Question

E/m ratio calculation for na+ ion

Answer 1

Given:

1) The given sample is sodium ion (Na⁺).

To find:

1) The e/m ratio (charge to mass ratio) of this ion.

Solution:

Given, the sample is Na⁺.

It is represented as [₁₁Na²³]⁺.

This is because the mass number is 23 and the atomic number is 11.

The charge on it (e) is = 1.

The mass number (m) is = 23.

As a result, the e/m ratio is = e/m

= $\frac{1}{23}$

The e/m ratio for Na⁺ ion is $\frac{1}{23}$
