What does chemical reactivity have to do with electron configurations and energy levels?

The electronic configuration of an element gives an idea about its reactivity.
The elements having a completely filled outermost orbit (or shell) will be chemically inert (non-reactive). For example, the outermost shell in the case of helium (He), neon (Ne) and argon (Ar) are completely filled as shown below. As a result, helium, neon, and argon are chemically inactive (or inert). These elements do not form compounds with other elements.
Because of this chemical inactivity, these gases are called as noble gases (earlier these were called inert gases).
The elements containing only one or seven electrons in their outermost shell show greater chemical reactivity, i.e., such elements react very fast with other elements. For examples, sodium and chlorine having the follows electronic configurations are highly reactive.
Sodium 2, 8, 1 ---- Here, the outermost shell has been one one electron: one more than the completely filled shell.
Chlorine 2, 8, 7 ----- Here, the outermost shell has seven electrons: one less than that required to fill the shell completely.

∙ 12y agoIt depends how many electrons are in their outer ring called valence electrons. They want to have a full outer ring so they will become more reactive if they only need a few. For example Chlorine, Cl, needs one electron so it is very reactive. An element like neon that already has a full outer shell is not very reactive because it has no need to get more electrons.

What are the rules for reactivity of metals on the periodic table?
The reactivity increases with increasing numbers of electron shells (energy levels).
Is true about the electron configurations of the noble gases?
the elections with the highest energy are in an f sub level. your welcome :))
How do electron configuration of noble gases give them shared properties?
The reason for the noble gases gases' electron configurations to allow them to have a similar property of having a low reactivity is because they all have a full set of electrons in their outermost energy level.
What happens when an excited electron is passed to an electron acceptor in a photosystem?
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
Why is valence electron important in chemical bonding?
Valence electron is important in chemical bonding because it has chemical energy so you can eat and it also is because it is.
How many energy levels do the most stable electron configurations have?

How is the chemical symbol of an element determined-?
Usually the first and second letter of element can determine it's chemical symbol.
What is an electron in the outermost energy level of an atom?
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
Which subatomic particle contains the energy stored in the chemical bonds?
Electron. ---------------------------------------------------------------------- The electron itself does not store energy. It is the position of the electron in relation to atomic nuclei that contains the chemical bond energy.
How does ionization energy affect the reactivity of metal?
Ionisation energy determines the ability to loose electron. It tells the amount of energy changes in the process.
What do the reactants of a chemical reaction have?
They have a specific reactivity and the reaction need an activation energy.

What is HOMO and LUMO?
HOMO stands for highest occupied molecular orbital, representing the highest energy level at which an electron can be found in a molecule. LUMO stands for lowest unoccupied molecular orbital, representing the lowest energy level at which an electron can be promoted to in a molecule. These orbitals are important in understanding chemical reactivity and properties.
What are stable electron configurations most likely to contain?
filled energy sublevels
What chemical energy form from electron flow?
Well, Chemical energy is not formed by the flow of electron. The flow of electrons is responsible for the generation of electricity. It is not possible to store electrical energy in its original form. So this electrical energy is stored in the form of chemical energy in case of a battery (Electrical energy is stored in the chemicals of a battery thus converting into chemical energy.) Therefore, Electron flow generates only electricity and no chemical energy is formed.
