Order of increasing Ionization Energy is  Kr>As>Sb >Sn.

<u>Explanation:</u>

  • In the periodic table, the ionization energy increases when we move across the period also decreases when we move down the group. Tin (Sn) is in the carbon group, Arsenic and antimony is present in nitrogen group(Sb,As), and Krypton is present in Helium group(Kr). As we know, Helium or zero group elements have maximum ionization energy, since it has fulfilled orbitals, So Kr has the maximum ionization energy, where as As and Sb is present in lower periods than that of Krypton and then comes tin.
  • So ionization energy is in the increasing order of  Kr>As>Sb >Sn.
  • Hence the order follows as,Kryton>Arsenic>Antimony>Tin

A sample of a compound containing only carbon and oxygen decomposes and produces 24.50g of carbon and 32.59g of oxygen. what is
Fynjy0 [20]
<span>Carbon Monoxide. First, determine the relative number of moles of each element by looking up the atomic weights of carbon and oxygen Atomic weight carbon = 12.0107 Atomic weight oxygen = 15.999 Moles of Carbon = 24.50 g / 12.0107 g/mol = 2.039847802 mol Moles of Oxygen = 32.59 g / 15.999 g/mol = 2.037002313 mol Given that the number of moles of both carbon and oxygen are nearly identical, it wouldn't be unreasonable to think that the empirical formula for the compound is CO which also happens to be the formula for Carbon Monoxide.</span>
