Study Notes
Atomic Number and Mass Number
- The atomic number indicates the number of protons in an atom.
- The mass number is the total count of protons and neutrons in the nucleus.
Periodic Table Structure
- A period on the periodic table corresponds to the number of electron shells an element has.
- A group indicates the number of electrons in the outermost shell, which influences chemical properties.
Protons and Electrons
- The atomic number is essential for determining the number of protons and, in a neutral atom, the number of electrons.
- Protons carry a positive charge, while electrons carry a negative charge.
Atomic Composition
- Protons are located in the nucleus of an atom.
- Electrons are found in shells surrounding the nucleus.
- Neutrons, which are neutral in charge, are also located in the nucleus.
