Hydrogen, ammonia, methane and pure water are also simple molecules. All have strong covalent bonds between their atoms, but much weaker intermolecular forces between molecules. When one of these ...

Atoms involved in covalent bonds can be the same element or different elements. For example: In a water molecule (H2O), two hydrogen atoms and one oxygen atom form covalent bonds by sharing electrons.

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two.

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus ...
