The answer is metallic bonding as this bond is the one
responsible of having to provide attraction in the electrons and atoms that
could lead of having substance to be made as a glue in order to provide
definite structure and it explains the description above.
<span>From the given balanced chemical reaction, it can be seen that each aluminum atom gains loses 3 electrons. Also, each copper atoms gains 2 electrons. The choice that would best give us the described scenario above is choice number 2. That is Each Al loses 3e- and each Cu gains 2e-. </span>
Answer:
The wavelength of wave is 0.33 ×10²⁰ m.
Explanation:
Given data:
Frequency of wave = 9.12×10⁻¹² Hz
Wavelength of wave = ?
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
λ = 3×10⁸ m/s / 9.12×10⁻¹² Hz
Hz = s⁻¹
λ = 0.33 ×10²⁰ m
The wavelength of radiation is 0.33 ×10²⁰ m .
