Why do all atoms of an element have the same atomic number?
The atomic number of an element is the number of protons in its nucleus. The number of protons define what the element is.
What is the same about all atoms of one elements?
They have the same number of protons.
What does the atomic number tells you about the element?
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
