Answer:
C. Potassium-19
.
Explanation:
Hello!
In this case, since isotopes are known be atoms of the same element with equal atomic number but different mass number, we can consider the case of carbon which has two natural occurring ones, carbon-12 and carbon-13 whereas carbon-12 has the greatest abundance. However, isotope notation may take two forms:
1. Symbol of the element followed by a dash indicating the mass number of the isotope, for instance: C-12, K-39, and so on.
2. Name of the element followed by a dash indicating the mass number of the isotope, for instance: Carbon-12, Potassium-39, and so on.
In such a way, the improper isotope notation is C. Potassium-19
, considering that A should be K-39 because atomic symbol of potassium is K, not k.

The resistance has a linear relationship with temperature because it increases as temperatures increases.
<h3>What is temperature?</h3>
Temperature refers to the activity (motion or thermal energy) in the atoms that form molecules.
The resistance of an electric conductor increases as the temperature increases since the thermal energy of subatomic electrons also increases.
In conclusion, the resistance has a linear relationship with temperature because it increases as temperatures increases.
