The document provides an overview of isotopes, highlighting their differences from atoms, specifically regarding neutron and proton counts. It explains relative atomic mass as the average mass of an element's isotopes, emphasizing the significance of abundance in this calculation. Additionally, it includes a visual representation of the three isotopes of hydrogen.

2. Today we are going to learn about
isotopes and how they are different
from atoms. we are also going to
learn about relative atomic mass
and how it is calculated.

3. Isotopes are atoms that have a different
number of neutrons but same number of
protons, causing them to have a different
mass number. some elements have multiple
isotopes that occur naturally and isotopes
are generally named as the name of the
atom followed by the mass number of the
isotope

4. This image shows us the
atomic structure of the three
isotopes of hydrogen. What
are the similarirties and
differences between them?

6. RELATIVE ATOMIC
MASS
Relative atomic mass or atomic
weight is the average of the
masses of the elements
isotopes. The abundance of an
element and its isotopes play an
important role in calculating
relative atomic mass.
