State the aufbau principle.

Chemistry
1 answer:
Inessa05 [86]3 years ago
5 0

Answer:

Explanation:

To show the sequence of electrons filling sublevels in an atom, the Aufbau's principle is one of the tenets that must be satisfied to write a proper notation.

  • Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies".
  • Note that based on this principle, we are not inferring that sublevels are filled in numerical order.
  • The patter of filling is shown below:

         1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f e.t.c

An adiabatic throttling valve expands an ideal gas. The internal energy of the ideal gas?
just olya [345]

The internal energy of the ideal gas is zero

The change in internal energy  for an isothermal process is zero.

An ideal gas has no interactions between particles, therefore no intermolecular forces.

pressure change at constant temperature does not change the internal energy.

Adiabatic throttling expansion has less work done and lower heat flow.

That lower the internal energy.

The temperature decreases during the adiabatic expansion

Hence the internal energy of the ideal gas is zero
