Statement-I: Be and Mg do not respond to flame test while Ca, Sr and Ba give characteristic colours golden red, crimson and apple green respectively.Statement-II: In Bunsen burner flame, electrons of valence shell get excited by absorption of energy. When electrons return to their original state the radiations appear in visible spectrum and colour appears.
