WebIntroduction: When molecules of the same substance stick together, cohesion occurs. When molecules of different substances stick together, such as a drop of liquid to a solid surface,adhesion is taking place. Both cohesion and adhesion occur due to intermolecular forces of attraction. Cohesive forces tend to be stronger than adhesive forces. Webside more negative. You can think of these like magnets, where opposite charges tend to attract. This attraction is a type of intermolecular force and can be very strong. Take, for …

WebThe metal atoms are bound together by a chemical bond called metallic bonding. Metals are characterized by practically free electrons moving between the atomic ions forming a crystal lattice. In a simplistic view, the bonding is due to the electrostatic forces between the positive ions mediated by the negative free electrons.
