Study Notes
Atomic Structure
- The main component of an atom's nucleus is protons and neutrons.
Protons
- Protons have a positive charge.
- The number of protons in an atom is equal to the atomic number (Z).
- The number of protons in an atom determines the element of an atom.
Neutrons
- Neutrons have no charge.
- The main function of neutrons in an atom is to stabilize the nucleus.
- The number of neutrons in an atom can vary, leading to different isotopes of the same element.
Electrons
- Electrons have a negative charge.
- Electrons are located in energy levels outside the nucleus.
- The number of electrons in an atom is equal to the number of protons (atomic number) in a neutral atom.
Atomic Number and Mass Number
- The atomic number (Z) of an atom is the number of protons in the nucleus.
- The mass number (A) of an atom is the sum of protons and neutrons in the nucleus.
- The difference between the mass number (A) and the atomic number (Z) of an atom gives the number of neutrons (N=A-Z).
Symbolic Representation
- The symbol 'A' in atomic structure represents the mass number (sum of protons and neutrons).
- The symbol 'Z' in atomic structure represents the atomic number (number of protons).
- N=A-Z represents the number of neutrons in an atom.
