QUESTION

Given that: atomic number = 19 density = 0.86g/cm3 atomic weight = 39.1amu Lattice constant = 0.2nm BCC metal a. what is the electron configuration?

Given that:

atomic number = 19

density = 0.86g/cm3

atomic weight = 39.1amu

Lattice constant = 0.2nm

BCC metal

a. what is the electron configuration? how many free electrons are available?

b. Assuming free-electron model, what is the highest energy that electrons can have in the sample?
