In an alkene molecule with one double bond and 7 carbon atoms, there are 16 hydrogen atoms. Each carbon atom forms 4 bonds, leaving 1 bond available to form with hydrogen. With 7 carbon atoms, there are 7 double bonds, and each double bond requires 2 hydrogen atoms. Therefore, 7 x 2 = 14 hydrogen atoms are needed for the double bonds. Additionally, each carbon atom has 3 hydrogen atoms bonded to it, so 7 x 3 = 21 hydrogen atoms in total. Subtracting the 14 hydrogen atoms needed for the double bonds, we get 21 - 14 = 7 hydrogen atoms.
