Assuming that the number of mols are constant for both conditions:
Now you plug in the given values. V_1 is the unknown.
Separate V_1
V= 162.782608696 L
There are 2 sig figs
V= 160 L
Answer: They both have two valence electrons.
Explanation:
Atoms with the same number of valence electrons normally have similar properties.
Answer:
n = 3
Explanation:
Given the formula for the transition energy of an atom with 1 electron:
For the H transition n=5 to n=2:
Then we solve for nf with Z=2 (Helium)
Is near 3, actually the energy of the transitions are:
H (5⇒2) = -2.85 eV = 434 nm (Dark blue)
He (4⇒3) = -2.64 eV = 469 nm (Light blue)
I thought it was cool to see the actual colors. Included them.
