Question

Fill out the table to identify the number and name of each group and some basic properties shared by the elements in that group.

Answer 1

Answer:

1st column group 1 - group2

second column Halogen group - zero group ( inert gases )

third column - very active metals , tend to lose one electron -less reactive than group one , tend to  lose 2 electrons - very active nonmetals, tend to gain one electron - Nobel gases , do not gain or lose electrons

Explanation:

Answer 2

Group numbers :
1st - Group1
2nd - Group2
3rd - Group17
4th - Group18

Group names:
1st - Alkali metals
2nd - Alkali earth metals
3rd - Halogen
4th - Noble gas

Properties of element in group:
1st - Low melting point, low density, most reactive metal group
2nd - Second most reactive group
3rd - Most reactive group in nonmetal
4th - None reactive group, stable electronic structure

Hope this helps
