Answer:
The correct options are: a. the number of additional neutrons of an isotope is too large; d. the number of additional neutrons of an isotope is too small
Explanation:
The chemical elements that have the same number of protons in the nucleus but different number of neutrons are known as isotopes. Isotopes can be stable or unstable.
The isotope having an unstable nucleus, due to the presence of additional neutrons in the nucleus of the atom, is known as a radioisotope.
Also, chemical elements that have atomic number greater than 83 have unstable nuclei and thus they are called radioisotopes.
Answer with Explanation:
"Navigators" are people responsible for telling the position of an object in response to its location. It tells which direction the<em> vessel, vehicle or aircraft</em> needs to follow. In order to do this, they need to be equipped with maps. Maps will allow them to function, since it is their<em> "lifeline."</em> This means that <u>navigators relies on maps</u> in order to know more about the different locations in the area. Without maps, <em>they won't be able to know the correct direction from one point to another.</em> This will also render their navigational skills useless.
