Since water and air aren't elements, the essential element for life is Carbon.
By weight (mass), the answer would be Oxygen By number of atoms, the answer would be Hydrogen The answer could also be Carbon Take your pick

Carbon.
Earth is only one planet on solar system which has sustainable atmosphere. In other words, Earth got all the factors that can support the life. Edit: Temperature is important too, and liquid water seems to be essential.
Uonic bonds
First of all, the term you are thinking of is "essential" not assential. And water is essential to all life, also known as h20, look it up, its very interesting.

Our earth is considered as a unique planet in our solar system because of the following factors Firstly, the distance of the earth from the sun results in such a climate which is best suited for the development of man and other forms of life on earth. Secondly, it is a habitable planet it supports man and other forms of life by providing all the necessities of life. Thirdly, its atmosphere is rich in Oxygen that makes life possible on this planet. Fourthly, its atmosphere acts as a large cover to protect its surface from extreme cold and heat. Its mean temperature is 15 degree celsius, which is quite suitable for life to exist on earth. Fifthly, on this planet water occur in vast quantities which makes life possible on the earth, as water is quite essential for all forms of life.
All the bio molecules are organic compounds. Carbon is the element common among all these compounds. Carbon is a tetravalent element.
Cells. Each living organism is composed of cells, which are the fundamental units of life. Cells come in different shapes and sizes, and they perform various functions necessary for the organism to survive.
Carbon is a building block of all life and is an element that naturally occurs on this planet. There is the same volume of carbon on the planet today as their was millions of years ago.
Water! Water is a substance, not an element, but the elements that make up water are Hydrogen and Oxygen, so those elements are both essential to life. Every living thing requires water to survive. Oxygen also useful because all animals need to breath oxygen.
Another critical gas is oxygen gas (O2). Much of life on this planet is aerobic, meaning oxygen is required for survival. Oxygen serves as a key constituent in the process that releases the energy stored in food.Oxygen is not essential to all life. In fact there are some organisms that die in the presence of oxygen. There was once a time when there was no oxygen in our atmosphere and only anaerobic organisms lived. Water is essential to all known life but not oxygen.
Earth is only one planet on solar system which has sustainable atmosphere. In other words, Earth got all the factors that can support the life. Edit: Temperature is important too, and liquid water seems to be essential.
Nutrients are essential to life, and all life functions.

Phosphorus has four allotropes which have remarkably different properties. White, Red, Yellow, and Violet. It is the origin word for phosphorescence. All in all a fascinating, and dangerous element, and quite essential for life.
