Which of the following electron "address" locations represents an electron with the highest energy? 6s2 4d7 4f1 5p6

c) 4f1

Explanation:

Based on Aufbau principle electrons in an atom or ion fill up such that the orbital of the lowest energy gets occupied first followed by those with higher energy. The energy ordering of atomic orbitals is therefore:

1s>2s>2p>3s>3p>4s>3d>4p>5s>4d>5p>6s>4f

The integers 1,2,3 .. represent the principal quantum number 'n'

s,p,d,f are the atomic orbitals each of which can accommodate a maximum of 2, 6, 10 and 14 electrons respectively.

As per the energy ordering, the 4f orbital is highest in energy and hence the single electron present in the 4f orbital represented by the configuration 4f1 will have the highest energy.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
