Among the elements Ca, Mg, P and Cl, the order of increasing

(a) Ca < Mg < P < Cl (b) Mg < Ca < Cl < P
(c) Cl < P < Mg < Ca (d) P < Cl < Ca < Mg

Answer:
c
Explanation:
- Ca is largest because from top to bottom in periodic table size increases and from left to right atomic size decreases because . from top to bottom electron is added in different n levels , from left to right electron is added in the same n level
- as cl belong to halogen which is right corner and top so it is small in size
- similarly with mg and p

Ca, Mg, P and Cl, the order of increasing atomic radii is Cl < P < Mg < Ca.
Explanation:
Atomic radius
- Size of its atom is measured by the atomic radius of the chemical elements. Typical interval from the center of the nuclei through the boundary of the electron shell surrounded.
- From left to right over a period it decreases the atomic radius. Nitrogen radius slightly less than the oxygen radius. Addition of protons in the nucleus and electrons are added to the equal energy level, within a period.
- The atomic radii will be decreases from right handed side in the period once size of the group is downward and get increased are Cl < P < Mg < Ca.
