Question

. Find out the number of electrons, protons and
neutrons in the following:
Fluorine atom (F), fluoride ion (F-) and fluorine
molecule (F.. Atomic number of F = 9 and mass
number = 19.​

Answer 1

Answer:

$f = 9$

Explanation:

I hope you help

Answer 2

Answer:

Given,

Atomic number (F)=9

& Mass number=19

Explanation:

We know that,

Atomic number=Proton of That atom

so,Proton=9

Electron=9

& Neutron=(Mass no. - Atomic number)=19-9=10

This is the answer of Fluorine atom.

In Fluoride ion(F-)=Proton=9

Electron=9+1=10

& Neutron=19-9=10

This is the answer of Fluoride ion(F-)

In Fluorine molecule(F2)=Proton=9

Electron=9-2=7

& Neutron=19-9=10
