The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
The Atomic Number tells the number of protons in an atom.
The Atomic Mass number tells the atomic mass of the atom (this tells you the total number of protons + neutrons, it also tells you the mass in grams of 1 mole of the element).
The atomic number of an element is the number of protons in the atomic nuclei of that element. Each element has a unique atomic number.

The number of protons.
The atomic number of an element equals the number of protons in the element.
Silver is a metal element. Atomic number of it is 47.
An element "I.D." is an element's atomic number. An element's atomic number shows how many electrons are in an atom of that element. An element's atomic number also determins their position on the Periodic Table.
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.
The atomic number is the number of protons in an atom of an element.
Atomic number = Number of protons
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
An element's atomic number is the # of protons in its nucleus.
The atomic number tells you the number of protons in the nucleus of that element.
The atomic number of an element equals the number of protons in the element.
The atomic number of an element refers to the number of protons in the nucleus within the element. This is how the element is identified.
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.
The atomic number of an element refers to the number of protons.
The atomic number of an element refers to the number of protons.
The atomic number is the number fo protons in an atom's nucleus. It decides the element's position on the periodic table, as well as what the element is. No two elements have the same atomic number. As soon as the atomic number, or number of protons, changes, the element itself actually changes into a new element.
