Chemistry Chapter 7<\/strong>, has a long and illustrious history that stretches back to the early nineteenth century. P block elements are those from Groups 13, 14, 15, 16, 17, and 18. The general outer electrical configuration ns2np1-6 is used to represent them. Metals, non-metals, and metalloids are all possible physical states for P block elements.

What is the trend in the atomic radii of the p-block elements?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The atomic radii of the p-block elements decrease from left to right in a period.<\/p>\n<p><strong>Solution:<\/strong> The atomic radii of the p-block elements decrease from left to right in a period because the number of protons in the nucleus increases, which leads to a greater attraction between the protons and the electrons, causing the electrons to be pulled closer to the nucleus.<\/p>\n<p><strong>Ques: What is the trend in the ionization enthalpy of the p-block elements?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The ionization enthalpy of the p-block elements increases from left to right in a period.<\/p>\n<p><strong>Solution:<\/strong> The ionization enthalpy of the p-block elements increases from left to right in a period because the number of protons in the nucleus increases, which leads to a greater attraction between the protons and the electrons, making it more difficult to remove an electron.<\/p>\n<p><strong>Ques: What is the trend in the electronegativity of the p-block elements?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The electronegativity of the p-block elements increases from left to right in a period.<\/p>\n<p><strong>Solution:<\/strong> The electronegativity of the p-block elements increases from left to right in a period because the number of protons in the nucleus increases, which leads to a greater attraction between the protons and the electrons, making the atom more likely to attract electrons.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Group-wise_Study_of_p-Block_Elements-2\"><\/span>Group-wise Study of p-Block Elements<span
