1. Question 1Compare two elements and explainWarm-up

   Which element has the higher electronegativity, $\ce{Sr}$ or $\ce{Te}$, and why?

   ATe: it has more occupied electron shells.BTe: it has a larger effective nuclear charge on valence electrons in the same shell (n = 5), so it attracts bonding electrons more strongly.CSr: electronegativity decreases from left to right across a period.DSr: it has fewer valence electrons, so it attracts extra electrons more strongly.
