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 d H = 1.06 × 10 − 10 m , into the answer box.

The diameter of the hydrogen

Explanation:

From the given information:

Using the concept of Bohr's Model, the equation for the angular momentum can be expressed as:

Where the generic expression for angular momentum is:

L = mvr.

replacing the value of L into the previous equation, we have:

----- (1)

The electron in the hydrogen atom posses an electrostatic force which gives a centripetal force.

  ----- (2)

replacing the value of v in equation (1) into (2), and taking r as the subject of the formula, we have:

For ground-state n = 1

Therefore, the diameter of hydrogen d = 2r
