Answer :
(1) The number of protons in silicon is, 14
(2) The number of neutrons in zinc is, 35
Explanation :
Atomic number is defined as the number of protons or number of electrons.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons.
Number of neutrons = Mass number - Number of protons
Prat 1 :
As we know that, silicon is a metalloid which belongs to group 14 and period 3.
The atomic number of silicon = 14
Atomic number = Number of protons = 14
Part 2 :
The given element is, zinc (Zn)
Atomic number of Zn = 30
Atomic number = Number of protons = 30
Mass number of Zn = 65
Number of neutrons = Mass number - Number of protons
Number of neutrons = 65 - 30
Number of neutrons = 35
