The particles we're made of About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life.

In summary, for a typical human of 70 kg, there are almost 7*10^27 atoms (that's a 7 followed by 27 zeros!) Another way of saying this is "seven billion billion billion." Of this, almost 2/3 is hydrogen , 1/4 is oxygen , and about 1/10 is carbon .

Almost 50% 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.

If so, what differentiates us from non living things? Yes, cells are made up of atoms. However, the kinds of atoms that make up cells combine chemically to create particular molecules.

We're made of cells and cells are made of proteins and proteins are made of amino acids. ... Amino acids, like all molecules, are made up of atoms.

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

What is an atom? ... Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons.

Atoms are the smallest and most basic units of matter that have the properties of an element. All atoms have the same basic parts (electrons, protons, and neutrons), but they are arranged in different ways.

An atom is the smallest particle of an element that still has elemental properties. Atoms are made up of similar properties called protons, neutrons, and electrons. The smaller electrons orbit around a central nucleus of protons and neutrons. Atomic number. The number of protons in the nucleus of an atom.

An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium.

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

But physicists now know that atoms are not solid little balls. It's better to think of them as tiny electrical, “planetary” systems. They're typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system.

Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. ... Neutrons have no charge. Since opposite charges attract, protons and electrons attract each other.

Energy! At a pretty basic level, we're all made of atoms, which are made of electrons, protons, and neutrons. ... A lot of scientists think that almost all the mass of our bodies comes from the kinetic energy of the quarks and the binding energy of the gluons.

We are all made of stars: half our bodies' atoms 'formed beyond the Milky Way' Nearly half of the atoms that make up our bodies may have formed beyond the Milky Way and travelled to the solar system on intergalactic winds driven by giant exploding stars, astronomers claim.

How many elements are there? An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is.

In summary, for a typical human of 70 kg, there are almost 7*1027 atoms (that's a 7 followed by 27 zeros!) Another way of saying this is "seven billion billion billion." Of this, almost 2/3 is hydrogen, 1/4 is oxygen, and about 1/10 is carbon. These three atoms add up to 99% of the total!
