Question

Which statement is correct regarding neutron- to-protonratios? (a) If the n/p ratio of an atom is greater than 1,it's nearlyalways an isotope and is always very stable (b) If the n/p ratio is greater than 1, the element isprobably a heavier element and contains more protons thanneutrons (c) If the n/p ratio is greater than 1, an element is alwaysradioactive (d) If the n/p ratio is 1, the element is likely to be alighter element Which statement is correct regarding neutron- to-protonratios? (a) If the n/p ratio of an atom is greater than 1,it's nearlyalways an isotope and is always very stable (b) If the n/p ratio is greater than 1, the element isprobably a heavier element and contains more protons thanneutrons (c) If the n/p ratio is greater than 1, an element is alwaysradioactive (d) If the n/p ratio is 1, the element is likely to be alighter element

Explanation / Answer

             The n / p ratio is used todetermine the stability of the nucleus .      The nucleides having the n/ pratio between 1 to 1.6 are the stable nucleides . The nucleideswith n /p ratio less than 1 or greater than 1.6 areunstable and disintigrate to give , , and radiations .        The n/p ratio of thelighter nuclei (A<20) is close to 1 .             hence thetrue statement is d) .
