1,3-butadiene, also known as buta-1,3-diene, is a molecule with the chemical formula C₄H₆. To determine the number of atoms in 1,3-butadiene, we can count the atoms of carbon (C) and hydrogen (H) present in the molecule.
In 1,3-butadiene, there are 4 carbon atoms (C₄) and 6 hydrogen atoms (H₆).
Therefore, 1,3-butadiene consists of a total of 4 carbon atoms and 6 hydrogen atoms, making a sum of 10 atoms in total.
