How to Draw Lewis Dot Structures? (with examples)
Lewis Dot structure is a representation of how electrons are arranged in a molecule. To correctly draw lewis dot structures we need to follow the following six steps. 1. Calculate the total number of valence electrons 2. Connect atoms in a molecule using bonds 3. Subtract electrons used in bonds from the total electrons calculated in part 1 4. Use remaining electrons to make outer atoms happy (octet, 8 electrons) but remember that Hydrogen only wants 2 electrons. 5. If there

The only two elements in alkenes and alkynes are
The only two elements in alkenes and alkynes are (1) carbon and nitrogen (2) carbon and hydrogen (3) oxygen and nitrogen (4) oxygen and hydrogen Answer: (2) carbon and hydrogen Explanation: If we look at the Chemistry Regent Reference table, we will see on Table Q, that alkenes and alkynes belong to the Homologous Series of Hydrocarbons. Hydrocarbons are organic molecules that contain carbon and hydrogen. Therefore, they must have the elements of hydrogen and carbon, making c
