Answer : The electron configurations consistent with this fact is, (b) [Kr] 4d¹⁰
Explanation :
Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.
Number of electrons in an atom are determined by the electronic configuration.
Paramagnetic compounds : They have unpaired electrons.
Diamagnetic compounds : They have no unpaired electrons that means all are paired.
The given electron configurations of Palladium are:
(a) [Kr] 5s²4d⁸
In this, there are 2 electrons in 's' orbital and 8 electrons in 'd' orbital. From the partial orbital diagrams we conclude that 's' orbital are paired but 'd' orbital are not paired. So, this configuration shows paramagnetic.
(b) [Kr] 4d¹⁰
In this, there are 10 electrons in 'd' orbital. From the partial orbital diagrams we conclude that electrons in 'd' orbital are paired. So, this configuration shows diamagnetic.
(c) [Kr] 5s¹4d⁹
In this, there are 1 electron in 's' orbital and 9 electrons in 'd' orbital. From the partial orbital diagrams we conclude that 's' orbital and 'd' orbital are not paired. So, this configuration shows paramagnetic.
Answer:
During chemical reactions are broken and to form new substances with different properties, but mass is still .
"Aristotle," thought that everything was made from "earth", "air", "fire" and "water".
Option: D
Explanation:
"Aristotle" was against to "Atomic theory" so he believed that all the things were made from earth, air, fire and water called "four classical elements". These are "four classical elements" responsible for creating all the things in "terrestrial spheres". "Aristotle" started believing that all many of the little substances were "made up" of these "four classical elements" earth, air, fire and water. But "Aristotle" views on "elements" went wrong. "Aristotle" also grasped that "heavens" are created by using "weightless" and "unchangeable" the "fifth element" called "Aether".
