Yttrium (Y) has an atomic number of 39, which means it has 39 electrons. Its electron configuration is [Kr] 5s² 4d¹, indicating that there is one 4d electron in yttrium. Therefore, the number of 4d electrons in Y is 1.
Molybdenum (Mo) has a configuration of [Kr] 5s^1 4d^5. Therefore, it has 5 4d electrons.
Yes. Magic Planet as XD theater, "the first 4D theatre in the UAE."
In a 4d orbital, the number of radial nodes can be determined using the formula ( n - l - 1 ), where ( n ) is the principal quantum number and ( l ) is the azimuthal quantum number. For a 4d orbital, ( n = 4 ) and ( l = 2 ). Therefore, the number of radial nodes is ( 4 - 2 - 1 = 1 ). Thus, a 4d orbital has one radial node.
Yes Zr (atomic number 40) is the first transitional element in period 5 ('4d-block' metals).
The element with three 4d electrons is ruthenium (Ru), which has an atomic number of 44. The 4d sublevel can hold a maximum of 10 electrons, so with only three electrons, ruthenium has a partially filled 4d orbital.

The symbol of the first element to have an electron in the 4d sublevel in its ground state is Yttrium, symbolized as Y, with the electron configuration [Kr] 4d^1 5s^2.
8 - 4d = 12-4d = 4d = -1
d = 2
4d is time...any moving object is 4d
