Capacity of a d subshell OR Capacity of a p subshell 4. Oxidation state of chlorine in ClO^-1_3 OR oxidation state of chlorine in CIO^-1_4 5. Energy to remove one electron from a potassium atom OR Energy to remover one electron from a krypton (Kr atom 6. Electronegativity of nitrogen OR Electronegativity of arsenic 7. Electronegativity of nitrogen OR Electronegativity of carbon 8. Charge of an aluminum ion OR Charge of a sodium ion 9. Energy of a 3s orbital OR Energy of 3p orbital 10. Strength of a bond with bond order of 1 OR Strength of a bond with bond order of 1.5 11. Number of oxidation states possible for sodium OR Number of oxidation states possible for iron 12. Density of water OR Density of lead 13. Number of meters in a kilometer OR Number of particles in a mole 14. Radius of a potassium atom OR Radius of a potassium ion 15. Number of bonds in an oxygen molecule OR Number of bonds in a nitrogen moleculeExplanation / Answer
The items with larger value are
1. Energy of 500 nm photon
E = hc / w
where w is the wavelength
so energy is inversely related to energy of photon
2. Volume of 1 mole of gas at STP
1 mole of gas at STP occupies 22.4 litre of space
3. Capacity of d subshell
d subshell has 10 electrons and p subshell has 6 electrons.
4. Oxidation state of chlorine in ClO4-
In ClO3-, Oxidation state is +5 , in ClO4- , it is +7
