    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).
    • 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.
