Question

is the study of organic compounds—the compounds that contain carbon. in the figure below, notice that carbon has four electrons in its outer energy level. recall that the second energy level can hold eight electrons. therefore, a carbon atom can form four covalent bonds with other atoms. carbon atoms can bond with each other, forming a variety of organic compounds. these organic compounds can take the form of straight chains, branched chains, and rings, as illustrated in the figure below. carbon compounds are responsible for the diversity of life on earth. take a look 1. calculate what percentage of the carbon atom’s second energy level is filled?

Explanation:

Step1: Identify the number of filled electrons and total capacity

The carbon atom has 4 electrons in its second - energy level, and the second - energy level can hold 8 electrons.

Step2: Use the percentage formula

The percentage formula is $\text{Percentage}=\frac{\text{Number of filled electrons}}{\text{Total capacity of the level}}\times100\%$. Substitute the values: $\text{Percentage}=\frac{4}{8}\times100\%$.

Step3: Calculate the result

$\frac{4}{8}\times100\% = 50\%$.

Answer:

50%
