WebbHollow atoms were initially introduced as a term in surface physics by Briand et al. [ 1] in the late 1980s in order to explain the soft X-ray emission observed from the impact of 340 keV Ar ions on a gas-covered silver surface.

WebbThe valence shell is the outermost shell of an atom in its uncombined state, which contains the electrons most likely to account for the nature of any reactions involving the atom … In 1913 Bohr proposed a model of the atom, giving the arrangement of electrons in their sequential orbits. At that time Bohr allowed the capacity of the inner orbit of the atom to increase to eight electrons as the atoms got larger, and "in the scheme given below the number of electrons in this [outer] ring is arbitrary put equal to the normal valency of the corresponding element." Using these and other constraints he proposed configurations that are in accord with t… WebbCompounds Ionic & Covalent Ions and the Octet Rule Electrons in the outer most shell are called valence electrons. Calcium has two valence electrons. Atoms are most stable with 8 electrons in their outer shell — this is the octet rule. Atoms of some elements gain or lose valence electrons to obtain a full outer shell. cytonn weekly 45/2021
