YES!
This element is chlorine and is very reactive.
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
The atomic mass is determined by the neutrons and the protons, found in the elements' nucleus.

An element can be identified by the number of protons in the nucleus of its atoms.
Yes, it is the atomic number i.e. number of protons that determines an element's identity.
He determined the number of protons of the elements, which is called the atomic number.
This element is chlorine and is very reactive.
On the Periodic Table of Elements, the order from top left to bottom right is determined by the atomic number of that element, which is determined by the number of protons that are present in the nucleus of that element's atom.
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
The element won't stay the same because the element is determined by its number of protons. The number of protons is also the atomic number.
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
