Explanation:
The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m
We need to find which wave have a higher frequency.
The relation between frequency and wavelength is given by :

Let f₁ and f₂ be the frequency of wave 1 and wave 2.

And

Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.
One atom is a metal and one is a nonmetal.
One atom has high electronegativity value, while the other value is really low
Answer:
there'd be 2 electrons
Explanation:
number of electrons= number of protons
