Properties quizlet

Properties of an Alkali metals

• Very reactive with oxygen and water

• solid, liquid at just above room temperature

Properties of alkaline earth metals

• less reactive than. alkali metals

• compounds (not found in elemental form of nature)

Properties of noble gases

• chemically inert- stable

• monatomic at room temperature

• not bonded with anything else (found by itself)

• Glow when electric current is passed

Properties of Halogens

• physical properties of a nonmetal

• REACTIVE with group 1 and 2 to form halide salts

• variety of state at room temperature

• not found free in nature

Properties of Transition Metals

• physical metal properties

• vary in reactivity

• less metallic- being vividly colored

Properties of Lanthanides

• physical metal properties

• Similar reactivity to alkaline earth metals

• night vision

Properties of Actinides

• RADIOACTIVE

• decays over time

Properties of Base Metals

• common (more abundant)

• metal properties (but less)

• tend to tarnish, corrode, etc.

• lower melting/boiling point and softer than transition metals

properties of ionic compounds and how they relate to structure

• Shape- Crystal,

• Colors- from transition metals,

• Crystal lattice- very strong

  • high melting point, hard, brittle (when hit with force, ions of the same charge near each other repel and shatters)

  • Smooth planes because of regular arrangement

• conductivity- only when melted or dissolved in water (cations and anions free to move)

Structure: Crystal lattice

properties of molecular compounds and how they relate to structure

• any state

• low boiling point- malleable (molecules are more easily separated)

• does not conduct electricity (no freely moving electrons

• does not dissolve (no charge)

• easy to break between multiple molecules

Structure: Distinct

Properties of an acid in aqueous solution

• strong electrolytes- conduct electrical currents (ions)

• sour taste

• change the color of acid/base indicators

• React w/ active metals - hydrogen gas

• React w/ bases- salt components & H2O

  • When equal, will neutralized= ionic compound (salt + water)

• pH less than 7

• burn skin

• Produce hydrogen ions when dissolved in water

• Can be weak electrolyte

Properties of a base in aqueous solution

• strong electrolytes- conduct electrical currents (ions)

• bitter taste

• Feels slippery

• change the color of acid/base indicators

• Do not react w/ metals

• React w/ acids - salt + water

• pH greater than 7

• burn skin

• Produce hydroxide ions when dissolve in water

• Can be weak electrolyte

properties of a metal

Shiny, conductive, malleable, reactive with less valence electrons, high melting/boiling point, magnetic properties (MAIN TAKEAWAY: Less VE or more energy levels = metal)

properties of nonmetals

Elements that are generally poor conductors of heat and electricity. (Dull, not conductive, brittle, not reactive, low melting/boiling point)

properties of a metalloid

An element with properties between those of metals and nonmetals, also known as semimetals. Tends to be brittle and dull.
