Problem 1.1 Write and compare the ground-state electron configurations for each pair of elements. (a) Carbon and silicon (b) Oxygen and sulfur (c) Nitrogen and phosphorus
The percentage of naturally occurring elements making up the human body (Carbon, hydrogen, oxygen, and nitrogen make up 96% of living matter. Most of the remaining 4% consists of calcium, phosphorus, potassium, and sulfurntages of these elements found in other organisms) are similar to the percentages of these elements found in other organisms. How could you account for this similarity among organisms
