The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N), which together make up about 96% of the human body. In the nonliving world, elements are found in different proportions, and some elements common to living organisms are relatively rare on the earth as a whole.
Most common elements in living things are carbon, hydrogen, nitrogen, and oxygen. These four elements constitute about 95% of your body weight. All compounds can be classified in two broad categories --- organic and inorganic compounds. Organic compounds are made primarily of carbon.
Hydrogen is the most abundant element in the universe, accounting for about 75 percent of its normal matter, and was created in the Big Bang. Helium is an element, usually in the form of a gas, that consists of a nucleus of two protons and two neutrons surrounded by two electrons.
The six common elements in all living things are carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P), and sulfur (S), often abbreviated as CHNOPS.
Carbon – 14.4kg
The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body's atoms are carbon.
Life on earth would not be possible without carbon. This is in part due to carbon's ability to readily form bonds with other atoms, giving flexibility to the form and function that biomolecules can take, such as DNA and RNA, which are essential for the defining characteristics of life: growth and replication.
4) Oxygen: The human body is composed of around $65\%$ oxygen and is the most important element for living beings. It is also present in large amounts in the atmosphere. Oxygen is dissolved in water and is present largely in this form which is helpful in the production of energy.
Carbon bonding. The carbon atom is unique among elements in its tendency to form extensive networks of covalent bonds not only with other elements but also with itself.
Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, ~70% of the Universe remains hydrogen.
The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium.
The strongest material in the universe may be the whimsically named "nuclear pasta." You can find this substance in the crust of neutron stars. This amazing material is super-dense, and is 10 billion times harder to break than steel.
Astatine is the rarest naturally occurring element.
Four elements—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up 96% of living matter. Most of the remaining 4% of an organism's weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K). Trace elements are required by an organism but only in minute quantities.
Oxygen is the most abundant element contained within living organisms, composing about 65% of the whole-body mass. Oxygen's presence within the body is essentially stored in the form of water molecules, which is employed to supply the energy within the body needed to sustain life.
The Elements: An Introduction. The wisdom gleaned from the natural elements—fire, earth, air, and water—is a foundation of healing practices in Chinese, Native American, Vedic, and Tibetan cultures.
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
Technetium, promethium, astatine, neptunium, and plutonium were discovered through synthesis before being found in nature.
By mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent).
The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulphur and phosphorus.
It would be impossible for life on earth to exist without carbon. Carbon is the main component of sugars, proteins, fats, DNA, muscle tissue, pretty much everything in your body. The reason carbon is so special is down to the electron configuration of the individual atoms.
Diamond is composed of the single element carbon, and it is the arrangement of the C atoms in the lattice that give diamond its amazing properties.
About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.
