2 days ago · Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium ...

A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]
3 days ago · In quantum mechanics, an atomic orbital ( / ˈɔːrbɪtəl /) is a function describing the location and wave-like behavior of an electron in an atom. [1] . This function describes the electron's charge distribution around the atom's nucleus, and can be used to calculate the probability of finding an electron in a specific region around the nucleus. [2]
5 days ago · Atomi su u električno neutralnom stanju ako imaju isti broj protona i neutrona. Atomi koji imaju višak ili manjak elektrona nazivaju se ioni . Elektroni koji se nalaze najdalje od jezgra mogu preći na druge susjedne atome ili ih dva atoma mogu dijeliti kao zajedničke.
