1.Why is the type of oil does the group 1 has to be stored into?
2.Why are all metal compounds have individual flame colour?
3.Why are all group 1 oxide compound colour is white?]]> 2021-11-15 02:15:31 UTC https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1890046976 amnihamizah https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1891197664 dr i know its out of topic but since we learn about group in more details can i use periodic table with chemical group block instead of atomic mass? ]]> 2021-11-15 13:13:51 UTC https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1891197664 https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1891258969 Hi Dr, I have some questions about alkali metals :

1. Since K,Rb ,Cs can form monoxide,peroxide,superoxide, if one of them react with oxygen , how do I know what product(monoxide/peroxide/superoxide )will be formed? 

2. Can monoxide,peroxide,superoxide be formed at the temperature of higher than the temperature written in the slides given? Is the temperature fixed for the reaction with oxygen?]]> 2021-11-15 13:37:21 UTC https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1891258969 nurafiqah1705 https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1891489043 Hi Dr. Sheela 
I have some questions regarding the tutorial 2
what is photosensitive for the alkali metal?
how the charge or size ratio of lithium differs from the rest of the elements in the group?
what is the similar properties for lithium and magnesium eventhough they from different group?
Thank you dr

I have a question about Lithium. Dr mentioned before in part 2, lithium cannot form peroxide and superoxide because it have smallest size and only can bond with one oxide, is it because of the attraction between nucleus and electrons or because there is not easy for enough peroxide or superoxide ions to cluster around the lithium?
Next,the information about Solvay Process in the notes and the one I search from internet is slightly different.Which one should i follow? (mostly different in the reaction)]]> 2021-11-16 07:56:42 UTC https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1893492714 https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1896583734 Hai Dr,i have question to ask:
1)What the meaning of photosensitive metal ?
2)how to differentiatie the product/salt that we get after experiment either lithium carbonate,sodium carbonate or other than that? ]]> 2021-11-17 11:08:37 UTC https://padlet.com/sheelachandren/SSCC1703_202120221_01_GroupIA/wish/1896583734
