Question:
Of the following atoms, which one has the highest n/p ratio?
Of the following atoms, which one has the highest n/p ratio?
Updated On: Aug 15, 2022
- $Ne^{16}$
- $O^{16}$
- $F^{16}$
- $N^{16}$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Highest n/p ratio
$_{10}Ne^{16} \Rightarrow^{p=10}_{n=6}\quad\quad\frac{n}{p}=\frac{6}{10}=0.6;\, _{8}O^{16}\,\Rightarrow^{p=8}_{n=8}\qquad n/p=1$
$_{9}F^{16} \Rightarrow^{p=9}_{n=7}\, \frac{n}{p}=\frac{7}{9}; \, _{7} N^{16} \Rightarrow^{p=7}_{n=9}\, n/p=\frac{9}{7} =1.2857\,_{=0.778}$

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
