Question

molecule: dopamine molecular formula: c8h11no2 how many different atoms are in your molecule? what are the different atoms in your molecule? list them below types of atoms # in molecule how many bonds are in your molecule? (count the lines in the structure)

Explanation:

Step1: Identify elements in the formula

The formula of dopamine is $C_{8}H_{11}NO_{2}$. The elements present are carbon (C), hydrogen (H), nitrogen (N) and oxygen (O).

Step2: Count number of different atoms

There are 4 different types of atoms (carbon, hydrogen, nitrogen, oxygen).

Step3: List different atoms

The different atoms are carbon, hydrogen, nitrogen, oxygen.

Step4: Count total number of atoms

For carbon: 8 atoms; for hydrogen: 11 atoms; for nitrogen: 1 atom; for oxygen: 2 atoms. Total number of atoms is $8 + 11+1 + 2=22$ atoms.

Step5: Determine number of bonds

In a molecule like dopamine, we consider the covalent - bonding nature. Each carbon atom forms 4 bonds. Hydrogen forms 1 bond, nitrogen forms 3 bonds and oxygen forms 2 bonds. Counting all the bonds in the structure (using the Lewis - structure concept), there are 32 bonds.

Answer:

• How many DIFFERENT atoms are in your molecule? 4 (carbon, hydrogen, nitrogen, oxygen)
• What are the different atoms in your molecule? Carbon, Hydrogen, Nitrogen, Oxygen
• Types of atoms in molecule: 4
• How many atoms are in your molecule? 22
• How many bonds are in your molecule? 32
