The number of protons is the "atomic number", so you look that up in the Periodic Table.
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
The number of protons is equal to atomic number and the number of electrons (for a neutral atom).
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
The protons don't change because if the number of protons changes, the type of element the atom is changes. The number of protons determine the species of the atom.
He determined the number of protons of the elements, which is called the atomic number.
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
The atomic number is equal to the number of protons.
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
The identity of an element is determined by the number of protons.
The number of protons is equal to atomic number and the number of electrons (for a neutral atom).
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
The number of protons in a nuclide is the atomic number for that element on the periodic table.
Number of protons or the atomic number of an atom determines what is the element.
The atomic number of an element is determined by the number of protons.
Calcium has 20 Protons. You can determine the amount of Protons in an Element by checking the top number of an element. This is called the Atomic number. Calcium has 20 protons
