I am pretty sure its Pd (Palladium)
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.
zero - after the 4s orbitals are filled at Calcium, the 3d orbitals start to fill - not until Gallium do the 4p orbitals start to fill.
Molybdenum (Mo) has a configuration of [Kr] 5s^1 4d^5. Therefore, it has 5 4d electrons.
The element that forms a +3 ion with the electron configuration Kr 4d^6 is osmium (Os). Osmium typically forms a +3 ion by losing three electrons from its outermost 6s and 5p orbitals, resulting in the electron configuration Kr 4d^6.

The notation "5s² 4d¹⁰ 5p³" represents the electron configuration of an element in the periodic table. It indicates that the element has two electrons in the 5s subshell, ten electrons in the 4d subshell, and three electrons in the 5p subshell. This configuration corresponds to the element Antimony (Sb), which is found in group 15 of the periodic table and has an atomic number of 51.
The valence electrons fill in 4d orbital The electron configuration of yttrium is [Kr]4d15s2.
since it is in period 5 it contains 4d and 3d levels which both hold 10 electrons each. so therefore I (53) has 20 d electrons
zero - after the 4s orbitals are filled at Calcium, the 3d orbitals start to fill - not until Gallium do the 4p orbitals start to fill.
The electronic configuration of technetium is [Kr] 4d^5 5s^2. This means that technetium has 5 electrons in its 4d orbital and 2 electrons in its 5s orbital.
In iodine (I), the electron configuration is [Kr]5s²4d¹⁰5p⁵. This means that there are 10 electrons in the 4d orbital.
Molybdenum (Mo) has a configuration of [Kr] 5s^1 4d^5. Therefore, it has 5 4d electrons.
There are 10 electrons in the 4d subshell of the ground state of Xenon.
The element that forms a +3 ion with the electron configuration Kr 4d^6 is osmium (Os). Osmium typically forms a +3 ion by losing three electrons from its outermost 6s and 5p orbitals, resulting in the electron configuration Kr 4d^6.
The element with atomic number 47 is silver (Ag). In its neutral state, the electron configuration of silver is [Kr] 4d^10 5s^1. This means the 4d subshell is being filled by the electrons of silver.
