- Q1Elements in what group would have the electron configuration ending in p5 ?Group 18Group 15Group 18Group 1730s
- Q2Elements in Group 1 have ____ valence electron(s) and will _______________ electron(s) to become stable.7; gain 17; gain 17; gain 11; lose 130s
- Q3Compare the atomic radii of O, F, S, Cl. Which atom is the largest and why?S because it has valence electrons in the third energy level and has less protons than Cl.Cl because it has valence electrons in the third energy level and has more protons than S.F because it has valence electrons in the second energy level and has more protons than O.Cl because it has the most number of protons and electrons.30s
- Q4Order the following elements from least to greatest ionization energy Iron Hydrogen Iodine FlorineF<I<Fe<HH<Ir< I < FH<Fe<I<FH< Fe<F<I30s
- Q5The electronegativity for Br will be _________ F because _____________.Less than; More energy levels = less attraction from nucleusMore than; Because Bromine has a higher avg. atomic massMore than; Because it has more protons so therefore more attractionLess than; Because Bromine has less valence electrons than Fluorine30s
