The valence electron shell of noble gases is full.
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
A filled highest occupied principal energy level
True
The electron configuration of an atom is the arrangement of electrons in the electron cloud around the nucleus of the atom. This is an indication of the different orbitals that are occupied by electrons in the atom.
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
The electronic energy band of a http://www.answers.com/topic/crystalline solid which is partially occupied by electrons.
The region surrounding the nucleus in which electrons with certain energy move is called the orbital. It refers to a bit of space where there is a 95% chance of finding an electron.
It has 2 unpaired electrons and 8 empty electron levels.
The period number tell about the energy levels occupied by electrons
Electron shells (or orbitals) are infinite. They are always there, but sometimes they are not occupied. The simplest example is the H+ ion, where hydrogen, having only 1 electron, loses it. The orbitals are still existent and are prepared to receive electrons for bonding.
one electron
they are called electron shells or sometime orbits. there are 32 electron shells. this is also called the electric cloud in the modern atomic model.
