Electrons occupied certain discrete energy levels around the nucleus.
electron shells
electrons in magnets are organized and generally pointing in the same direction
Electrons are generally gathered around an atom beginning with the lowest possible quantum numbers.
Electrons occupied certain discrete energy levels around the nucleus.
orbitals, each of which can hold 2 electron of opposite spin.
Electron shells, orbitals, and sub-orbitals.
They are organized by atomic number (the number of protons/electrons in the element).
An atom is organized with a nucleus at its center, containing protons and neutrons. Electrons orbit the nucleus in specific energy levels or shells. The nucleus is positively charged, while electrons are negatively charged, creating a stable, neutral atom.
Electrons collect in the outer energy levels of atoms, known as electron shells. These shells are organized around the atomic nucleus and can hold a specific number of electrons based on the atom's atomic number and electron configuration.
1) atomic number (number of protons) 2) valance electrons
The modern periodic table is arranged in the increasing order of their atomic number and repeating properties. The elements in the same family / group have the same number of valence electrons.
Electrons are basically surrounding the nucleus (containing the protons and the neutrons), and are "swirling" around the nucleus, forming a cloud like shape around the nucleus.
