The elements that have least protons to those having the most protons in the atoms are:
B. C, Al, P, Cl
Protons in an atom:
There is an equal number of protons and electrons in an atom. So when moving across a period in a periodic table the number of electrons increases which also shows the increases in a number of protons. So as the atomic number increases, the number of protons and electrons also increases.
Thus, the order of elements having least to greatest protons are:
C, Al, P, Cl
C has 6 atomic number, Aluminium has 13 atomic number , Phosphorus has 14 atomic number and atomic number of chlorine is 17.
Thus, option B is correct.
