1.2 - PERIODIC TABLE Flashcards
PURE SUBSTANCES
PERIODIC TABLE OF ELEMENTS
Good electrical conductors ad
heat conductors
METALS
Malleable (can be sharpened)
- Ductile (can be stretched into wires)
- Possess metallic luster
- Opaque
- Solid at room temperature
METALS
POOR CONDUCTORS OF HEAT AND ELECTRICITY
- BRITTLE
- NON DUCTILE
- DO NOT POSSESS METALLIC LUSTER
- TRANSPARENT
- SOLID, LIQUID AND GAS AT ROOM TEMPERATURE
NON-METALS
NTERMEDIATE BETWEEN METAL
AND ON-METAL
- CAN BE SHINY OR DULL
- EXCELLENT SEMICONDUCTORS
METALLOIDS
WHEN ELEMENTS
CHEMICALLY COMBINE IN
A FIXED PROPORTION

GROUP 1A ARE CALLED
ALKALI METALS
most reactive especially with water
ALKALI METALS
ALKALI METALS ELEMENTS
HYDROGEN LITHIUM SODIUM POTASSIUM RUBIDIUM CESIUM FRANCIUM
inflammable air (ignites immediately); most abundant type of gas in the universe
HYDROGEN
used in batteries
LITHIUM
for persons who are clinically diagnosed with mania
Lithium Carbonate
original name was Natrium; an extracellular element; responsible for blood volume
SODIUM
-it is excreted by your body as fluids (outside the cell)
saponifying agents for hard soaps (bases and oil; palm oil)
Sodium Hydroxide (soso ang tigas!)
original name was Kalium; major intracellular ion used for soft or liquid soaps
Potassium (pota ang lambot!)
main cause for relaxation in muscles
Potassium Chloride
- used for mercy killing I.V Bolus
- suero: heart will fail due to too much relaxation
RUBIDIUM, CESIUM, FRANCIUM
for medical uses
GROUP 2A KNOWN AS
ALKALINE EARTH
GROUP 2A ELEMENTS
BERYLIUM MAGNESIUM CALCIUM STRONTIUM BARIUM RADIUM
most toxic metal
BERYLIUM
MAGNESIUM CLASSIFICATION DIFFERENCE:
MAGNESIUM HYDROXIDE
ALUMINUM HYDROXIDE
magnesium hydroxide - a laxative for pooping purposes
ALUMINUM HYDROXIDE - NO POOP
for calming and seizure medication
Magnesium Sulfate
contraction of smooth muscles
Calcium
chemotherapeutic agent
Strontium
GROUP 3A KNOWN AS THE
BORON FAMILY
GROUP 3A ELEMENTS
BORON ALUMINUM GALLIUM INDIUM THALLIUM
