Hello.
Energy is absorbed by the atom.
Emission lines occur only in the case of transitions from higher to lower energy levels in which energy is emitted.
Have a nice day

Answer:
450 Å
Explanation:
The amino acids in an α-helix are arranged in a right-handed helical structure where each amino acid residue corresponds to a 100° turn in the helix, and a translation of 1.5 Å (0.15 nm) along the helical axis
Mass of protein= 33.0 kDa
33.0 kDa ×(1000Da/kDa) × ( 1 residue/ 110 Da)
=33.0 ×1000 × 0.0091
= 300 residues
300 residues × (1.5Å /residue)
=450 Å
An alpha particle is a helium nucleus without the electrons - 2 neutrons and 2 protons.
So, all you would have to do is 2 x 55, which equals 110.
