Question

Rutherford's nuclear model of the atom (1) is the currently accepted atomic model with no revisions (2) explains the unique emission spectra of different elements (3) does not account for the stability of most atoms since accelerating electrons would quickly lose energy and fall into the nucleus, causing the atom to collapse. (4) incorporated the first discovered subatomic particle, namely the proton ame. This red color is produced when During a flame test, a lithium salt produces a characteristic red fl electrons in excited lithium atoms (1) return to lower energy levels within the atoms (2) move to even higher energy levels within the atoms (3) àre lost by the atoms (4) are gained by the atoms

Explanation / Answer

Ans.1) Sice Rutherford said that according to Maxwell's theory any accelerating charged particles emits certain radiations & thus finally it loses all its energy & ultimately falls down in the nucleus. Thus Rutherford's atomic model couldn't explain the stability of the atom.

So option (3) will be correct.

Ans. 2) Whenever electrons fall from higher energy levels to lower energy levels they emit certain radiations, & thus atom shoes shoes certain Colors depending wavelength of the light radiation being emitted.

Thus lithium shows red colour in the flame test.

So option (1) will be correct.
