oxygen
its the greatest part of an atom
Protons and Neutrons are found in the Nucleus of the Atom. An atom's atomic number corresponds to the amount of protons (differnt amount of protons=different element). There are usually the same amount of Neutrons and Protons, but in some cases theere are more Neutrons (these are called different isotopes).
An atom is found in matter .
The amount of protons in an atom is its atomic number
The smallest quantity of an element is an atom.
The Human Atom Bombs was created in 2001.
The nucleus can be found in the center of an atom. The electrons can be found in the 'surface' if an atom is considered to be a sphere.
A fluorine atom has the greatest electronegativity of any atom.
The total amount of protons and neutrons in an atom is its mass number.
Protons of an atom are found only in its nucleus.
Every different element has a different number of protons, that is what differentiates it from another element, so there is no answer to your question until you specify which atom you're talking about.
In an atom of an element, the amount of protons in that atom equal the amount of electrons in the atom, but only if it is a neutral atom. That then eqals the atomic number of that element.
