2. Click Pause (-). Elements can be classified as metals and nonmetals. Metals do not hold
on to their valence electrons very tightly, while nonmetals hold their electrons tightly.
Electron affinity is a measure of how tightly the valence electrons are held.
A. Try pulling an electron away from each atom. Based on this experiment, which atom
is a metal?
Which is a nonmetal?
B. Try moving an electron from the metal to the nonmetal. What happens?

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter
