To work out an oxidation state of an atom you need to assign the electrons on the atoms outer shell to the most electronegative atom.O>N>C>H. Electrons in the outer shell of two of the same atoms...

The atomic radius is mostly influenced by the electron cloud and its interaction with the nucleus.Along a period, the atomic number increases, which indicates that the number of electrons also increases, ...

This question tests your knowledge on weak acids, pH, Ka and equilibrium. (Note: E notation has been used, E-3 is x10^-3 ). Formic acid is a weak acid and so does not fully dissociate, the degre...

Intramolecular forces are the forces that hold atoms together or arrange atoms in specific position relative to other atoms within one molecular entity. For example, water, whose chemical...

X-ray diffraction shows all carbon-carbon bonds in benzene are the same length (140 pm), between the lengths of a single (147 pm) and double bond (135 pm). This suggests that Kekule's alternating single a...
