Front:
Energy definitions, conservation & key energy formulas
Back:
Wasted energy: dissipated, usually as thermal
Useful energy: energy you want
Closed system: no energy enters or leaves
Conservation of energy: energy cannot be created or destroyed
Kinetic energy: Ek = 0.5 k m v2
Elastic potential = Ek = 0.5 k e2
GPE: Ep = m g h
Work done: Force × Distance

Front:
Reactivity trends in Groups 1, 7, and 0
Back:
Group 1: Reactivity increases going down (outer electron farther, easier to lose)
Group 7: Reactivity decreases going down (harder to gain an electron)
Group 0: Unreactive because full, stable outer shells
══════════════════════════════════════
Front:
Halides, alkali metals, and displacement reactions
Back:
Halide: Metal + Halogen → Metal halide
Alkali + Water: → Alkali hydroxide + Hydrogen
Displacement: More reactive halogen replaces a less reactive one
Inert: Means unreactive and stable
══════════════════════════════════════
Front:
Newland vs. Mendeleev + Group 1/7/0 properties
Back:
Newland (1864): Ordered by mass; saw repeating patterns; forced wrong groupings
Mendeleev (1869): Left gaps; accurate predictions; broke mass order for properties
Group 1: Low density, shiny, soft metals, good conductors
Group 7: Coloured, toxic non‑metals, poor conductors
Group 0: Colourless gases, very unreactive, poor conductors

Front:
Key definitions in atomic structure
Back:
• Atom: smallest particle of matter, not visible to the naked eye
• Element: made of only one type of atom
• Compound: two or more elements chemically bonded
• Isotopes: same element, different number of neutrons
• Ions: atoms with a charge from gaining/losing electrons
══════════════════════════════════════
Front:
Subatomic particles + electron shells
Back:
Reactivity depends on electrons, not isotopes
Law of conservation of mass: atoms aren’t created or destroyed in reactions
Protons: mass 1, charge +1
Neutrons: mass 1, charge 0
Electrons: mass ~0, charge –1
Shell rule:
1st shell: 2 electrons
2nd shell: 8 electrons
3rd shell: 8 electrons

Front:
Timeline of atomic model development
Back:
Democritus (400 BCE): matter made of tiny particles
Dalton (1803): atoms are solid spheres
Thomson (1897): electrons discovered; plum pudding model
Rutherford (1911): nucleus + empty space
Bohr (1913): electrons in fixed orbits
Schrödinger (1926): electron clouds
Chadwick (1932): neutrons discovered
