Why electrons are removed first from 5d than 4f orbital in lanthanides?

They are further away from the nucleus and easier to remove (requires less energy), i.e. first ionization is less.

How do you check paramagnetism and diamagnetism?
First make the m.o (molecular orbital) diagram. If the electrons are paired in an orbital then it is diamagnetic . If the electrons are not paired then it is paramagnetic.
What are the first electrons to be removed when d-block elements form ions?
the 4s electrons are removed first.
The number of electrons in the first orbit?
The first orbital has only an s orbital, which has room for 2 electrons. The second orbital has s and p orbitals, which have room for 2 and 6 electrons respectively. The 3rd orbital has s, p, and d orbitals, which have room for 2, 6, and 10 electrons respectively. Hope that helps
How many electrons can occupy a single molecular orbital?
Every orbital is different. 2 can occupy the first orbital then 8 can occupy mostly the rest. When you start getting really low on the periodic table orbitals start holding 16, but not till u get really low
How many electrons are in the first orbital shell in the element neon?
There are two electrons in the first shell of neon. Its complete electronic configuration is 2,8
In an atom the first orbital is complete when it has how many electrons?
Any orbital is complete when it contains 2 electrons.
Noble-gas electron configuration Pt?
[Xe] 4f^14 5d^8
How many electrons live in the first orbital?
2 electrons.
Why does 4s orbital start filling while 3p orbital is empty?
The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.
What is the Bohr configuration for chlorine?
17 protons and 18 neutrons in the nucleus 2 electrons in the first orbital. 8 electrons in the second orbital. 7 electrons in the third orbital.
How many outer orbital electrons is found in an atom of Be?
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
How many total electrons does an atom possess if it has the first two electron orbitals completed?
4 electrons. First orbital is the 1s which has 2 electrons. Second orbital is the 2s which has 2 electrons.
Do the first orbital have to be full before placing electrons in the next orbital?
Yes
Is Q the inner orbital for electrons?
No, Q is the outermost orbital. K is the first one.
How many electrons are in the first orbital of an atom?
there are 2
Which orbital is rhodium's last electron in?
If you are filling in the electrons it will be in the 4d orbital. If you are removing electrons the first to come out is in the 5s electrons since transition metals lose 's' electrons before 'd' electrons
How do you check paramagnetism and diamagnetism?
First make the m.o (molecular orbital) diagram. If the electrons are paired in an orbital then it is diamagnetic . If the electrons are not paired then it is paramagnetic.
