Question
The energy of electron in first energy level is - 21.79 × 10-12 erg per atom. The energy of electron in second energy level is :
Options
A.- 54.47 × 10-12 erg atom-1
B.- 5.447 × 10-12 erg atom-1
C.- 0.5447 × 10-12 erg atom-1
D.- 0.05447 × 10-12 erg atom-1
Solution
For a particular element,
En =
erg atm-1
∴ En ∝
∴
or E2 =
- 5.447 × 10-12 erg atm-1
En =
erg atm-1∴ En ∝
∴
or E2 =
- 5.447 × 10-12 erg atm-1
