Question

Explain each of the following occurrences by referring to the structure of the atoms in question (energy levels, orbitals, protons, etc.).
a. The atomic radius of oxygen is smaller than the atomic radius of carbon.
b. The atomic radius of Mg is smaller than the atomic radius of Ca.

Answer 1

Answer:

the atomic radius of oxygen is smaller than that of atomic radius of carbon because oxygen has the the least atomic number when compared to to carbon and also because there's the proton number of protons also varies the anal three levels and orbitals energy levels s p d f also various this reason by the the magnesium is also smaller than that of radius of calcium
