How does the mass of an electron compare to the mass of a proton and a
tensa zangetsu [6.8K]

Answer:

C. The mass of an electron is much less than the mass of a proton or

a neutron.

Explanation:

When we compare the mass of an electron to that of proton or neutron, the mass of an electron is much less than the mass of a proton or a neutron.

Electrons are negatively charged particles in an atom

Protons are positively charged particles

Neutrons do not carry any charges.

  • The relative mass of an electron compared to that of a proton is \frac{1}{1840}
  • This is a very small value
  • Electrons generally have mass of 9.11 x 10⁻³¹kg
  • Protons weigh 1.67 x 10⁻²⁷kg
  • Neutrons weigh  1.68 x 10⁻²⁷kg

We can see that electrons have very small mass and this is why when calculating the mass of an atom, we use the sum of the number of protons and neutrons.

In which location would a free neutron from a decaying U-235 atom be most likely to cause another atom to go split?
Juliette [100K]

Answer:

The correct answer is option B

B. In a sample of enriched uranium

Explanation:

Nuclear fission is a nuclear reaction whereby large nucleus of an atom is break down into smaller parts lighter nuclei or daughter nuclei and release large amount of energy, due to the large amount of energy there are alot of heat released.

During the process large nucleous is bombarded by the neutrons, as a result of this the nucleous becomes disintegrated because it's unstable and their is production of lighter nuclei as well as neutrons and energy.

When the U -235 particles are compacted together there result a high energy neutron which can bombard another Uranium - 235 molecule in the region. uranium is enriched with more of the fissile uranium isotope, then when it is enriched it can be used to make atomic reactors and explosives like bombs.
