Atomic Structure Question 115
Question: Atoms consists of protons, neutrons and electrons. If the mass of neutrons and electrons were made half and two times respectively to their actual masses, then the atomic mass of $ _6C^{12} $ [NCERT 1982]
Options:
A) Will remain approximately the same
B) Will become approximately two times
C) Will remain approximately half
D) Will be reduced by 25%
Show Answer
Answer:
Correct Answer: D
Solution:
No change by doubling mass of electrons however by reducing mass of neutron to half total atomic mass becomes $ 6+3 $ instead of $ 6+6 $ . Thus reduced by 25%.
