Periodic Table Flashcards
What are the general properties of metals
Shiny
Good conductors of heat+electricity
Malleable ductile
High mekting point
Solid at room temp
What are the properties of alkali metals
Alkali solution (hydroxide)
Low melting point+density
Soft
Not use full but compounds
What does halogen mean
Salt former
What are the irons of halogens calledi
Halide ions
End in ide
Physical properties of halogens
Melting point+density increase down the group
Bad conductors
Colour gets darker
Chemical properties of halogens
Reactivity decreases down the group
More reactive halogen can replace a more reactive halide
How are noble gasses described
Monatomic gases and inert
Physical properties of noble gasses
Low boiling point
Boiling point increases down the group
Particles widely spaced-low densities
What are the uses of noble gasses
Helium balloons and argon light
What is a precipitate
a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid.
Chemical properties of transition metals
Colored compounds
Variable oxidation states
Catalysts
What are the physical properties of transition metals
Those of normal metals
What is oxidation
When an atom loses electrons to form cations
What is reduction
When an atom tains electrons and becomes an anion
