The two lines show that these are the only two lines that do not cause energy transition in the sodium atom. Option D
<h3>What are the two lines in the spectrum of sodium atom?</h3>
The spectrum of the sodium atom appears as a doublet. This implies that there are two lines in the spectrum and they appear as bright yellow lines that are not spaced apart in the spectrum.
The two bright yellow vertical lines in the spectrum shows that these are the only two lines that do not cause energy transition in the sodium atom.

Question
A female spinach plant with flat (Ff) leaves is crossed with (pollination and fertilization occur) a male spinach plant with crinkly (ff) leaves. Explain wha
Explanation:
Answer: d = 7.9 g/cm^3
Identify the given information.
m = 79 g
v = 10 cm^3
Choose which formula you should use. In this case, you are finding the density.
d = m/v
Substitute and solve.
d = 79 g/10 cm^3
d = 7.9 g/cm^3
The element X is Copper.
Explanation :
Reactive metals from 3d transition series like Cu are very reactive because their standard reduction potential values are low.
Hence, when treated with a acid it tends to liberate hydrogen gas.
Also, because of its low reduction potential value, it can easily displace lead and tin from their salt solutions.
