Why is it Xe????????????????
Tamiku [17]

Answer:

Here's what I get.

Explanation:

Ba is element 56. Its electron configuration is

1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²

That's a lot of writing.

To lessen the work, chemists have developed the noble gas notation.

The core electrons of Ba (listed in boldface) have the same electron configuration as Xe, the noble gas found two atoms earlier in the Periodic Table.

Chemists replace the core electron configuration with the symbol of the corresponding noble gas.

The noble gas notation for Ba becomes

Ba: [Xe]6s².

What does the group number on the periodic table tell you about the electron configuration of a
jarptica [38.1K]

Answer:

The group number in the periodic table represents number of valence electrons of the elements in a certain group.

Explanation:

There are s, p, d, and f blocks, which you can see in periodic table

The s-block and p-block together are usually considered main-group elements, the d-block corresponds to the transition metals, and the f-block encompasses nearly all of the lanthanides (like lanthanum) and the actinides (like actinium)

There are three main principles, which may useful for you:

  • The Pauli exclusion rule basically says that at most, 2 electrons are allowed to be in the same orbital.
  • Hund’s rule explains that each orbital in the subshell must be occupied with one single electron first before two electrons can be in the same orbital.
  • The Aufbau process describes the process of adding electron configuration to each individualized element in the periodic table.

Hope this helps!
