Chemistry Class 11 Chapter 5 Atomic Structure

The atom is a basic unit of matter that consists of a central nucleus surrounded by a cloud of negatively charged electrons. Positively charged nucleus is surrounded and neutralized by negatively charged electrons revolving in orbits at varying distances from the nucleus. The electrons in atoms are structured as shells. The outer shell is the one involved in molecular structure. Dipole-dipole interactions are weaker than London forces? Boiling points depend on the polarizability? Ethyl alcohol is soluble in water due to hydrogen bonding? Ice is good conductor of heat and electricity? Evaporation does not depend on surface area?
