How an atom's electrons are organised
WebElectron configurations are a simple way of writing down the locations of all of the electrons in an atom. As we know, the positively-charged protons in the nucleus of an atom tend to attract negatively-charged electrons. While these electrons all stick within the atom because of their attraction to the protons, they also mutually repel each ... Web9 de fev. de 2016 · Note the wikipedia atomic orbitals article which says an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. Later on, the article says the electrons do not orbit the nucleus in the sense of a planet orbiting the sun, but instead exist as standing waves.

WebAtoms can lose or gain electrons due to collisions or other interactions. When they do, they form charged particles called ions: if the atom loses one or more electrons, it becomes a positively ... WebWe like representing these energy levels with an energy level diagram. The energy level diagram gives us a way to show what energy the electron has without having to draw an atom with a bunch of circles all the time. Let's say our pretend atom has electron energy levels of zero eV, four eV, six eV, and seven eV.

The charge of an electron is equal in magnitude to the charge held by a proton (but has an opposite sign). Therefore, electrically neutral atoms/molecules must have an equal number of electrons and protons. Although the magnitude of the charges held by protons and ...
WebThe electron arrangement of an atom can be predicted from its atomic number. For example, the atomic number of sodium is 11. Sodium atoms have 11 protons. and so 11 electrons:
