Answer:
10 neutron
Explanation:
No.of neutron=Mass no. -- atm no.(or no.of p)
No of neutron=19 -- 9
=10
The number of neutrons in a stable fluorine atom has been 10 in number.
In a stable atom, there has been a nucleus consisting of neutrons and protons. The electrons are revolving around the nucleus in their orbits.
The number of protons and electrons in an atom is equal. However, the number of neutrons in an atom is indifferent to protons and electrons.
The mass number of atoms has been the sum of protons and neutrons.
The stable fluorine atom has a mass number = 19
Number of protons = number of electrons = 9
Mass number = number of protons + number of neutrons
19 = 9 + number of neutrons
Number of neutrons = 19 - 9
Number of neutrons = 10
The number of neutrons in a stable fluorine atom has been 10 in number.
