The atomic number is how many protons and electrons the element has. Hope this helps!!!
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
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 atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
54 protons in the element Xenon. Xenon has an atomic number of 54 and since the atomic number= number of protons there are 54 protons in xenon.
The number of protons is the atomic number of the element.
The atomic number is the number of protons, so 15.
There are many different types of elements, all varying in the number of protons they contain. To determine the number of protons in a specific element, refer to the periodic table of elements. The atomic number (generally listed above the element's symbol, sometimes represented as 'Z') is equal to the number of protons in that atom.
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons) R
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
The number of protons is depending on to atomic number of a chemical element. Each chemical element has a specific number of protons.
