Atoms

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.Both Statement I and Statement II are incorrect
  2. B.Statement I is correct but Statement II is incorrect✓
  3. C.Statement I is incorrect but Statement II is correct
  4. D.Both Statement I and Statement II are correct

Solution

Atoms are neutral because they carry equal positive and negative charge — Statement I is correct. Atoms emit their characteristic spectrum only when excited, not simply because they are stable — Statement II is incorrect.
