In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
The motion of water molecules at room temperature and their transient interactions with each other. Ball-and-stick models can be physical artifacts or virtual computer models. The former are usually built from molecular modeling kits, consisting of a number of coil springs or plastic or wood sticks, and a number of plastic balls with pre ...

The simple MO diagram of H 2 O is shown on the right. [2] [3] Following simple symmetry treatments, the 1s orbitals of hydrogen atom are premixed as a 1 and b 1. Orbitals of same symmetry and similar energy levels can then be mixed to form a new set of molecular orbitals with bonding, nonbonding, and antibonding characteristics. In the simple ...
Water – chemical substance with the chemical formula H 2 O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions , but it often co-exists on Earth with its solid state, ice , and gaseous state ( water vapor or steam ).
In chemistry, a water cluster is a discrete hydrogen bonded assembly or cluster of molecules of water. [ 1 ] [ 2 ] Many such clusters have been predicted by theoretical models ( in silico ), and some have been detected experimentally in various contexts such as ice , bulk liquid water, in the gas phase , in dilute mixtures with non-polar ...
Water (H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue.It is by far the most studied chemical compound [20] and is described as the "universal solvent" [21] and the "solvent of life". [22]
Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.
