The lifetime of atoms in the excited state is normally
10 secs
10¹² secs

10¹ min
When the electrons in the atoms are in the state other than the ground state then this is called the atom in an excited state.
The lifetime of atoms in an excited state is the time duration in which the electrons remain in their excited state.
The lifetime of atoms in an excited state is an average lifetime derived from the decay probability.
Excited-state lifetimes are typically in few nanoseconds, The closest answer is 10?¹?
seconds. So option 1 is correct.
