Question

write two general rules to help us to predict electronic configuration​

Answer 1

Answer:

ec

Explanation:

it has 4 shells

1 she'll have 2 electron 2 she'll have 4 electron 3 she'll have 6 electron 4 she'll have 8 electrons

Answer 2

Hund's law and Aufbau's principle helps us to predict electronic configuration.

• Hund's law : According to this law,in the electronic configuration of an element, all the subshells present in an orbital will be filled with single electrons in the first hand and then the double occupancy will happen by the remaining electrons.

• Aufbau's principle : According to this principle the electrons first enter in the lowermost energy level occupied orbital and goes into ascending order in terms of orbital energy levels.
