How did atoms form
Baryonic matter forms about 4% of the total energy density of the observable universe, with an average density of about 0.25 particles/m (mostly protons and electrons). Within a galaxy such as the Milky Way, particles have a much higher concentration, with the density of matter in the interstellar medium (ISM) ranging from 10 to 10 atoms/m . The Sun is believed to be inside the Local Bubble, so the density in the solar neighborhood is only about 10 atoms/m . Stars form fro… Webplasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states. The negative charge is usually carried by electrons, …

WebAn ion is an atom or group of atoms with a positive or negative charge. Ions form when atoms lose or gain electrons to obtain a full outer shell: metal atoms lose electrons to form... WebWhen one atom "shares" an electron with another atom to form a molecule, the atom with higher electronegativety (electron-greedy) will keep the shared electrons closer to itself than to the partner-atom. Since one atom gained an electron and keeps it near itself, the atom receives a "partial negative charge."
