Valence electrons are the electrons that are in an atom's outermost layer.
Every atom is made of protons, neutrons, and electrons.
Electrons are outside them both.
They have energy levels (number of electrons per layer)
And the number they have on the farthest layer are the valence electrons.

<u>Answer:</u> The wavelength of an electron is
<u>Explanation:</u>
To calculate the wavelength of a particle, we use the equation given by De-Broglie's wavelength, which is:
where,
= De-Broglie's wavelength = ?
h = Planck's constant =
m = mass of electron =
v = velocity of electron =
Putting values in above equation, we get:
Hence, the wavelength of an electron is
