Chemistry
1 answer:
Paladinen [302]4 years ago
3 0

In a given neutral atom, actually the number of protons and electrons are equal. So ideally in this case the number of electrons should also be 16. However we have an ionic charge of negative 2. Since it is negative, this means there are 2 more electrons than protons, hence the answer is:

 

<span>18 electrons</span>

What is the momentum of a photon that has a wavelength of 3.00 102 nm? remember the wavelength of a photon is equal to planck's
marta [7]
De Broglie's equation is used to show that photons have both particle and wave nature. photons are quantized packets of energy. the wave nature of photons can be proven as they have a wavelength. the particle nature is given by them having both velocity and mass. 
de Broglies equation is;
λ = h / p 
where λ - wavelength 
h - Planck's constant 
p - momentum 
substituting the values in the equation 
p = h/λ
p = \frac{6.626 * 10^{-34}m^{2} kg/s }{3.00 *  10^{-7}  m}
p  = 2.20 x 10⁻²⁷ kgm/s
momentum of photon is 2.20 x 10⁻²⁷ kgm/s
