Collect information regarding metallic character of elements of IA group and propare report to support the idea of metallic character increases in a group as we move from top to bottom .

Text Solution

Verified by Experts

Gorup IA elements are Li , Na ,K ,Rb , Cs and Fr .
1 ) Metallic character is the name given to the set of chemical properties associated with elements that are metals .
2 ) Chemical characteristics of metals include the following :
Form cations in ionic compounds with non-metals
Have ionic halides .
have ionic hydrides containing the ` H^(+)` ion .
Have basic oxides .
3 ) The elements with less electronegative character are metals .
4 ) All IA group elements have less electronegatively characters because they are ready to lose one electron to get octet configuration .
5 ) If we observe this group.
Reaction with non - metals :
` 2Na + O_(2) to Na _(2) O_(2) ` in this cation is `Na^(+)`
Hydrides :
`2M +H_(2) to 2MH `
`(300 - 600 ^(@)C)`
M stands for alkali metal order of ionic nature of Halides is
`LiH lt NaH lt KH lt RbH lt CsH `
Haildes : ` 2M+ X_(2) to 2 MX `
where M stands for alkali metal and X stands for halogen
All the metal halides are ionic .
Oxides : `2M +O_(2) to M_(2) O_(2) ` except Li )
`4Li +O_(2) to 2Li _(2 ) O`
All metals form peroxides .
6 ) form the above reactions we conclude that Group IA elements are metals and their metallic character increases as We go down in the group .
