Interpretation:
The missing number of sub-atomic particles occurring in isotopes of silicon.
Concept Introduction:
Mass number: The number of protons and neutrons present inside the nucleus of atom are known as mass number.
Number of protons: The atomic number of an atom denotes the number of protons.
Number of neutrons: We get number of neutrons from mass number after subtracting number of protons from mass number because mass number is sum of number of protons and neutrons.
Number of electrons: In a neutral atom (non-ionic) the number of electrons is equal to the number of protons.
Given:
The table for three of the naturally occurring isotopes of silicon.
