⏺ The unpaired electrons in Al and Si are present in 3p orbital. Which electrons will experience more effective nuclear charge from the nucleus?​

Answer 1

Answer:

ExplanationNuclear charge increases as we go from left to right in a periodic table

Nuclear charge is defined as the net positive charge experienced by an electron in a multi-electron atom. Silicon has greater nuclear charge(+14) than aluminium (+13). Hence the unpaired 3p electron in case of silicon will experience more effective nuclear charge.
