing
Electrons orbit around an atom’s nucleus in what is referred to as an electron cloud. The particle’s mass is tiny, approximately 1,840 times smaller than protons and neutrons. The subatomic particle has a negative charge. Electrons are primarily responsible for chemical interactions.

Electron – Wikipedia
e− or β− ) is a subatomic particle with a negative one elementary electric charge. [13] Electrons belong to the first generation of the lepton particle family, [14] and are generally thought to be elementary particles because they have no known components or substructure. [1] The electron’s mass is approximately 1/1836 that of the proton. [15]

The Size of an Electron Compared to an Atom & a Chromosome
If you add up the sizes of all the atoms in the smallest human chromosome you have 1,600,000 atoms. If they were all strung out in a line, the line would be about two-tenths of a millimeter long. That’s 20 trillion times larger than an electron. Another way of thinking of that: if an electron were the size of a grain of salt, a chromosome would …

Keiko: No, electrons and protons make up atoms—atoms are bigger than either electrons or protons. Lourdes: That’s right. Neutrons are part of atoms too. … An atom is about 10 ⁻10 m in size, while the nucleus, at 10 ⁻15 m, is 100,000 times smaller. To put this into perspective, if the nucleus were half the length of an American … lesoutrali bot
