Atomic Models & Alpha-Particle Scattering
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.
Show answer and solution
Answer: (c)
- Statement I: an atom has equal positive (nuclear) and negative (electronic) charge, so it is neutral. True.
- Statement II: this is the experimental fact (NCERT) every atomic model must explain: atoms are stable and each element emits its own line spectrum. True.
- So both statements are correct, which is option (a).
