What do atoms consist of?

Atoms consist of 3 subatomic particles: Protons, Neutrons, Electrons. Protons & Neutrons can be found in the nucleus of the atom. Outside of the nucleus is the electron cloud where all electrons are found.


Protons= positive charge

Electrons= negative charge

Neutrons= neutral

Atoms & Elements

The number of protons and electrons determines what element the atom is. An element is a basic substance that cannot be broken down any further.

Valenece Electrons?

The valence electrons are the electrons in the outer shell of an atom. The valence electrons are the ones involved in forming bonds to adjacent atoms. the amount of valence electrons also decides where the element is on the periodic table.
