Answer:
2.7 x 10^-19 J
Explanation:
The formula needed for this problem is
E = hν
where E = energy, h = Planck's constant = 6.626x10^-34 and ν is the frequency
c = λν
where c = speed of light = 3x10^8, and λ = wavelength
3x10^8 = 7.35x10^-7 . ν
ν = 4.08 x 10^14 Hz
E = 6.626x10^-34 . 4.08x10^14 = 2.7 x 10^-19 J
Because their atoms have the same number of electrons in the highest occupied energy level
<span>quartz (SiO2) is a compound. A compud is the combination of two or more elements. It is a compound because three elements are formed, the silicon and the two atoms of oxygen.</span>
Answer:
Ground state electronic configuration of nitrogen atom can be represented by 1, 4 only. All the unpaired electrons have spins aligned in the same direction only.
Explanation:
You can have as many controls as necessary, But they must remain equal at all times in order to get the most accurate results
