2 False…
The more volatile the higher it goes on the graph. The less volatile the lower it
Goes.
Answer:
C) F
Explanation:
Valence electrons are the electrons present in the outermost shell of an atom and have the highest energy level of an atom whereas electrons at ground state or lower orbitals have less potential energy.
This is so because <u>orbitals nearby nucleus are strongly bonded with the atomic nucleus and have less energy than an outermost shell.</u>
So, the potential energy states of an atom depend on the number of orbitals. In the given options fluorine with atomic number 9 has less number of orbitals that is 2 orbitals and valence electrons will be present in second orbitals, so fluorine will have the lowest average potential energy states.
Hence, the correct option is "C) F".
Answer:
There would be 3 temperature changes and 2 phase transitions
Explanation:
The temperature of the material would first increase from T0 to Tm (its melting point)- This is one temperature change.
It would the change from solid to liquid at its melting point Tm.- This is one phase transition.
Its temperature would then increase from its melting point Tm to its boiling point Tv -This is another temperature change.
It would then change from liquid to gas at its boiling point Tv - This is another phase transition.
Finally, its temperature would then increase from its boiling point to T(f) - This is the third temperature change.
So, there would be 3 temperature changes and 2 phase transitions
