Question

What does the group number on the periodic table tell you about the electron configuration of a

Answer 1

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!
