An atom. An atom can be split into smaller pieces, but if you do that, you no longer have the same element.
No It is not true that atoms are the smallest particles in the planets. The smallest particles are electrons, protons, neutrons, and others.
Atoms are NOT the smallest particle- they are the smallest COMPLETE particle. In an atomic reaction, the atoms are broken apart, and release energy.
That depends. The smallest particle in the classic physics is te atom. In the modern physics is the quark (quark is the composition of an eletron). WHAT IS THE SMALLEST PARTICLE The quark
Atom
The number of protons determines what is the element.
The smallest particle of an element is called an atom.
An atom is the smallest particle of an element that still has the chemical characteristics of that element
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
The smallest particle of an element would be an atom. Any smaller and it would not be an element, but something more basic. Atoms are made of Protons, Neutrons, and Electrons. Protons and Neutrons are made of Quarks, Leptons, and Bosons.
This particle is called atom.
An atom is the smallest particle of an element that can be uniquely identified as that specific element.Note that this question is different from asking "What is the smallest particle in an atom?" (see related question below). Atoms are composed of smaller particles (protons, electrons, and neutrons), but the smallest thing that has the identity of a specific element is the atom.The smallest particle of an element that still retains all that element's properties is called an ATOM.
