If an electron jumps from higher energy level to lower energy level, it releases energy which is known as emission of energy. Note that the electron can absorb or emit only that much amount energy which is equal to energy difference between two levels.

A gaseous mixture consists of 1.08 mol of helium, 0.36 mol of neon, and 1.58 mol of argon. What is the mole fraction of helium in the mixture?

Mole fraction of helium = moles of helium/ total moles= 1.08/(1.08 + 0.36 + 1.58) = 0.36

the ionization energy of hydrogen atom is 13.6 eV. The kinetic energy of the electron in hydrogen atom is a) 13.6 ev B0 31.6 eV C) 6.8 eV D0 21.7 eV

The energy of the electron in the nth Bohr orbit is En=-Z2*Rch/n2 Given, ionization energy of hydrogen atom = Rch=13.6 eV. Therefore, En=-(13.6 eV)*Z2/n2. Kinetic energy of the electron in...
