What is the tendency of electron to enter orbitals of lowest energy first?
Nature prefers low energy. It is thus energetically favorable to do so.
Why is the Aufbau Principle also known as the build-up principle?
The principle was named by a German speaker who called it Aufbau. "Buildup" is the usual translation of Aufbauinto English.
Is each orbital has at most two electrons the aufbau principle?
This is usually called the "Pauli Exclusion Principle".
What year was the aufbau principle discovered?
1920
Who stated that an electron occupies an orbital with the lowest energy level first before it will occupy a higher one?
If you are referring to the Aufbau Principle, than I believe it was the Danish physicist Niels Bohr who discovered it around 1920. However, instead of being named after a person, it came from the German phrase Aufbauprinzip which literally translates to "building-up principle."
Which element in the fourth period is an exception to the aufbau principle?
The element in the fourth period is an exception to the Aufbau principle is Cr. Each period in the periodic table corresponds to a principal energy level.
What element is the exception to the aufbau principle?
chromium and copper.
Does aufbau principle works with every element?
Every element besides chromium and copper.
Who discovered the aufbau's principle?
Bohr &Stoner suggested aufbau principle

Why Aufbau principle is not valid for multielectron system?
It is valid
What the Aufbau principle state?
The principle is: electrons fill first the lower energy levels.
The structure of each successive element is found by adding one proton to the atom's nucleus and one electron to the lowest-energy orbital availble?
Aufbau Principle
