Ans: As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit will <u>increase.</u>
The energy (E) is related to the frequency (ν) by the following equation:
E = hν
where h = planck's constant
The change in energy i between levels is:
ΔΕ = h(Δν) -----(1)
Based on the above equation, as the changes in energy levels increase, the frequency of emitted radiation will also increase.
Answer: Yes
Explanation:
due to the nitrogen atom and its lone pair is in opposition to the moment associated with the three polar N-F bonds in NF3. NCl3 also has a small dipole moment
Answer: A. uranium salt
Becquerel made a conclusion that it was the uranium that causes the images found in the photographic plates. Though his theory was disproved during the first time,he continued to develop it. Then, it is through this experiment that Becquerel discovered radioactivity.
We know the sun is primarily made from hydrogen and helium on the basis of its spectrum.
<h3>What is Sun's spectrum?</h3>
Sun's spectrum refers to the light of the Sun whose wavelength spectra can be used to identify atomic composition.
Thus spectrum (Sun's spectrum) initiates with the red light (700 nm) and ends with the blue (380 nm).
In conclusion, we know the sun is primarily made from hydrogen and helium on the basis of its spectrum.
