What is the electron configuration of Cd2+?

2015/11/12[Kr]4d^10 Your starting point here will be the electron configuration of a neutral cadmium atom. Cadmium, Cd, is located in period 5, group 12 of the periodic table and has an atomic number equal to 48. This means that a neutral cadmium atom will have a total of 48 electrons surrounding its nucleus. This also tells you that the Cd^(2+) cation, which has two electrons less than the Get price

1. Introduction

Cadmium is accumulated (50–70% of body burden) in the kidneys and liver, where it induces the production of metallothionein that binds approximately 80–90% of cadmium in the body [28]. There is little or no metabolism of cadmium, although it binds to various macromolecules and proteins [ 27 ]. Get price
