Answer:
b
Explanation:
orbital overlap electron densities.
Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons.
Speed of light = freq * wavelength
<span>wavelength = speed of light / freq = (3*10^8 m/sec ) / (2.6 * 10^9 /sec) = 1.15 * 10^(-1) m </span>
<span>1.15 * 10^(-1) m *(10^9 nm / m) = 1.15 * 10^8 nm</span>
The answer is a Roman numeral.
Ex:
1: I
2: II
3: III
4: IV
5: V
6: VI
7: VII
8: VIII
9: IX
10: X
