For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble gases because of the inherent low chemical reactivity of these said gases. 5. Because of their properties, noble gases have many ...
What is the Pauli exclusion principle and what does this have to do with the chemical behavior of the elements? What do the members of the noble gas family have in common? a. They are mostly chemically inert. b. They almost never react with other elements. c. They have filled outer el...
Ionic and Covalent Bonding. » Atoms bond when their valence electrons interact ˃Atoms with full outermost energy levels are not reactive (Noble Gases) Bonding Ionic Valence Electrons The number of valence electrons in an atom of an element determines the many properties of that element, includ...
Unlike elements in groups 1A-3A, which can form cations, and atoms in groups 7A-5A, which can form anions, noble gases generally do neither. Using neon as a specific example, explain why this is so. What can be said about the ions of atoms in the s...
Metals have metallic bonds. 32. What do pure metals do? Metals have metallic bonds. 33. Metals hold onto their valence electrons very weakly 33. Metals hold onto their valence electrons very weakly. So the electrons move around the nucleus freely. ...
Step-by-Step Solution:1. Understanding Inert Gases: Inert gases, also known as noble gases, include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are located in Group 18 of
