이 집합의 용어 (13)

  • Monoatomic Element
    Stable as single atoms in nature, commonly found alone without bonding to identical atoms.
  • Diatomic Element
    Stable as pairs of identical atoms, naturally occurring as molecules with two atoms bonded together.
  • Polyatomic Element
    Stable as groups of more than two identical atoms, forming molecules with three or more atoms.
  • Periodic Table
    Organizes elements by atomic number and groups those with similar chemical properties in columns.
  • Chemical Property
    Characteristic that determines how an element behaves or reacts with other substances.
  • Group
    Vertical column in the periodic table where elements share similar chemical behaviors.
  • Hydrogen
    Exists naturally as a diatomic molecule, forming H2 for stability in its elemental state.
  • Phosphorus
    Naturally forms a polyatomic molecule with four atoms, represented as P4 in its stable state.
  • Sulfur
    Stable as a polyatomic molecule with eight atoms, commonly found as S8 in nature.
  • Selenium
    Found in nature as a polyatomic molecule with eight atoms, SE8, similar to sulfur due to group similarity.
  • Mnemonic
    Memory aid such as 'Have No Fear Of Ice Cold Beer' to recall the diatomic elements.
  • Molecule
    Combination of two or more atoms bonded together, as seen in diatomic and polyatomic forms.
  • Stability
    Tendency of an element to exist in a particular atomic or molecular form under natural conditions.
