Answer:
Length of whale in km = 0.028578 km
Explanation:
Given:
Length of whale = 28,578 millimeter
Find:
Length of whale in km
Computation:
We know that;
1 km = 1,000,000 mm
So,
Length of whale in km = 28,578 / 1,000,000
Length of whale in km = 0.028578 km

Every period of time, the radioactive isotopes halve in numbers as they emit radiation.
I think you now know the gist. Try doing the rest yourself.
Good luck.
Answer:
Noble gases
Explanation:
The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.
The reason for this difficult is that their electronic configuration confers a stable configuration them.
- The ionization energy is the energy required to remove the most loosely held electrons in an atom.
- Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.
