Calculation of Radial and Angular Nodes

JEE Main asked Calculation of Radial and Angular Nodes 8 times in 8 of the 108 shifts Lumi analysed, in 2021, 2022, 2023, 2024 and 2026. It belongs to Quantum Numbers, in Structure of Atom (Chemistry). The longest wait between two years asking it was 2 years. In 2021 and 2022 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022, 2023, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
