It's not C and D because they are asking you for kelvin, and it's not B because the idea of kelvin it's that the number is never going to be a negative. So when you want to convert C to K just add 273. 40+273= 313
Answer from: Quest
since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
Answer from: Quest
we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
