Q.

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:

  1. A

    Statement I is correct but Statement II is incorrect.

  2. B

    Statement I is incorrect but Statement II is correct.

  3. C

    Both Statement I and Statement II are correct.

  4. D

    Both Statement I and Statement II are incorrect.

Solution

Statement I is correct: an atom has equal protons and electrons, so net charge is zero.

Statement II is misleading: not every element's atoms are stable (many isotopes are radioactive), and emission of a characteristic spectrum only happens when atoms are excited, not as an inherent always-on property. So II is taken as incorrect.
