Mass:
* Protons: Have a mass of approximately 1.6726 x 10^-27 kg. This is about 1836 times heavier than an electron.
* Electrons: Have a mass of approximately 9.1094 x 10^-31 kg.
Charge:
* Protons: Have a positive charge of +1.602 x 10^-19 Coulombs.
* Electrons: Have a negative charge of -1.602 x 10^-19 Coulombs.
Key Points:
* Opposite Charges: Electrons and protons have equal and opposite charges, which is why they attract each other.
* Atomic Structure: Protons reside in the nucleus of an atom, while electrons orbit the nucleus.
* Atomic Number: The number of protons in an atom's nucleus defines its atomic number, which determines the element.
