Periodic Table Flashcards
as you go down group one, what happens to the number of electrons
they increase
how many electrons are on the outer electron shell for the alkaline metals
1
what is the atomic radius
the distance from the electrons to the nucleus
remember this and mark it as red:)
bigger the atomic radius = weaker the attraction
are metal oxides acidic?
no they are alkaline
what is the product of this reaction
metal oxide + water →
metal hydroxide
what gas is produced when you react an acid with a metal alkali
hydrogen
what happens to the reactivity of group one metals as the number of protons increase
the reactivity increases
zinc is more reactive than copper
what is the product of this reaction/ is there a reaction?
copper sulphate + zinc →
zinc sulphate + copper
copper is more reactive than gold
what is the product of this reaction/ is there a reaction?
copper sulphate + gold→
no reaction
with the halogens as the number of electrons increase what happens to the reactivity
it decreases
