Answer 2

hii, your answer is here -
Lithium, sodium and potassium are easily cut with a blade or a knife. the freshly cut surfaces are silvery and shiny, but quickly turn dull as the metal reacts with oxygen in the air. the group 1 metals react vigorously with oxygen to form metal oxides.
When sodium was heated and put into a jar full of oxygen if generates a lot of heat energy and light, when the reaction was over sodium oxide (Na2O) was left. the white powder in the jar was sodium oxide after the reaction between sodium and oxygen.
