What elements account for 95 percent of your body weight?
The elements that make up 95% of the human body are oxygen, carbon, hydrogen, and nitrogen. These elements are essential for building molecules like proteins, carbohydrates, lipids, and nucleic acids that are vital for the structure and function of our cells.
Which two elements are the most abundant in the earths crust?
Oxygen and silicon are the two most abundant elements in the Earth's crust. They make up about 75% of the Earth's crust by weight.
Why atomic weight of chlorine is 35.5 though isotopes of chlorine 35 and 37?
The atomic weight for each element on the periodic table represents a weighted average of the masses of all naturally occurring isotopes of an element. Because of this, the elements do not have whole-number atomic weights. An exception is the atomic weight for some elements written inside parentheses. These elements do not have stable isotopes and the atomic weight listed is the atomic weight for the longest lived isotope.
How can one determine the atomic weight of an element?
The atomic weight of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This information is typically found on the periodic table of elements.
Which elements make up 98 percent of most organisms body weight?
The most common elements that make up 98% of an organism's body weight are oxygen, carbon, hydrogen, and nitrogen. These elements are essential for building organic molecules such as carbohydrates, proteins, lipids, and nucleic acids that are crucial for life.
