Download Solution PDFThe correct answer is 6.25 x l018 electrons.
Key Points
- One coulomb (C) of charge represents an excess or deficit of 6.25 × l018 electrons.
- The quantity of charge (Q) on an object is equal to the number of elementary charges on the object (N) multiplied by the elementary charge (e).
- Change on 1e− = 1.602 × 10−19 C
- If total charge = 1 C
- Total no. of e− =1/1.602×10−19
- 1 C = 6.24×1018 e−
Additional Information
- Proton-positive; electron-negative; neutron-no charge.
- The charge on the proton and electron are exactly the same size but opposite.
- The same number of protons and electrons exactly cancel one another in a neutral atom.
- Electrons are one of three main types of particles that make up atoms. Unlike protons and neutrons, which consist of smaller, simpler particles, electrons are fundamental particles that do not consist of smaller particles.
- They are a type of fundamental particle called leptons. All leptons have an electric charge of −1 or 0.
- Electrons are extremely small.
