If you need to produce X-ray radiation with a wavelength of 1 Å. a. Through what voltage difference must the electron be acceler
earnstyle [38]

Answer:

12.4×10^3 V

Explanation:

From E=hc/wavelength= eV

The voltage becomes

V= hc/e* wavelength

V= 6.63*10^-34*3*10^8/1.6*10^-19*1*10^-10

Note that the energy of the photon is transferred to the electron. That is the basic assumption we have applied in solving this problem. The kinetic energy of the electron is equal to the product of the electron charge and the acceleration potential.

Chlorine (cl) has an atomic number of 17. it often forms an ion by gaining 1 electron. what would its charge be?
Aliun [14]

Answer:

= -1

Explanation:

  • Chlorine belongs to the halogen group in the periodic table. It has an atomic number of 17, which indicates the number of protons and electrons in a neutral atom of chlorine is 17.
  • Therefore; with an atomic number of 17, its electronic configuration will be 2:8:7.
  • Thus; to attain a stable configuration chlorine requires to gain one electron, by so doing it becomes a negatively charged ion with a charge of -1.
