in the Periodic Table it is the most reactive metals!
Sodium belongs to the group 1 of the periodic table, known as the alkali metals group.
Group 1 Metals
Group 17 or halogens will combine readily with group 1 elements.
Hydrogen is not in group 7. It is in group 1 of the periodic table.
The reactivity increase down in the group.
when the amount in one group is different then that of the other
Group 1
group 1
It is group 1.
Group 1 elements are more reactive than that of group 2 elements.
group 3- (n-1)d1 ns2. Group 12 (n-1)d10 ns2, groups 4-11 do not necessarily have identical outer electron configurations. Where n represents your period that you are in.
Hydrogen is found in group 1 row 1 of the periodic table
