Respuesta :

atomic number =number of protons =number Of electrons =8
mass number
=number of protons +neutrons=8+9=17

The atomic number is "8" and mass number is "17".

Given:

Number of protons,

  • 8

Number of neutron,

  • 9

Number of electrons,

  • 8

The atomic number will be:

= [tex]Number \ of \ protons[/tex]

= [tex]8[/tex]

The mass number will be:

= [tex]Number \ of \ protons +Number \ of \ neutrons[/tex]

= [tex]8+9[/tex]
