Question

Define Ionisation energy and explain why IE3>IE2>IE1

Answer 1

IONISATION ENERGY IS THE AMOUNT ENERGY REQUIRED TO EJECT AN ELECTRON FROM A NEUTRAL ISOLATED GASEOUS ATOM...

WHEN WE EJECT THE 1ST ELECTRON,IT IS KNOWN AS THE IE1,WHEN WE EJECT THE 2ND ELECTRON THEN IT IS KNOWN AS IE2& THE THIRD ONE IS KNOWN IS KNOWN AS IE3

IE3>IE2>IE3 BECAUSE WHEN U EJECT THE FIRST ELECTRON,IT THE SIZE OF ATOM SHRINKS,i.e,U REQUIRE MORE ENERGY TO EJECT THE 2ND ONE AND WHEN U TRY TO EJECT THE 3RD ONE,THE ATOM SHRINKS FURTHER RESULTING IN MORE ENERGY...

hope u mark as the brainliest answer
