Question

Calculate the ionisation energy of hydrogen atom using bohr model

Answer 1

Abstract Classical trajectory calculations have been used to predict the charge-transfer and impact-ionization cross sections for collisions of A+ q+ H in the velocity range of (2-7)× 10 8 cm/sec. The calculations employ a three-dimensional Monte Carlo approach that uses a classical description of the H atom and the Coulomb forces among all particles to obtain the cross sections. The positive ions studied include fully stripped A+ q, with q= 1− 8, 1 0, 1 4, 1 8, 2 6, and 36, and partially stripped B+ q, C+ q, N+ q, and O+ q, with q≥ 3. The total …

Answer 2

To find the normally quoted ionization energy, this value is multiplied by the number of atoms in a mole of hydrogen atoms (the Avogadro constant) and then dividing by 1000 to convert joules to kilojoules. This compares well with the normally quoted value for hydrogen's ionization energy of 1312 kJ mol-1.
