The element with the highest electronegativity value after fluorine $(F)$ is:

Which of the following is the correct increasing order of electronegativity for the given elements?

The correct expression for the "Allred and Rochow" scale is:

What is the value of electronegativity of oxygen?

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 :

If $P$,$Q$,$R$ and $S$ are elements of the $3^{rd}$ period of the $p-$block,among these one element is a metal and the rest are non-metals,and their order of electronegativity is given as: $P < Q < R < S$. The chloride compound of which element is hypovalent?
