Chemical Families Flashcards
Alkali metals
Low melting point and react easily with water and air, very soft
- shiny, silvery metals
- extremely reactive
- combine easily with other elements to form compounds
REACT MOST VIOLENTLY WITH WATER
Alkaline earth metals
Shiny, silvery metals, but are non-soluble
Metalloids
Element with metallic and non-metallic properties (silicon)
Halogens
Non-metals, very reactive and have a noticeable colour, growing in intensity
REACTIVITY INCREASES UP THE GROUP
VERY POISONOUS
Noble gases
Elements that glow if an electric current is passed through them, none of these gases are chemically reactive, rarely form chemical compounds with other elements
DO NOT REACT WITH ANYTHING
GROUP 8/18
Group of one
Hydrogen, colourless, odourless, tasteless, and highly flammable
Metals
Element that is malleable and ductile and conducts electricity and heat
Non-metals
Elements that are grouped together mainly because they do not resemble metals (carbon)
