It is known that atoms contain protons, neutrons and electrons. If the mass of neutron is assumed to be half of its original value whereas that of electron is assumed to be twice of this original value. The atomic mass of 6C12 will be (A) Twice (B) 75 % less (C) 25 % less (D) one-half of its

Tardigrade Admin · Accepted Answer

A = P + n A = 12 n = 12-6 A = Z+n Z = 6 n = 6 = (9/12) ×100=75 % =100-15 =25 % less mass

Q. It is known that atoms contain protons, neutrons and electrons. If the mass of neutron is assumed to be half of its original value whereas that of electron is assumed to be twice of this original value. The atomic mass of $_{6} C^{12}$ will be

Twice

$75%$ less

$25%$ less

one-half of its

A = P + n
A = 12
n = 12-6
A = Z+n
Z = 6
n = 6
$= \frac{9}{12} \times 100 = 75% = 100 - 15$
$= 25%$ less mass

25% less

one-half of its

A = P + n A = 12 n = 12-6 A = Z+n Z = 6 n = 6 =129​×100=75%=100−15 =25% less mass
