Periodic Table and Atomic Structure
The periodic table is organised by atomic number. Elements in groups can share chemical patterns because of related outer-electron structures.
What to remember
- Atomic number equals proton number.
- Neutral atoms have equal protons and electrons.
- Ions form by electron gain/loss.
- Elements are arranged by increasing atomic number.
- Group patterns reflect related electron structure.
Key words
atomic number — proton count
ion — charged atom/group
group — vertical periodic-table column
period — horizontal row
valence electron — outer-shell electron involved in bonding
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 25 attempts on the same browser.
