An atom is the smallest particle of an element that still retains that element's chemical identity. In other words, one single atom of iron is still iron, but if you cut it up any farther than that, you no longer have iron, you have pieces of an atom. (There is no chemical process that can do this though.)
The word atom was introduced by a classical Greek philosopher named Democritus. Elements were also a part of ancient Greek philosophy, although Aristotle thought that there were only five of them (air, earth, fire, water, and the mysterious quintessence).
The smallest unit of every element is an individual atom.
All elements have atoms as their smallest particles.
All elements are composed of extremely small particles called atoms. Atoms are composed of protons, neutrons, and electrons.
An atom and an element are synonyms. Rather, subatomic particles make up atoms (and elements). The three types of subatomic particles are neutrons, protons, and electrons.
No. Due to the massive gravitational pull - all atoms have been reduced to major and minor subatomic particles clumped together. Therefore, there are no discernible individual atoms and hence no elements.
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
One of the best ways to describe John Dalton's observations of elements is that they are made of small particles. The atoms join in simple whole number ratios when the elements react.

Elements are made of atoms. Atoms are made of protons, neutrons, and electrons.
Elements are formed from atoms. Atoms are formed of protons, neutrons, and electrons (sub-atomic particles).
These particles are the atoms.
Atoms
Yes, everything is made of tiny particles - if it is an element then the particles are atoms of that element, if it is a compound then the particles are molecules composed of atoms of the elements which make up the compound.
the properties of elements are determined by the structures of their atoms.
You think probable to atoms.
All chemical elements (including magnesium) are formed from atoms.
atoms :) i know, i hate focus questions too :/
