Answer:
Ions are atoms with a positive or negative charge.
Explanation:
Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.
The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.
The other options are not correct because of:
- <em>There are usually as many or more neutrons than protons.
</em>
- <em>Uncharged atoms are neutral.
</em>
- <em>The number of protons or neutrons does not affect the electric charge of the atom.</em>
- <em>Atoms that joined in fixed proportions can form molecules.</em>
Answer:
Dispersal
Explanation:
It should be understood that there was a point in time when the collard lizards were going into extinction. This is due to some certain human activities such as bush burning, which caused the death of this particular creature and others.
Therefore, this activity led to the dispersal of the remaining member of the population, which resulted to being isolated on a mountain.
