What element completes the 4s sublevel?
The element that completes the 4s sublevel is calcium (Ca). It has the atomic number 20, which means it has 20 electrons. The electron configuration of calcium is (1s^2 2s^2 2p^6 3s^2 3p^6 4s^2), indicating that the 4s sublevel is filled after the 3p sublevel.
What are the sublevel of Fe?
Iron (Fe) has the electron configuration of [Ar] 3d^6 4s^2. The sublevels for iron include the 4s sublevel, which is filled before the 3d sublevel, and the 3d sublevel, which contains six electrons. Thus, the relevant sublevels for iron are 4s and 3d.
Which has 2 electron in the 4s sublevel?
Ca
When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
In the ground state the 3d and 4s sublevels of the chromium atoms atomic number 24 are represented as?
In the ground state of a chromium atom (atomic number 24), the electron configuration is [Ar] 3d^5 4s^1, with 5 electrons in the 3d sublevel and 1 electron in the 4s sublevel. This configuration is due to the stability achieved by half-filling the 3d sublevel before completely filling the 4s sublevel.
What element completes the 4s sublevel?
The element that completes the 4s sublevel is calcium (Ca). It has the atomic number 20, which means it has 20 electrons. The electron configuration of calcium is (1s^2 2s^2 2p^6 3s^2 3p^6 4s^2), indicating that the 4s sublevel is filled after the 3p sublevel.
Why does an electron occupy the 4s orbital before the 3d orbit?
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
What element has 2 electrons in the 4s sublevel?
Calcium is the element that has 2 electrons in the 4s sublevel.
What element completes the 7s sublevel?
The element that completes the 7s sublevel is radium, with the electron configuration 7s2.
What are the sublevel of Fe?
Iron (Fe) has the electron configuration of [Ar] 3d^6 4s^2. The sublevels for iron include the 4s sublevel, which is filled before the 3d sublevel, and the 3d sublevel, which contains six electrons. Thus, the relevant sublevels for iron are 4s and 3d.
Which elements have 2 electrons in the 4s sublevel?
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).
Which has 2 electron in the 4s sublevel?
Ca
Which element has 2 electrons in the 4s sublevel?
Ca
What elements completes the 2s sublevel?
The 2s sublevel can hold a maximum of 2 electrons.
When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
Why are the valence electrons of calcium in the 4s orbital not the 3d orbital?
Valence electrons occupy higher energy levels first before moving to lower energy levels, according to the aufbau principle. In calcium, the 4s orbital has lower energy than the 3d orbital, so valence electrons fill the 4s orbital first before the 3d orbital.
What element have 2 electrons in the 4s sublevel?
Ca
