1.	Ions of an element of group 1 participate in the transmission of nerve signals and transport of sugars and amino acids into cells . This element imparts yellow colour to the flame in flame test and forms an oxide and a peroxide with oxygen . Identify the element and write chemical reaction to show the formation of its peroxide . why does the element impart colour to the flame . ?
Answer» Solution :SINCE the alkali metal IMPARTS yellow colour in the FLAME test , it must be sodium . It reacts with `O_(2)` to form a MIXTURE of mainly sodium peroxide `(Na_(2)O_(2))` with a small AMOUNT of sodium oxide `(Na_(2)O)` ` 4 Na + O_(2) overset(Delta) (to) 2 Na_(2)O, 2 Na_(2)O + O_(2) overset(Delta)(to) 2 Na_(2)O_(2)` or `"" 2Na + O_(2) overset(Delta)(to) Na_(2)O_(2)`
