Question

what will be velocity of an electron revolving in second orbit of H atom​

Answer 1

hope it helps you......

Answer 2

The velocity of electron in second shell of hydrogen atom is, v=$1.094$×$10^{6} m/s$.

What is velocity of electron?

• The electron velocity in a semiconductor under the effect of an applied external electric field is probably the most representative parameter for the design of high-speed advanced electronic circuits.

What is hydrogen atom?

• An atom of the chemical element hydrogen is known as a hydrogen atom.

• The Coulomb force binds a single positively charged proton and a single negatively charged electron to the nucleus of an electrically neutral atom.

• Atomic hydrogen accounts for roughly 75% of the universe's baryonic mass.

• Isolated hydrogen atoms (also known as "atomic hydrogen") are extremely rare in normal life on Earth.

• Instead, a hydrogen atom tends to generate conventional (diatomic) hydrogen gas, H2, by combining with other atoms in compounds or with another hydrogen atom.

• In everyday English, the terms "atomic hydrogen" and "hydrogen atom" have overlapping but separate meanings.

• A water molecule, for example, contains two hydrogen atoms but no atomic hydrogen (which would refer to isolated hydrogen atoms).

According to Bohr, velocity (v) of an electron is given by relation:

$v=2.188$×$10^{6}$×$\frac{Z}{n} m/s$

Here, n=2, and Z( for H)=1.

$v=\frac{2.188*10^{6}*1 }{2}$

v=$1.094$×$10^{6} m/s$

Hence, The velocity of electron in second shell of hydrogen atom is, v=$1.094$×$10^{6} m/s$.
