Flauer [41]

The valence electrons are located in an atom's outermost energy level

<h3>Further explanation  </h3>

In an atom, there are levels of energy in the shell and subshell  

This energy level is expressed in the form of electron configurations.  

Electrons fill the orbitals based on the Aufbau principle, namely the filling of electrons starts from the lowest energy level

  • Electron dots

Usually used in describing Lewis structures, placed around the element

  • Quantum electrons

Each orbital in an atom consists of 4 quantum numbers  : n, l, ml, ms

Each electron has a different quantum number and this conforms to Pauli's rule: no electrons have the same 4 quantum numbers

  • Valence electrons

Valence electrons are electrons used in a chemical bond , and  in an atom's outermost energy level

  • Noble-gas electrons

Noble gas has a stable electron configuration of 8 valence electrons which guides the formation of chemical bonds called the octet rule

A reaction occurs when one compound reacts and is broken down into different elements or simpler compounds.
Inessa [10]

Answer:

Decomposition Reaction

Explanation:

If you are referring to what type of reaction that occurred then the answer would be decomposition reaction.

This is a chemical reaction where one reactant is broken down into two or more products.

REACTANT → PRODUCT

       AB       →      A + B

The products can be two or more elements or two or more compounds, depending on what was decomposed.
