In which area of the periodic table should quan look to find materials that would be suitable for making this jewelry

A) Among the metals

It is this because metals are the only well malleable elements, metalloids aren't as malleable, nonmetals aren't usually useful in this sense and gases are nonmalleable as well

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
