1. Symbol: Each element has a unique chemical symbol (e.g., H for hydrogen, O for oxygen).
2. Atomic Number: This is the number of protons in the nucleus. It defines the element.
3. Atomic Mass: The average mass of an atom of the element (in atomic mass units, u), considering isotopes. Rounded to two decimal places for simplicity.
4. Number of Protons: Equal to the atomic number.
5. Number of Electrons: In a neutral atom, this equals the number of protons.
6. Number of Neutrons: Calculated as:
> Neutrons = Round(Atomic Mass) – Atomic Number
Example: For Oxygen:
- Atomic Mass ≈ 16.00 → rounded to 16
- Atomic Number = 8
- Neutrons = 16 – 8 = 8
---
- Hydrogen is special: It usually has no neutrons (most common isotope is protium).
- Uranium has many isotopes; the most stable and common is uranium-238, which has 146 neutrons.
- Atomic mass values are weighted averages of isotopes and may vary slightly depending on source.
