Question

The isotope 106 46Pd (106 on top and 46 on bottom)

has

1. 60 protons.

2. 106 neutrons.

3. 46 neutrons.

4. 60 neutrons.


Can I also have an explanation as well plz

Answer 1

4. 60 neutrons.

Step-by-step explanation:

The given isotopes;

¹⁰⁶₄₆Pd

In this isotope, we can deduce that the mass number is the superscript and the atomic number is the subscript;

Mass number = 106

Atomic number = 46

Mass number is the number of protons and neutrons in an atom;

Mass number = Protons + neutrons

Atomic number is the number of protons

So, Number of protons = 46

Number of neutrons = Mass number - Atomic number

= 106 - 46

= 60

Number of neutrons = 60
