Question

hey, what are some tricks to learn the Bohr formulas?
energy and radius, etc​

Answer 1

hlo mate here is ur ans.....

Definition and value

The CODATA value of the Bohr radius (in SI units) is 5.29177210903(80)×10−11 m. The Bohr model derives a radius for the nth excited state of a hydrogen-like atom. The Bohr radius corresponds to n = 1.

By keeping the electrons in circular, quantized orbits around the positively-charged nucleus, Bohr was able to calculate the energy of an electron in the nth energy level of hydrogen: E ( n ) = − 1 n 2 ⋅ 13.6 eV E(n)=-\dfrac{1}{n^2} \cdot 13.6\,\text{eV} E(n)=−n21⋅13.

Note that the negative sign coming from the charge on the electron has been incorporated into the direction of the force in the equation above. This gives m v2 = k e2 / r, so the kinetic energy is KE = 1/2 k e2 / r. The potential energy, on the other hand, is PE = - k e2 / r.

u dont have tricks ..

u should remember them

By keeping the electrons in circular, quantized orbits around the positively-charged nucleus, Bohr was able to calculate the energy of electron in the nth energy level of hydrogen: E (n) = - 1n 2- 13.6 eV E(n)=-\dfrac{1 n^2} \cdot 13.6\,\text{eV E(n)=-n 21-13.

Note that the negative sign coming from the charge on the electron has

been incorporated into the direction of the force in the equation above.

This gives m v2 = k e2/r, so the

kinetic energy is KE = 1/2 %D

k e2 / r. The

potential energy, on the other hand, is

PE = - k e2 / r.
