- The tiny units of matter known as atoms are the basic building blocks of chemistry. An atom is the smallest piece of matter that has the characteristic properties of a chemical element, such as hydrogen, oxygen, calcium, iron, gold, and neon.

What is Atom The smallest particle that makes up all matter and yet retains the chemical properties of the element. www.survivalafterdeath.org/glossary.htm The smallest (or ultimate) particle of an element that still retains the characteristics of that element. Every atom consists of a positively charged central nucleus, which carries nearly all the mass of the atom, surrounded by a number of negatively charged electrons, so that the whole system is electrically neutral.

- 1 An atom is the smallest indivisible particle of an element which can take part in a chemical change. 2  Atoms can neither be created nor destroyed in a chemical reaction. 3  Atoms of the same element are identical in all respects, having the same size, shape and structure, and especially mass.

- There are no atoms in an atom as an atom is a small and an indivisible part of things. Inside the atoms are three parts, viz: Protons:Positively charged particles Neutrons … :Neutrally charged particles Electrons:Negatively charged particles. 1 person found this useful.

What is the difference between a compound and a molecule? What is the difference between a particle and an atom? A particle is of indeterminate size. Large 'particles' may be suspended in something like water and cause that substance to look cloudy. Smaller particles may be the subatomic… particles like protons, neutrons, and electrons that make up atoms. Different atoms have different numbers of these particles, expecially protons which determine which atom it is.

Glossary of physics The electron is a subatomic particle, symbol e− or β−, with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

What is the Difference Between an Atom and an Ion? An atom is the smallest possible unit of an element. Atoms are considered to be the basic building blocks of matter because they cannot be divided into smaller particles by any chemical process. An atom consists of three types of subatomic particles: neutrons, protons, and electrons.

- Oxygen would be (O2). The 2 is a subscript. Sub means below. The 2 is written to the right of and below the O. A pair of oxygen atoms is a molecule of oxygen. A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. Look at the model of oxygen above. The two balls represents the two oxygen molecules.

What is a proton? Atoms and Chemistry A proton is a tiny particle, smaller than an atom. Protons are too small to see, even with an electron microscope, but we know they must be there because that's the only way we can explain how atoms behave. To give you an idea how small a proton is, if an atom was the size of a football stadium, then a proton would still be smaller than a marble.

Atom Atom, from the Greek word atomos, which means indivisible, was first conceived around 2,400 years ago by a Greek man named Democritus. An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are very small; typical sizes are around 100 picometers (a ten-billionth of a meter, in the short scale).

Atom The British experimental physicist James Chadwick discovered the neutron in 1932. Of the three fundamental particles that make up atoms, the electron, the proton and the neutr … on, the neutron was the last to be discovered. It's lack of a charge made it more elusive than its companions. Links can be found below.

What is the smallest particle of an element called? A atom is the smallest neutral particle that can be identified as still that element. However, a positive ion is smaller than the neutral atom; it still has the same number of protons so it's still the element. Removal of successive electrons makes the ions still smaller.

- Answer Wiki. In ordinary matter, there are three subatomic particles: electrons, protons and neutrons. Electrons are indivisible; they are, as far as we know, dimensionless points having a [math]-1[/math] electrical charge. (I've expressed the charge in so-called natural units, where things like the
