We can use the information in Table 5.2 to predict the chemical properties of unfamiliar elements. They are gaseous at room temperature and chemically stable. Units. Across A Group – Across a group, valence electrons remain constant. The Group 8A elements have a full octet of eight valence electrons in their highest-energy orbitals (ns 2 np 6), so these elements have very little tendency to gain or lose electrons to form ions, or share electrons with other elements in covalent bonds. They have a strong tendency to donate their valence electron in the last shell to form strong ionic bonds. Introduction to p Block Elements. They are magnetic and boil at low temperatures. • The metallic properties of Group 6A elements increase from top to bottom within the group. Radon, helium, xenon, neon, krypton and argon are eight noble gases. They are chemically stable and liquid at room temperature. This similarity in both the composition and structure of their atomic valence shells implies a corresponding similarity in both their chemical and physical properties.
