Still, many scientists disagree with the new evidence. Instead, they attribute the gecko’s defiance of gravity to intermolecular forces instead of electricity. 14. Appliances Don’t Consume Electricity When They’re Off Have you ever wondered how birds can relax on electric wires without ever get...
Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. Learn more about the properties and structures of molec
TheTable lists the important properties of molecular hydrogen, H2. The extremely low melting and boiling points result from weak forces of attraction between the molecules. The existence of these weak intermolecular forces is also revealed by the fact that, when hydrogen gas expands from high tolow...
This is because of something called surface tension, which is an imbalance of intermolecular attractive forces. This can also occur in low Earth orbit. Mercury, Venus, Earth & Mars are known as the “Inner Planets”. They are named the Inner Planets because they orbit closest to the Sun. A...
Particles of a gas are widely spread out from one another, almost like there are no intermolecular forces binding them together. Just like liquids, gases have no regular arrangement, and particles can move freely and at high speeds. Due to this, gases exhibit the following characteristics: ...
Crystals have regular ordered arrays of components which are held together by uniform intermolecular forces. The components of a solid can only be arranged in two (2) different ways: (1) in a way where they form regular repeating three dimensional structures called a crystal lattice which produce...
Intermolecular hydrogen bonding of similarly oriented ribopyranose molecules in DL-ribose II at 295 K, and D-ribose polymorphs at 123 K: Form I contains two independentA,Bpyranose molecules and form II three disordered anomersA,B,C. Full size image ...
2Intermolecular Forces Molecules in a compound exert an attractive force on each other. Eventually, the attractive forces overpower the energy of the fluid motion of molecules. The molecules bond together, and the substance takes on the rigid shape of a solid. The total intermolecular force between...

In the solid state (ice), intermolecular interactions lead to a highly ordered but loose structure in which eachoxygenatomis surrounded by fourhydrogenatoms; two of these hydrogen atoms are covalently bonded to the oxygen atom, and the two others (at longer distances) are hydrogen bonded to the...
