The atomic number in an element is equal to the number of protons in an element. For example, Hydrogen has an atomic number of 1 and 1 proton.
It is equal to the no. of electrons in the atom. It is called the atomic number.
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).
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
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 number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
The number of protons in the nucleus of of the element. For Plato Its C :)
The atomic number is equal to the protons and electrons of an element.
The number of protons, electrons, and neutrons:P
The atomic number is equal to the number of protons.
It is equal to the no. of electrons in the atom. It is called the atomic number.
In an atom, the number of protons is the same number as the atomic number.
The number of protons is equal to the atomic number of a chemical element.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
The number of protons is equal ti the number of electrons. Yttrium is the element. It is in the d block.
The Atomic Mass is equal to the number of protons and electrons that an element has.
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.
