Chapter 30, Problem 50A

To determine

To calculate:

Number of particles that makes up an atom of $Ag$ .

Answer to Problem 50A

There are $47$ Electrons, $47$ Protons and $62$ Neutrons.

Explanation of Solution

Given:

An atom: $Ag$

Where,

Atomic number $\left(Z\right)$ = $47$

Atomic Mass number $\left(A\right)$

  $=109$

Formula Used:

Number of protons is given by $\left(Z\right)$ .

Number of neutrons is given by $A-Z$ .

Number of electrons is given by

Where,

  $A$ : Atomic mass number of atoms.

  $Z$ : Atomic number of atoms

Calculation:

For an atom, $Ag$ ,

Substitute the values of $A$ and $Z$ to find the number of protons, neutrons and electrons.

Here,

Number of electrons $\left(Z\right)=47$

Number of protons $\left(Z\right)=47$

Number of neutrons $=A-Z=109-47=62$

Conclusion:

  $47$ Electrons, $47$ Protons and $62$ Neutrons form the atom of $Ag$ .
