QUESTION 4 1 points Save Answer Which of the following is FALSE? a. The atomic radius of Chlorine is smaller than that of Phosphorus b. The ionization energy of Bromine is larger than that of Potassium OC. The electron affinity of lodine is smaller than that of Chlorine d. The ionization energy of Aluminum is larger than that of Nitrogen e. The electron affinity of Krypton is smaller than that of Bromine QUESTION 5 1 points Save Answer The emission spectrum on the picture shows all the lines of a one-electron species resulting from transitions to the first excited state from higher energy states. Line A has a wavelength of 434 nm. Identify the one-electron species by the atomic number B A Increasing wavelength, a, Z = 1 Ob.Z-2 Oc.Z-3 Od, Z = 4

Explanation / Answer

4) The ionisation energy of aluminium is larger than that of nitrogen.As iojnisation energy is the amount of eergy require to remove an electron from an atom.As we move down the group its value decreases as number of shell increases but as we move across the periods its value increases because positive charge also increases.

5) Z=1. Number of electron is equal to the atomic number of the atom.
