Answer:
They both have 7 electrons in their outer shell
The various atomic masses of the same element are called<u> isotopes</u>. They have the same number of protons but different number of neutrons.
C = vf
c stands for the speed of waves (which is a constant that is 3 x 10^8)
v stands for the wavelength (which is given)
f stands for frequency (what we are solving for)
3 x 10^8 = (1.08 x 10^-6)f
Divide both sides by the given wavelength
f = 2.78 * 10^14 seconds
It always has birds, it's in the South.
