What is the Lewis dot structure for CH2O ? Lewis Structure: The first step towards writing the Lewis structure of a molecule is to arrange the constituent atoms according to the structure of the molecule. In case of simple covalent molecules, if only the molecular formula is known, then the...
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
