Answer:
The source of the hydrogen is coming towards us.
Explanation:
The wavelength of the hydrogen is decreasing as it goes from 486.1 nm to 486.0 nm.
<u>The wavelength of a wave is directly proportional to the distance between the observer and the object.</u>
For example, when the observer is far from the source, the observer will observe a longer wavelength which corresponds to red color if it is in the visible region.
<u>As the wavelength is decreasing that means that the hydrogen particle ( source may be a star) is coming towards the observer.</u>
Thus, we can conclude that the source of the hydrogen is coming towards us.

Ive seen that pfp on google BUT its aight ig
Explanation:
Sr has an atomic number of 38 so we'll start there.
The closest noble gas is Kr with an atomic number of 36 so it'll look like this:
[Kr]5s^2.
