Question

If number of electrons in an atom is 8 and number of protons is also 8 then (neutrons=7)
1.what is the atomic number of the atom?
2.what is the charge in the atom?
3.what is the mass number of the atom?

Answer 1

Hey there !

Solution:

• Number of Protons = 8
• Number of Electrons = 8
• Number of neutrons = 7

Atomic Number = Number of electrons = Number of protons

=> Atomic Number = 8

Charge of an atom = Number of protons - Number of electrons

=> Charge of an atom = 8 - 8 = 0 ( Neutral charge )

Mass Number of an atom = Number of Protons + Number of Neutrons

=> Mass number = 8 + 7 = 15 u

Hope my answer helped !

Answer 2

Answer:

Number of protons=8.

Number of Electrons= 8

Number of protons= 7
