प्रश्न
An atom consists of charged particles called electrons and protons. Each proton has a charge of +1 and each electron has a charge of –1. Remember number of electrons is equal to number of protons, while answering these questions:
What will be the charge on an atom if it loses an electron?
उत्तर
If an atom loses an electron, it will have (a – 1) electrons and a protons.
∴ Charge in one electron = (–1)
∵ Charge in (a-1) electrons = (a – 1) × (–1) = – (a – 1) = (1 – a)
∴ Charge in one proton = (+1)
∵ Charge in a protons = (+1) × a = (+a)
Hence, total charge on the atom = Charge of electrons + Charge of protons
= 1 – a + a
= + 1
