Atoms are the foundation of the chemistry, they are the basis for every thing in the Universe. Matter is made as you know of atoms. Solids are made of atoms densely packed, and gases have atoms that are spread out.
The parts of an atom.
The atoms have three tiny parts, they are called: electrons, protons and neutrons.
What are the electrons, protons and neutrons?
What are the electrons?
Electrons are the tiniests of the three particles that form up an atom. Electrons are in the orbitals that is surronding the nucleus of an atom. Electrons have a negative charge.
What is the nucleus?
The nucleus is the the thing that is in the midle of an atom. The nucleus its form with the protons and the neutrons. We can´t forget that neutrons haven´t got any charge, but proton have a positive charge.
This is a table with the charges of the three parts of an atom (electrons, protons and neutrons):
