Question

Of the following, which element has the highest first ionization energy? Sr Rb Na Cl At Which isoelectronic series is correctly arranged in order of decreasing ionic radius? K^+ >Ca^2+ >S^2 rightarrow Cl^- S^2 rightarrow Cl^ rightarrow K^+>Ca^2+ Ca^2+>S^2 rightarrow K^+>Cl^- S^2 rightarrow Cl^ rightarrow Ca^2+>K^+ Ca^2+>K^+>Cl^ rightarrow S^2- The electron geometry and molecular geometry of iodine trichloride are _______and _________, respectively. trigonal bipyramidal, trigonal planar tetrahedral, trigonal pyramidal trigonal bipyramidal, T-shaped octahedral, trigonal planar T-shaped, trigonal planar

Explanation / Answer

13)

first ionization energy is the energy required to remove the mostly loosely held electron

it will be higher for the smaller atom and will increase from left to right in periodic table and decrease from top to bottom in periodic table so Helium will have th most high first ionization energy

Here Cl has the highest first ionization energy Answer

14) (E) ca2+ > K+ > Cl- > S2-   Answer

15) Trigonal bipyramidal, T shaped Answer

Electron Geometry of Iodine Trichloride Trigonal bipyramidal and

Molecular geometry of Iodine Trichloride T shaped
