Questions and Answers
What happens when sodium reacts with water?
Sodium reacts with water to form sodium hydroxide and hydrogen.
How do the reactants' atoms change as you go down the periodic table?
The atoms become bigger and their attraction to electrons is weaker, making it easier to lose electrons.
What is the relationship between the size of the atom and its reactivity?
As the size of the atom increases, its reactivity decreases.

Study Notes
Election Arrangement
- There are 2 eledias in the first siell, 8 elichons in the second siell, and 3 in the third siell.
Chemical Reactions
- Sodium (Na) reacts with water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2).
- The reactivity of alkali metals increases as you go down the group in the periodic table.
- Alkali metals easily lose one electron to form a positive ion (cation).
Periodic Trends
- Atomic size increases as you go down a group in the periodic table.
- Electron attraction (electronegativity) decreases as you go down a group in the periodic table.
Unknown Concepts
- Pilazion-gora and glands are mentioned, but their context is unclear.
- Itulagens and Malagens are unknown terms, possibly related to chemical reactions or periodic trends.
