Question
Given below are two statements :Statement I : The electronegativity of group 14 elements from Si to Pb gradually decreases.Statement II : Group 14 contains non-metallic, metallic, as well as metalloid elements.In the light of the above statements, choose the most appropriate from the options given below :Statement I is false but Statement II is trueStatement I is true but Statement II is falseBoth Statement I and Statement II are trueBoth Statement I and Statement II are false
Solution
Both Statement I and Statement II are true.
Statement I is true because electronegativity generally decreases down a group in the periodic table. This is due to the increase in atomic size, which results in the outer electrons being further away from the nucleus and thus less strongly attracted to it.
Statement II is also true. Group 14 of the periodic table, also known as the Carbon group, contains a variety of elements with different properties. Carbon (C) and Silicon (Si) are non-metals, Germanium (Ge) is a metalloid, and Tin (Sn) and Lead (Pb) are metals.
