orbitals, each of which can hold 2 electron of opposite spin.
electron shells
Electron shells, orbitals, and sub-orbitals.
Electrons occupied certain discrete energy levels around the nucleus.
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.
In reality, the electrons are on different energy levels at different distances in a sort of cloud around the nucleus. Traditionally, this is simplified and drawn as a series of 'rings' at different distances from the nucleus.

Electrons are organized in atoms into specific energy levels or shells, which are further divided into sublevels and orbitals. The arrangement follows the principles of quantum mechanics, with electrons occupying the lowest available energy states first (the Aufbau principle) and adhering to the Pauli exclusion principle, which states that no two electrons can have the same set of quantum numbers. The organization of electrons determines an element's chemical properties and its behavior in bonding and reactions.
This is a description of the electron transport chain, which is part of cellular respiration in eukaryotic cells. It involves a series of protein complexes located in the inner mitochondrial membrane that transfer electrons and pump protons to generate ATP. This process is essential for producing energy for the cell.
An activity series is a list of elements organized according to the ease in which an element can undergo certain chemical reactions.
