the amount of neutrons are found in one atom of 20f would definitely have to be 20f has around 11 neutrons .

One atom of 20 F contains 11 neutrons

Further Explanation

An atom

  • An atom is the smallest particle of an element that can take part in a chemical reaction. An atom is made up of sub-atomic particles; neutrons, protons and electrons.

Protons

  • Protons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.
  • The number of protons differ from one element to another and thus used as the atomic number of an individual element.
  • The nucleus of an atom is positively charged due to the positive charge of the protons.  
  • Additionally, protons do not take part in chemical reactions but in nuclear reactions.

Neutrons  

  • They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.
  • Neutrons are slightly heavier than protons.
  • The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.

Electrons  

  • They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.
  • The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.
  • Electrons are the only sub-atomic particles that take part in chemical reactions.

Atomic number

  • Atomic number refers to the number of protons in the nucleus of an atom. The atomic number of fluorine is 9, since it has 9 protons in its nucleus.

Mass number

  • Mass number refers to the sum of protons and neutrons in the nucleus of an atom.
  • Mass number = protons + neutrons

Therefore; 20 F has a mass number of fluorine.

Neutrons = Mass number - protons

                 = 20 - 9

                 = 11

Therefore; 20 F has 11 neutrons
