A student traces the path of a ray of light via a glass prism for various angles of incidence. He analyses each diagram and attracts the following conclusion:
Variation inside of a team. The ionization enthalpies continue reducing routinely as we move down a gaggle from a single component to the other.
Answer: Electronegativity: Electronegativity will be the inclination of the atom to appeal to shared set of electrons. It is the residence of bonded atom.
Response: The weather of Group I have just one electron in their respective valence shells and thus have a strong tendency to lose this electron. The tendency to shed electrons subsequently, relies upon on the ionization enthalpy. Considering that the ionization enthalpy decreases down the team therefore, the reactivity of team 1 components improves in the identical order Li < Na < K < Rb < Cs.
