All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
The atomic number indicates the number of protons an atom has and in a neutral atom, also the number of electrons. It thus indicates where on the Periodic Table the element can be found and the manner in which the element will behave.
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
It tells you the number of Protons in the nucleus of the atom
The atomic number of an element refers to the number of protons.
The element with the atomic number 15 is Phosphorus.
The atomic number for the Element Lead is 82.
No element has this atomic number. All atomic numbers are whole numbers.
Silicon is a non meta element. Atomic number of it is 14.
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 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.
The atomic number of an element refers to the number of protons.
The atomic number of an element refers to the number of protons.
