Which sublevels of the third energy level are filled in the element krypton?
In the element krypton, the third energy level has 3 sublevels: s, p, and d. The s and p sublevels are filled first before the d sublevel. This means that in krypton, the 4s and 4p sublevels are filled, while the 4d sublevel remains empty.
What is the basis for exceptions to the aufbau diagram?
Exceptions to the aufbau principle occur due to the repulsion between electrons in the same orbital. This can cause certain elements to have lower energy by placing an electron in a higher energy orbital. Additionally, electron-electron interactions and exchange energy play a role in determining the actual electron configurations of some elements.
What are stable electron configurations most likely to contain?
Stable electron configurations are most likely to contain filled energy levels or filled subshells. These configurations generally follow the octet rule or duet rule, depending on the element. Additionally, stable electron configurations may contain configurations with a full valence shell of electrons.
The sequence in which energy sublevels are filled is specified by?
The sequence in which energy sublevels are filled is specified by the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level to the highest, following the order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, and so on.
Which elements have a partially filled p subshell?
p-block elements have partially filled p-subshell. It is not completely filled.
What are the metals with their s and d sub levels partially full?
Metals with their s and d sublevels partially filled are in transition metals group. For example, in the 4th period, scandium (Sc) has the electron configuration [Ar] 3d1 4s2 with partially filled 3d and filled 4s sublevels.
Which sublevels of the third energy level are filled in the element krypton?
In the element krypton, the third energy level has 3 sublevels: s, p, and d. The s and p sublevels are filled first before the d sublevel. This means that in krypton, the 4s and 4p sublevels are filled, while the 4d sublevel remains empty.
How many elecrtons shells would be filled by a neutral xenon atom?
The first 3 energy levels are filled, the 4s and 4p and 4d sublevels are filled, and the 5s and 5p sublevels are also filled. So only the first three energy levels are completely filled. The fourth and fifth energy levels are partly filled. The electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6 or [Kr]4d105s25p6.
What outer sublevels are completely filled in a noble gas?
s orbital for helium and p orbitals for other noble gases.

Because their outermost energy level are only partially filled some elements are highly?
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
Energy-favorable states for the d sublevel are when it contain electrons?
Energy-favorable states for the d sublevel occur when it is half-filled or fully-filled with electrons. This is because half-filled and fully-filled d sublevels have lower overall energy due to electron-electron repulsions being minimized. Additionally, these configurations result in greater stability and lower energy.
The sequence in which energy sublevels are filled is specified by?
The sequence in which energy sublevels are filled is specified by the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level to the highest, following the order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, and so on.
Which elements have a partially filled p subshell?
p-block elements have partially filled p-subshell. It is not completely filled.
What is an element with 7 valence electrons and 4 energy levels?
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
Same elements are highly what because their outermost energy levels are only partially filled?
reactive
