2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
The 4s orbital has the greatest shielding effect because it is the closest to the nucleus and experiences less shielding from inner electrons compared to the 4p, 4d, and 4f orbitals. This means that electrons in the 4s orbital are held less tightly by the nucleus and are more easily removed.
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p
The 4s energy level has the lowest energy among the options provided. In the aufbau principle, electrons fill lower energy levels before moving to higher energy levels. Therefore, the 4s orbital is filled before the 4p, 4d, and 4f orbitals.
16 orbitals in the 4th energy level. One s orbital, three p orbitals, five d orbitals, seven f orbitals Elements where the 4th principal energy level are filled are:- period 4 4s and 4p (starting with potassium) period 5 4d starting with Yttrium Lanthanides 4f starting with cerium
The 5s orbital has a lower energy level than the 4d or 4f orbitals in a rubidium atom, according to the aufbau principle. Electrons fill orbitals starting from the lowest energy level to the highest energy level. This is why the electron fills the 5s orbital before the 4d or 4f orbitals in a rubidium atom.

The 4s orbital has the greatest shielding effect because it is the closest to the nucleus and experiences less shielding from inner electrons compared to the 4p, 4d, and 4f orbitals. This means that electrons in the 4s orbital are held less tightly by the nucleus and are more easily removed.
The 4f subshell has higher energy compared to the 4s, 4p, and 4d subshells. This is due to the increased screening effect and poor shielding of the nuclear charge by intervening 4d and 4p electrons. The 4f subshell is further away from the nucleus, leading to higher energy levels.
Tungsten (W) has an atomic number of 74, which means it has 74 electrons. Its electron configuration is [Xe] 4f^14 5d^4 6s^2. The 4d subshell is not occupied in tungsten; instead, the 5d subshell contains the electrons. Therefore, tungsten has zero 4d electrons.

The order of electron orbitals following the Aufbau principle is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p. Electrons fill the orbitals in increasing energy levels.
3 nodes in 4f
The possible values for a 4f sublevel are 14. This means there can be a maximum of 14 electrons in a 4f sublevel.
