Steps for Writing the Molecular Formula of Straight Chain Alkanes. A molecular formula tells us the number of atoms of each element present in a molecule of the compound. For an alkane, only two elements are present, carbon (C) and hydrogen (H). When writing the molecular formula of an alkane, the number of carbon atoms is written before the number of hydrogen atoms, that is, C is written.

Bookmark; Glossary Terms; An updated version of the Chemical Bonding module is available. To view it, go here. Though the periodic table has only 118 or so elements, there are obviously more substances in nature than 118 pure elements.This is because atoms can react with one another to form new substances called compounds (see our Chemical Reactions module).
