write the symbol for the atom that has an
Expert Solution
Step 1
It is required to determine the symbol for the atom that has an atomic number 9 and mass number 19 and the number of neutrons does this atom have.
Step 2
Fluorine is the atom which has an atomic number 9 and mass number 19
symbol of Fluorine = F
number of protons in Fluorine = atomic number = 9
number of electrons in Fluorine = number of Protons = 9
Number of Neutrons in Fluorine:
mass number = number of neutrons + number of protons
number of neutrons = mass number - number of protons = 19 - 9 = 10
