The subshells of 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 4f act like core orbitals. This understanding of the configuration of the atom helps us to understand why electrons and atoms behave the way they do.
Most orbitals are not circluar at all. This is because of the combined effects between attraction to the nucleus and repulsion form each other. Orbitals are not actually defined locations for the electron, but just the places they are most likely to be. Because of the aforementioned effects, the place they are most likely to be ends up as a shape whereby the balance, of the two forces of attraction and repulsion, is optimised.
electron pairs move away from each other to more electrostatically balanced positions
All have the same nuclear charge and consequently the same electron configuration.
Sodium chloride has got electron configuration of 2,8,1. Potassium chloride has got electron configuration of 2,8,8,1. They behave identically in almost all the chemical reactions. But then you have potassium chloride molecule inside the cell. You need to have sodium chloride molecules out side the body cell to make them survive. If you get intravenous injection of sodium chloride, nothing will happen to you. If you give intravenous injection of potassium chloride, you will die instantly. How body cells recognize the difference between sodium chloride and potassium chloride in no time is the big question mark.
There is no metal like you describe in your question. Hydrogen is in Group 1, but is not an alkali metal. It is a gas at standard temperature. It does rarely behave like an alkali metal, and it does have only one electron. Hydrogen is in Group 1 primarily because of its electron configuration, which is 1s1. All of the alkali metals also have one electron in their outermost s orbital.
Erwin Schrodinger proposed the modern atomic model, known as the "wave-mechanical" model. Essentially, he said that atoms behave like both waves and particles, and purported the concept of electron shells, subshells, and orbitals. Electrons are found on "shells" of charge outside the atom. These shells divide into subshells, which divide into orbitals.
Yes, chemical similarities exist between hydrogen and alkali metals; also the electron configuration has a parallel.
An electron model is a good approximation of the behavior of electrons in certain macroscopic phenomena, such as electricity and magnetism. It helps to explain how electrons move in a circuit or interact with magnetic fields. However, in more complex quantum phenomena, the electron model may not accurately represent the behavior of electrons.

Electrons behave like tiny magnets because they have a property known as spin. This spin generates a magnetic field around the electron, giving it magnetic properties. When electrons are in motion, their spin causes them to act like small magnets, aligning with an external magnetic field.
the power from te cord go on the metal so when you touch it you get shocked

Electron arrangement determines the chemical properties and reactivity of an element or compound. It governs how atoms interact with each other to form bonds, which influences their physical and chemical properties. Understanding electron arrangement helps predict how an element will behave in different chemical reactions and environments.
An electron cloud surrounding an atom is a visualization tool to allow for the discussion of atomic proberties. Since electrons behave with wavelike properties, the "cloud" is a representaion of the probability density of the electron's wavefunctions.
All have the same nuclear charge and consequently the same electron configuration.
Electron effective mass is a measure of how electrons behave in a material under the influence of an external force, such as an electric field. It describes the inertia of an electron in response to the force and is often used to model the electron's behavior as if it were a free particle with a certain mass.
