What are elements essential to life?
The four basic elements of life are: Oxygen, hydrogen, nitrogen and phosphorus. These four elements are found in abundance in both the human body and in animals. There are other elements that compose the human body, but the four we’ve highlighted participate in all life processes.
What are the 10 elements that are essential to life?
The essential mineral elements are: Nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel.
What is the 21 elements essential for life?
The 21 elements directly essential to human life, either as macronutrients (relatively large amounts, measured in milligrams) or micronutrients (small amounts, measured in micrograms), are as follows: calcium, carbon, chlorine, chromium, cobalt, copper, fluorine, hydrogen, iodine, iron, magnesium, manganese, molybdenum …
What is the atomicity of elements?
Atomicity is defined as the total number of atoms present in a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms. Some authors also use the term to refer to the maximum number of valencies observed for an element.
What are the 4 basic elements?
The Four Elements. Greek philosophy supposed the Universe to comprise four elements: Fire, Water, Earth, and Air.
What are the 17 essential elements?

What are the 7 elements of life?
The seven Elements are Nature, Water, Fire, Earth, Light, Darkness, and Spirit.
What is atomicity example?
Atomicity can be defined as the total number of atoms that composes a molecule. Simply put, it is the no of atoms present in a molecule. For example, each molecule of oxygen is composed of two oxygen atoms. So atomicity of oxygen is 2.
Why is the atomicity of sodium 1?
We know that an atom consists of a nucleus which is much smaller in size than the atom. We know that the element sodium has atomic number 11 and the element exists as Na atoms only they do not exist as molecules. So we could say that the atomicity of sodium is 1 i.e. sodium is a monatomic molecule.
