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

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Answer 1

The Correct Option is C

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

This statement is correct. Atoms contain a nucleus with positively charged protons and a surrounding cloud of negatively charged electrons. When the number of protons equals the number of electrons, the atom has a net charge of zero, making it electrically neutral.

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

This statement is partially incorrect. Atoms are not always stable. Some isotopes of elements are radioactive and unstable. Atoms do emit characteristic spectra, but this happens when their electrons transition between energy levels, not because they are inherently stable. The spectrum is characteristic of the atom's electronic structure.

Therefore:

Statement I is correct.

Statement II is incorrect.
