Study Notes
Electron
- Subatomic particle with a negative charge
- Fundamental component of atoms
First Shell
- Closest shell to the nucleus of an atom
- Can hold a maximum of 2 electrons
Second Shell
- The second energy level surrounding the nucleus
- Holds up to 8 electrons
Third Shell
- The final shell present in a phosphorus atom
- Contains valence electrons which are crucial for chemical bonding
There are 15 Protons in the Nucleus
- Protons are positively charged particles located in the nucleus
- The number of protons determines the atomic number and identity of the element (Phosphorus has atomic number 15)
There are 16 Neutrons in the Nucleus
- Neutrons are neutral particles in the nucleus that contribute to atomic mass
- The number of neutrons plus protons equals the atomic mass (Phosphorus atomic mass ≈ 31)
Electron Arrangement in Bohr Model
- Electrons are arranged in shells like a clock:
- First shell: 12:00 and 6:00
- Second shell: 3:00, 9:00, and repeat
- Each shell has a specific limit on the number of electrons it can hold: 2 in the first, 8 in the second, and 8 in the third, following a pattern.
