An atom is made of 16 protons, 17 neutrons, and 18 electrons. What is the mass number of
this atom?

Respuesta :

Answer:

The answer is 33 .

Explanation:

The mass number of an atom is the atomic mass which consists of proton and neutron. This atom has 16 protons and 17 neutrons so it has a mass of 33 :

proton number + neutron number = nucleon number / atomic mass

16 + 17 = 33

The mass number of the atom is "33".

According to the question.

Number of protons,

  • 16

Number of neutrons,

  • 17

Number of electrons.

  • 18

As we know the formula,

→ [tex]Mass \ number = Number \ of \ protons + Number \ of \ neutrons[/tex]

By substituting the values, we get

→                         [tex]= 16+17[/tex]

→                         [tex]= 33[/tex]

Thus the above response is correct.
