From laboratory measurements, we know that a particular spectral line formed by hydrogen appears at a wavelength of 486.1 nanome

ters (nm). The spectrum of a particular star shows the same hydrogen line appearing at a wavelength of 486.0 nm. What can we conclude?

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.

Highest ionization energy: Li, Be, B
Ad libitum [116K]

Hello!


On the periodic table, as we go down the periodic table, the ionization energy decreases, but as we go across the periodic table (left to right), the ionization increases.


On the periodic table, lithium (Li) is located in column one, beryllium (Be) is located in column two, and (B) boron is located in column 13. As stated above, when we go across the periodic table (left to right), the ionization increases.


Therefore, the element with the highest ionization energy is Boron, or symbol B on the period table.
