Q. Why is 4d written before 5s?
Even though 5s orbitals have a higher principal quantum number than 4d orbitals, (n = 5 compared to n = 4), they’re actually lower in energy. As a result, 5s orbitals are always filled before 4d orbitals. Filling up orbitals and writing electron configurations was so easy for atoms with less than 18 electrons!
Q. Is 4d higher energy than 5s?
4d has lower energy than 5s, and the electron configurations are written in order of increasing energy.
Q. Does 6s come before 4f?
Here, (n+l) of 6s orbital is 6 and that of a 4f orbital is 7 and hence 4f orbital is filled before 6s orbital.
Q. Which has more energy 5s or 4d?
First, the question is of chemistry category, but you have put it in physics. this is because of the higher energy state of 4d orbital. 5s orbital have less energy than 4d. So, the electrons go for 5s orbital instead of 4d orbital.
Q. Is 4d higher than 4p?
Explanation: In atoms of elements with more than one electron, each principal energy level is split into different sublevels. This is because the 4s orbitals have a greater electron density near the nucleus than the 4p orbitals, then come the 4d orbitals, and finally the 4f orbitals.
