Statement 1: A low temperature implies that only low-energy states are occupied. Statement 2: A high temperature indicates that high-energy states are also occupied. (These statements are on p.27 of the textbook)

Using Boltzmann distribution formula show that these statements are true.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
