Very correct ✅
An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge). This means that it will have the same amount of negative and positive charge, giving it a net zero charge. On the other hand, an ion has different amount of electrons and protons.
B. the total charge on the electrons is equal to the total charge on the protons
Inside every atom there are:
Protons → positive (+) charge
Electrons → negative (−) charge
Neutrons → no charge
An atom has equal number of protons and electrons.
So the charges cancel each other:
+ + + and - - -
Positive + Negative = 0 (neutral atom)
The correct answer is **B. the total charge on the electrons is equal to the total charge on the protons**.
In an atom, the number of protons (which are positively charged) is equal to the number of electrons (which are negatively charged). This means that the total positive charge from the protons is exactly balanced by the total negative charge from the electrons, resulting in a net charge of zero. The other options do not accurately describe why the net charge on an atom is zero. For example, neutrons do not form a shield around the protons (option C), and the number of electrons is not half the number of protons (option D). Also, not all charged particles are in the nucleus (option A); the electrons are located outside the nucleus. Therefore, the only correct statement is option B.
This is not true!
The net charge is zero because the total charge on the electron is equal to the total charge on the proton.
Hence, the option is not there.
THE NET CHARGE IS ZERO BECAUSE THE TOTAL CHARGE ON THE ELECTRON IS EQUAL TO THE TOTAL CHARGE ON THE PROTON.... EAZIPEAZI
Chai! Myschool. I'm speechless. This is not a hard question na. In fact I won't contribute any answers to it.
