The smallest unit of an Element that maintains the properties of the element is an Atom of that element. Y (Yttrium). Consequences: There is not regular trend in ionization potential in the group due to lanthanide contraction. In the same year, Bartlett established that it is indeed possible to remove electrons from xenon by chemical means. The 5S2 means there are two electrons in the S orbital, which is the first energy level. Screened from the nucleus by intervening electrons, the outer (valence) electrons of the atoms of the heavier noble gases are held less firmly and can be removed (ionized) more easily from the atoms than can the electrons of the lighter noble gases.
