Answer: it’s B
Explanation:
True
Explanation:
Lead is the stable form of uranium 238. Lead-206 is a product of radioactive decay of unstable uranium 238 isotope.
- Atomic nucleus have a specific neutron/proton ratio that ensures their stability.
- Nucleus whose proton/neutron ratio is different from that of its stability ratio will be unstable and split into other nuclei.
- This splitting is accompanied with emission of small particles of matter and or electromagnetic radiation.
- Unstable uranium -238 undergoes 14 radioactive decays to produce a stable form which is Pb-206

The objects that could hit the atoms in the model shown are neutrons.
<h3>What is a chain reaction?</h3>
A chain reaction is a reaction that is able to sustain itself. In this case, when the neutrons collide with the fissile nucleus, more neutrons are produced which collides with more fissile nuclei thereby sustaining the reaction.
Thus, the objects that could hit the atoms in the model shown are neutrons.

In a permanent magnet, a magnetic field is produced by the composite motions of electrons in geometrically aligned atoms.
A magnetic field is characterized by poles called north and south. Magnetic polarity refers to the orientation of these poles in space.
