Practice entering numbers that include a power of 10 by entering the diameter of a hydrogen atom in its ground state, dh=1.06×10−10m, into the answer box.
express the diameter of a ground-state hydrogen atom in meters using a power of 10. do not enter the units; they are provided to the right of the answer box.
dh=

Explanation:

According to Bohr's model, angular momentum is given by :

Since, L = m v r

So,

...................(1)

The electrostatic force is balanced by the electrostatic force as :

From equation (1),

Where

r is the radius of ground state hydrogen atom

n is the orbit

h is Planck's constant

m is the mass of electron

k is the electrostatic constant

Diameter of hydrogen atom,

So, the diameter of a ground-state hydrogen atom is . Hence, this is the required solution.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
