React with water
Chemical properties of non-metals? (6)
Tend to gain electrons
High ionization energy
High electronegativity
Often good oxidising agents
Form acidic oxides in presence of oxygen
Do not react water
What w metaloids share chemical properties with?
Non-metals
What is one physical property alkali metals & alkaline earth metals don’t share with metals in general?
Density, they have low density
Which is the least electronegative group? & what direction does it increase?
1, alkali metals, increases going up the group
Are alkali metals very or not very reactive?
Very reactive
What do alkali metals & alkaline earth metals form when reacting with water?
Metal hydroxide & hydrogen gas
What do alkali metals & alkaline earth metals form when reacting with oxygen?
Basic metal oxides
What is the main difference between alkaline earth metals & alkaline metals?
alkaline earth metals form a 2+ cations where alkine metals form a 1+
Is zinc a transition metal?
Not really, don’t treat it as one
Properties of transition metals
Chemical/physical properties of metals
Form colored compounds
Only some react w/ water
Only some react w/ oxygen
Have an incomplete d subshell
Often act as catalysts
Have multiple possible ionic change
Rule about naming compounds with transition metals
Always include number of the charge in roman numerals
What does halogens have the chemical & physical properties of?
Non-metals
