Cadmium (Cd) has 48 electrons in total. It has configurations of 2, 8, 18, 18 and 2 electrons in its electron shells. This means that cadmium has 2 electrons in its 5s orbital.
In a neutral zinc atom, there are 2 electrons in the 4d orbital and 2 electrons in the 4s orbital. Therefore, there are no 5s electrons in a zinc atom.
In the Rb atom, the electron configuration is [Kr]5s^1. This means there is 1 electron in the 5s sublevel of the Rb atom.
Cadmium (Cd) has 48 electrons, and its electron configuration is [Kr] 4d10 5s2. This means that the core electrons in cadmium are those in the inner shells, which are the 36 electrons from the noble gas krypton (Kr). Therefore, cadmium has 36 core electrons.
Technetium has 43 protons and electrons.
There are 2 electrons in the highest occupied energy level of a neutral strontium atom, as the electron configuration of strontium is [Kr]5s^2.
In a neutral zinc atom, there are 2 electrons in the 4d orbital and 2 electrons in the 4s orbital. Therefore, there are no 5s electrons in a zinc atom.

There are 2 electrons in the outermost shell of strontium. Strontium has an electron configuration of [Kr] 5s^2, indicating that it has two electrons in its outermost shell.
In iodine (I), the electron configuration is [Kr]5s²4d¹⁰5p⁵. This means that there are 10 electrons in the 4d orbital.
Antimony (Sb) has an atomic number of 51, and its electron configuration is [Kr] 5s² 4d¹⁰ 5p³. In the Sb³⁺ oxidation state, it loses three electrons, typically from the 5p and 5s orbitals, resulting in the configuration [Kr] 4d¹⁰. Consequently, Sb³⁺ has no unpaired electrons, as all its electrons are paired in the filled 4d subshell.
A strontium atom has the atomic number 38, which means it has 38 electrons. The electron configuration of strontium is [Kr] 5s², indicating that its outermost shell (the 5s subshell) is fully filled with 2 electrons. Since all the electrons in strontium are paired, it has zero unpaired electrons.
Rubidium has one valence electron in the 5s orbital.
Cadmium (Cd) has 48 electrons, and its electron configuration is [Kr] 4d10 5s2. This means that the core electrons in cadmium are those in the inner shells, which are the 36 electrons from the noble gas krypton (Kr). Therefore, cadmium has 36 core electrons.
