An atomic emission spectrum of hydrogen shows three wavelengths: 121.5 nm,102.6 nm, and 97.23 nm

Assign these wavelengths to transitions in the hydrogen atom.

Drag the appropriate items to their respective bins.

We have that wavelengths to transitions in the hydrogen atom.

From the question we are told that

121.5 nm,102.6 nm, and 97.23 nm

Generally the equation for wavelength  is mathematically given as

Therefore

For nf=2,ni=1

For ni=1,nf=3

For ni=1,nf=4

Therefore

The Correct slots are

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
