Transcript text: b. ${ }_{23}^{50} V$ - of protons $=$ $\qquad$ - of neutrons = $\qquad$ - mass $\#=$ $\qquad$

Solution

Solution Steps

Step 1: Determine the Number of Protons

The notation ${ }_{23}^{50} V$ represents an isotope of vanadium. The subscript (23) indicates the atomic number, which is the number of protons in the nucleus of the atom.

Step 2: Determine the Number of Neutrons

The superscript (50) is the mass number, which is the total number of protons and neutrons in the nucleus. To find the number of neutrons, subtract the number of protons from the mass number: \[ \text{Number of neutrons} = 50 - 23 = 27 \]

Step 3: Confirm the Mass Number

The mass number is already given as 50, which is the sum of protons and neutrons.
