Answer:
-272.604 °C
Explanation:
The metals can conduct electricity, but this conduction has some resistance, and there're dissipations in the energy during the conduction. Some material has the ability, at very low temperatures, to conduce electricity without the resistance. This ability is called superconducting.
The mK corresponds to the miliKevin, and 1 K = 1000 mK, thus, the temperature in Kevin is 0.546 K.
T(K) = T(°C) + 273.15
T(°C) = T(K) - 273.15
T(°C) = 0.546 - 273.15
T(°C) = -272.604 °C

Actually Welcome to the concept of Atomic Structure.
Since, We all know that, To draw any Electron-Dot Structure, we always have to know the exact Number of valence or free electrons of any atom or molecule, hence
The Correct Answer is :-
D. Number of valence electrons.
Answer:
C. Be in the same group
Explanation:
Most elements in the same group have similar properties.
The answer is 7/10 but if you want it in decimal for it is 0.7
