Here's a breakdown of combinations of atomic numbers that add up to 200:
Understanding Atomic Numbers
The atomic number represents the number of protons in an atom's nucleus, uniquely identifying a chemical element.

Finding Combinations
To find combinations of elements whose atomic numbers add up to 200, we need to consider the atomic numbers of different elements.
Possible Combinations
- Two Elements:
- Thorium (Th, atomic number 90) + Calcium (Ca, atomic number 20) + Radium(Ra, atomic number 88) + Beryllium(Be, atomic number 4) = 200
- Three Elements:
- Lead (Pb, atomic number 82) + Gold (Au, atomic number 79) + Sodium (Na, atomic number 11) + Magnesium (Mg, atomic number 12) + Boron (B, atomic number 5) + Oxygen (O, atomic number 8) + Hydrogen (H, atomic number 1) + Hydrogen (H, atomic number 1) = 200
- Four Elements:
- Uranium(U, atomic number 92) + Platinum (Pt, atomic number 78) + Oxygen (O, atomic number 8) + Calcium (Ca, atomic number 20) + Beryllium(Be, atomic number 4) + Sodium (Na, atomic number 11) + Boron (B, atomic number 5) = 200
Note: There can be multiple combinations of elements depending on how the number 200 is split among them.
