The current periodic table has the elements in order of
atomic number which is also known as the proton number
1 of 9
Group 1 metals have
1 electron in the outer shell
2 of 9
The trend in reactivity is
the further down the group, the more reactive the metal
3 of 9
Group 1 metals are known as the
alkali metals
4 of 9
Physical properties of Group 1 metals are
1. very reactive- forms an alkali hydroxide + hydrogen 2.they are soft, can be cut with a knife 3.stored under oil due to reactivity with O2 in air 4. low BP and MPs, 5. low density
5 of 9
The trend in melting groups:
the further down the group, the lower the melting point
