Who developed idea of electron shells?
Magnetism
What is the overall of an atom?
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.
Who developed the idea of electron shells also called orbit shells?
Niels Bohr
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
What is the shell of the highest energy electron in uranium?
The seventh electron shell.
What did knoll and ruska contribute to science?
They proposed the term of electron microscope and they developed the idea of electron lenses into a practical reality and demonstrated electron images taken on the instrument
What is the electron shell arrangement of caesium?
The electron shell arrangement of Ceasium is 2.8.8.18.18.1
Are valence electrons located in the electron cloud?
The outermost shell of an electron is called the valence shell. This shell may or may not have electrons.The valence shell is a part of the electron cloud.So your answer isYes, the valence electrons are located in the electron cloud.
When an alkali metal reacted with a non metal what happens to the loan outer shell electron?
The electron outside the shell donate its electron to the one inside the shell
Is nickel electron shell full or not full?
nickel's outside electron shell is not full.
Who developed the idea of electrons shells also called orbital shell's?
Albert Einstein albert Einstein
What is the Electron confirguartion of Iron?
Iron has 26 electrons in total. the first electron shell has 2 electrons, the second electron shell has 8 electrons, the third electron shell has 14 electrons and the final shell of iron(Fe) has 2 electrons.
