[Xe] 6s25d1
What else can I help you with?
Is the correct electron configuration for La (lanthanum) A. Kr6s25d1 B. Rn6s25d1 C. Cs6s25d1 D. Xe6s25d1?
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.
What is the ground state electron configuration of the element Lanthanum?
The ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
Why lagd and lu exhibt only 3 oxidation state?
Lanthanum (La) and lutetium (Lu) exhibit mostly the +3 oxidation state due to the presence of a stable electron configuration when they lose three electrons. Other oxidation states for these elements are less common due to higher ionization energies needed to change their electron configuration.
In which period and group does an electron first appear in an f orbital?
An electron first appears in an f orbital in the period 6 and group 3 of the periodic table. This is when the f sublevel starts to fill in elements such as lanthanum (La), which has a electron configuration [Xe] 5d1 6s2.
How do you valence electrons for La?
the valence electron of La is 3. because, La belongs to group IIIb and it is found in the outermost shell of the atom.
Is the correct electron configuration for La (lanthanum) A. Kr6s25d1 B. Rn6s25d1 C. Cs6s25d1 D. Xe6s25d1?
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.
What is the correct electron configuration for La (lanthanum)?
[Xe]6s25d1
What is the ground state electron configuration of the element Lanthanum?

What is the complete electron configuration for lanthanum?
[Xe] 5d1 6s2 or 2, 8, 18, 18, 9, 2
Why lagd and lu exhibt only 3 oxidation state?
Lanthanum (La) and lutetium (Lu) exhibit mostly the +3 oxidation state due to the presence of a stable electron configuration when they lose three electrons. Other oxidation states for these elements are less common due to higher ionization energies needed to change their electron configuration.
How many valence electron does lanthanum have?
Lanthanum has 2 valence electrons.
What is the noble gas configuration for Lanthanum?
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].
In which period and group does an electron first appear in an f orbital?
An electron first appears in an f orbital in the period 6 and group 3 of the periodic table. This is when the f sublevel starts to fill in elements such as lanthanum (La), which has a electron configuration [Xe] 5d1 6s2.
What is the atomic number of the first element to start filling an f sub-level?
The element cerium has a single electron in the 4f orbital. Its electron configuration is [Xe] 4f1 5d1 6s2.
What ion s formed by lanthanum?
The cation of lanthanum is La(3+).
How do you valence electrons for La?
the valence electron of La is 3. because, La belongs to group IIIb and it is found in the outermost shell of the atom.
