Answer:
Boiling Point and Melting point = Condensation Point and Freezing Point
Explanation:
Such is easily seen on the 'Heating Curve for Water' (see attached). Note the regions that have zero slope. Trace back to y-axis of graph. These points are the phase transition temperatures for freezing (Iiquid => solid)/melting of ice (solid => liquid) and boiling of water (liquid => gas) / condensation (gas => liquid).
Note also, during phase change (heating or cooling), two phases will always be present (solid & liquid) or (liquid & gas) and experience 0 temperature change during the transitions (zero slope regions). The regions having slope values are heating or cooling of pure single phase form of the substance and do not represent phase change in those regions.

Answer:
Its outer electron is in the 3p-orbital which is slightly further from the nucleus and is shielded by the 3s-orbital and is therefore requires less energy to remove than the magnesium's outer electron which is closer and not as shielded.
Explanation:
Think of it as going to grab something. Are you going to want to grab the closest item or walk another 30 feet to get something else? Most would choose the shorter path and that is what these electrons do also.
