Question

Given below are two statements:

Statement $I$: Atoms are electrically neutral as they contain equal number of positive and negative charges.

Statement $II$: Atoms of each element are stable and emit their characteristic spectrum.

In the light of the above statements, choose the most appropriate answer from the options given below.

✓

Answer

Statement $I$ is true as atoms are electrically neutral because they contain equal number of positive and negative charges.

Statement $II$ is wrong as atom of most of the elements are stable and emit characteristic spectrum. But this statement is not true for every atom.
