Why do atoms of the same element have the same chemical properties?
What are ions?
What are isotopes?
Why do isotopes of the same element have the same chemical properties but different physical properties?
What is relative atomic mass?
The average mass of an atom of an element compared to 1/12th of the mass of an atom of carbon-12.
What is relative isotopic mass?
The average mass of an atom of an isotope compared to 1/12th of the mass of an atom of carbon-12.
What is the equation to calculate the relative atomic mass?
What is the relative molecular mass ( Mr)?
