It highlights carbohydrates as the primary energy source, especially for athletes, and explains monosaccharides like glucose and fructose as simple sugars with unique properties. Additionally, it mentions pentoses, which are vital for the structural integrity of DNA and RNA.

The first period has only the 1s sublevel for two elements, while longer periods, like the fourth and sixth, accommodate more electrons. Understanding the sublevel filling sequence is essential for determining an element's period and block based on its electron configuration.
