How many electrons are in the highest energy orbital of the element copper?

Explanation:

According to the Aufbau principle, in the ground state of an atom or ion the electrons fill atomic orbitals of the lowest energy levels first, before filling the higher energy levels.

For example, atomic number of copper is 29 and its electronic configuration is

So, in copper the 4s energy shell is filled first because it has less energy as compared to 3d shell.

And, after filling of 4s orbital there occurs filling of 3d orbital. Since, there are 10 electrons in a 3d orbital of copper.

Thus, we can conclude that the highest energy orbital of the element copper contains 10 electrons.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

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.
