Rubidium and Cesium have similar chemical properties in the ground state,the atoms of both elements each have 1.one electron in the outermost shell 2.two electrons in the outermost shell 3.one neutron in the nucleus 4.two neutrons in the nucleus. 1.The Noble Gases (Group 18) | Introduction to ChemistryThe properties of the noble gases can be well explained by modern theories of atomic structure. The outer shell of valence electrons is considered to be full in noble gases, giving them little tendency to participate in chemical reactions. It has been possible to prepare only a few hundred noble gas compounds. In the case of Neon (Ne), for example, both the n = 1 and n = 2 shells are complete and therefore it is a stable monatomic gas under ambient conditions.

The periodic table does more than just list the elements. The word periodic means that within each row, or period, the elements show a pattern of characteristics. This is because the elements are listed in part by their electron configuration. The alkali metals and alkaline earth metals have one and two valence electrons (electrons in the outer shell), respectively; because of this, they lose electrons to form bonds easily and so are very reactive. These elements comprise the s block of the periodic table.

10.1 Intermolecular Forces Chemistry

Under appropriate conditions, the attractions between all gas molecules will cause them to form liquids or solids. This is due to intermolecular forces, not intramolecular forces. Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 4 illustrates these different molecular forces. The strengths of these aSee more on opentextbc.ca
