All organic compounds have at least 1 carbon and 2 hydrogen atoms.
<span>Ionization energy (IE) is the amount of energy required to remove an electron.
If you observe the IEs sequentially, there is a large gap between the 2nd and 3rd. This suggests it is difficult to remove more than 2 two electrons. Elements that lose two electrons to become more stable are found in the Group 2A (2 representing the number of electrons in the outermost valence shell).</span>
Gallium ( Ga ) is the answer
Answer:
wavelength = 6×10⁻⁷m
f = 0.5 ×10¹⁵ Hz
Explanation:
Given data:
Energy of photon = 3.2×10⁻¹⁹ J
Wavelength of photon = ?
Frequency of photon = ?
Solution:
E = h.f
f = frequency
h = planck's constant
E = energy
f = E/h
f = 3.2×10⁻¹⁹ Kg.m².s⁻²/ 6.63×10⁻³⁴ m².Kg/s
f = 0.5 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.5 ×10¹⁵ Hz
Wavelength:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3×10⁸ m.s⁻¹ /0.5 ×10¹⁵s⁻¹
wavelength = 6×10⁻⁷m
Answer:
its electron
