The process in which an unstable atomic nucleus emits charged particles and energy.
a
chemical reaction
b
radioactivity
c
covalent bonding
d
ionic bonding
b) radioactivity
The correct answer is b) radioactivity.
Radioactivity is the process by which an unstable atomic nucleus undergoes a spontaneous transformation, emitting charged particles (such as alpha or beta particles) and energy in the form of radiation. This process occurs in certain elements that have an excess of protons or neutrons in their nucleus, making them unstable. Through radioactive decay, these atoms try to reach a stable state by emitting particles and energy.
The correct answer is b) radioactivity.
Radioactivity is the process in which an unstable atomic nucleus emits charged particles and energy. This is a natural phenomenon that occurs in certain types of atoms, typically those with large nuclei that are not in a stable configuration. These unstable atoms are said to be radioactive.
To arrive at this answer, you can eliminate options a) chemical reaction, c) covalent bonding, and d) ionic bonding as they are all related to chemical bonding and interactions between atoms, rather than the release of charged particles and energy from an unstable atomic nucleus.
By understanding the definition of radioactivity and the characteristics of this phenomenon, you can conclude that the correct answer is b) radioactivity.
