Which of the following is an example of violating aufbau principle in filling electronic orbitals
1 answer:
Answer:
[Ne] 3s² 3d³
Explanation:
According to aufbau's principle of filling electronic orbitals, the sublevels with lower energies are filled up before those with higher energies.
One important to know about this principle is that sublevels do not fill in numerical order.
The order of filling is;
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f e.tc
From the given choices the wrong one is;
[Ne] 3s² 3d³
3p fills up before 3d;

water water water water water water water water 6
Answer:
True that in the preindustrial era, settlements were more likely to be near sources of surface water than in the industrial era. The main reason being that during the preindustrial era people were dependent mostly on irrigation. For irrigation people were dependent on surface water. This was the main and basic reason.
Answer:
A tundra is less humid than a desert
Explanation:
Answer:
The nucleus of the atom as suggested by "nuclear" chemistry. Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons. An excessive amount of protons or neutrons. Periodic table, table O, and table N. Personal opinion question. The atomic number. It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge). Protons ---- element. Random, self-generated. Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass. Neutrons and Gamma radiation. Gamma radiation. Electrons and Beta particles. To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element. The number of protons because they are what define the identity of an element. Goodluck!
