Answer 2

La³ is having the electronic configuration is

1s², 2s², 2p⁶, 3s², 3p⁶, 3d¹⁰, 4s², 4p⁶, 4d¹⁰, 5s²,5p⁶ ,5d⁰, 6s⁰

Explanation:

• Lanthanum is an element with the symbol La and atomic number 57.

• Lanthanum electronic configuration is 1s², 2s², 2p⁶, 3s², 3p⁶, 3d¹⁰, 4s², 4p⁶, 4d¹⁰, 5s²,5p⁶ ,5d¹, 6s²

• itis a white soft and ductile silvery metal.

• It is a rare earth metal.

• The oxidation of lanthanum is +3

• It is the prototype of the lanthanide series and is called 4f elements because they have an incomplete 4f subshell.
