1.	The first ionizationsenergy of Na is 495.9KJ/mole, what is thelongest wave length oflight that could removean electron from Na?(with proper steps please
Answer» ANSWER: a) $2.41{10}^{-7}$ Explanation:* IONIZATION energy of Na is 495.9KJ/MOLE 1 mole= 495.9KJ 1 atom= 495.9KJ/Na = 495.9/6.02310^23 = hC/λ* λ= $\dfrac{6.023{10}^{23}}{495.96.626{10}^{34}3{10}^{8}}$ = $2.41{10}^{-7}$

Answer»

a) $2.41*{10}^{-7}$

Explanation:

IONIZATION energy of Na is 495.9KJ/MOLE

1 mole= 495.9KJ

1 atom= 495.9KJ/Na

= 495.9/6.023*10^23 = hC/λ

λ= $\dfrac{6.023*{10}^{23}}{495.9*6.626*{10}^{34}*3*{10}^{8}}$

= $2.41*{10}^{-7}$
