Chlorine is more reactive than argon, because argon is not reactive at all. Chlorine only has to gain 1 valence electron
All atoms that are considered as alkali metals have one valence electron on the outermost shell.
Answer is: temperature must be less than 140 K.
Gibbs free energy
(G) determines if reaction will proceed spontaneously. <span>If
the value of G is a negative, the reaction is spontaneous. <span>ΔG = ΔH - T·ΔS.
</span></span>ΔH = -70.00 kJ.
ΔS = -0.500 kJ/K.
-70 kJ = T · (-0.5 kJ/K).
T = -70.00 kJ ÷ (-0.500 kJ/K).
T = 140 K.
Answer:
Explanation:
The names Px, Py and Pz, indicate the orientation of the orbital in space. The key difference between Px Py and Pz orbitals is that Px orbital has two lobes oriented along the x-axis and Py orbital has two lobes oriented along the y-axis whereas Pz orbital has two lobes oriented along the z-axis.
Mike would be right, since there are only 3 electrons in the shell, if shows that there are 3 protons. Lithium is the only element with 3 protons
