[Xe]6s25d1
[Xe]6s25d1
Lanthanum has 2 valence electrons.
The noble gas configuration for Lanthanum is [Xe] 5d1 6s2. Lanthanum has 57 electrons, so the noble gas before it (Xenon - atomic number 54) has a configuration of [Xe].
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
1s2 2s2 2p6
B. Rn6s25d1. Lanthanum (La) has an atomic number of 57, so the electron configuration would be [Xe] 6s25d1. The noble gas right before La on the periodic table is Radon (Rn), hence the correct electron configuration for lanthanum is Rn6s25d1.
[Xe]6s25d1
The ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
[Xe] 5d1 6s2 or 2, 8, 18, 18, 9, 2

The correct full electron configuration for neon (Ne) is 1s2 2s2 2p6.
The noble gas configuration for Lanthanum is [Xe] 5d1 6s2. Lanthanum has 57 electrons, so the noble gas before it (Xenon - atomic number 54) has a configuration of [Xe].
No, the electron configuration is incorrect. The correct electron configuration for an element with 52 electrons would be Kr 5s2 4d10 5p6.
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
The electron configuration provided seems to be incorrect. The correct electron configuration for an element is based on the Aufbau principle, which governs the way electrons fill energy levels and sublevels. Double-check the electron configuration using the correct order of filling for orbitals.
