5 days ago · Atomic number. The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z ), which is defined as the number of units of positive charge (protons) in the nucleus. For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to uranium.

1 day ago · The neutron has a mean square radius of about 0.8 × 10 −15 m, or 0.8 fm, and it is a spin-½ fermion. The neutron has no measurable electric charge. With its positive electric charge, the proton is directly influenced by electric fields, whereas the neutron is unaffected by electric fields.
2 days ago · Electromagnetism. Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, electric and magnetic circuits. The equations provide a mathematical model for electric, optical, and radio ...
4 days ago · Formal charge is a chemical measurement used to understand the way electrons are allocated throughout the molecule or the ion. Each atom in the molecule or ion has a specific charge assigned to it, helping us understand how electrons are distributed around the atom.
