English: Diagram of an idealized Lithium atom, primarily useful to illustrate the nucleus of an atom. This sort of design is scientifically inaccurate in many important respects, but serves as a powerful mandala of the nuclear age. Inspired by drawing from User:Fastfission, recreated by User:AG Caesar in vector/svg format.
If an atom has more electrons than protons, then it has an overall negative charge and is called a negative ion (or anion). Conversely, if it has more protons than electrons, it has a positive charge and is called a positive ion (or cation). The electrons of an atom are attracted to the protons in an atomic nucleus by the electromagnetic force.
The chemical element of each atom is often indicated by the sphere's color. [2] In a ball-and-stick model, the radius of the spheres is usually much smaller than the rod lengths, in order to provide a clearer view of the atoms and bonds throughout the model.
Wilayah berwarna cokelat menjodohkan boson (merah) dengan fermionnya (ungu dan hijau). Harap perhatikan bahwa massa beberapa partikel bisa berubah sesuai hasil evaluasi para ilmuwan. Nilai yang dipakai diagram ini berasal dari data tahun 2024 dan mungkin sudah diubah sejak saat itu.
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.

A given atom would have solid and hollow valence spikes. The solid rods clicked into the tubes forming a bond, usually with free rotation. These were and are very widely used in organic chemistry departments and were made so accurately that interatomic measurements could be made by ruler.
A Grotrian diagram of the hydrogen atom. Only transitions between adjacent columns are allowed, as per the selection rule =. A Grotrian diagram, or term diagram, shows the allowed electronic transitions between the energy levels of atoms. They can be used for one-electron and multi-electron atoms.
