An element is a substance that is composed of atoms that are all of one type. Every atom, in turn, consists of at least two types of particles, protons and electrons. All of the atoms in a sample of an element have the same number of protons in them.
It's a lot more complicated than this but this is a good start.
The smallest particle of an element is called an atom.
a quark or if you mean the smallest element hydrogen
This particle is the atom.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
An atom is the smallest particle that is still recognisably the element
The smallest particle in the atom is the electron.
The smallest particle of an element that has the properties of that element is called an atom.
Atom
This particle is called atom.
The smallest particle of an element that still retains the chemical characteristics of that element is called an atom. Each element is made up of atoms, which are composed of protons, neutrons, and electrons.
The smallest particle of an element in chemistry is an atom. Atoms are made up of protons, neutrons, and electrons.
An atom of iron is the smallest particle of the element iron.
