The heaviest atom naturally found on Earth is uranium.
Uranium has an atomic number of 92, meaning it has 92 protons in its nucleus. The more protons an atom has, the heavier it is.
While heavier elements exist, such as Oganesson (atomic number 118), these are synthetically produced and not found naturally.
Here are some key points to remember:
- Atomic number determines the number of protons in an atom's nucleus.
- Protons are positively charged particles that contribute to an atom's mass.
- Heavier atoms have more protons and therefore more mass.
