Aluminum is very rare in its free form. Aluminum contribute greatly to the properties of soil, where it is present mainly as insoluble aluminum hydroxide. Aluminum is a reactive metal and it is hard to extract it from its ore, aluminum oxide (Al2O3).

Answer:
Frequency = 6.67x10¹⁹ s⁻¹
Wavelength = 4.46x10⁻⁷m
e = 2.27x10⁻¹⁹J
Explanation:
To convert frequency to wavelength and vice versa we use the equation:
Wavelength = Speed of light / Frequency
<em>Speed ligth is 3x10⁸m/s</em>
<em />
For a wavelength of 4.50x10⁻¹²m:
4.50x10⁻¹²m = 3x10⁸m/s / Frequency
Frequency = 3x10⁸m/s / 4.5x10⁻¹²m
<h3>Frequency = 6.67x10¹⁹ s⁻¹</h3><h3 />
For a frequency of 6.73x10¹⁴s⁻¹:
Wavelength = 3x10⁸m/s / 6.73x10¹⁴s⁻¹
<h3>Wavelength = 4.46x10⁻⁷m</h3>
<em />
And energy, e, from frequency, is obtained as follows:
e = h ₓ frequency
<em>Where h is Planck's constant, </em>6.626x10⁻³⁴J*s
e = 6.626x10⁻³⁴J*s*3.43x10¹⁴s⁻¹
<h3>e = 2.27x10⁻¹⁹J</h3>
Answer: i think maybe 10.
