What are valence electrons and what do they do?

They determine how great is the valence of a chemical element; they are the electrons involved in the formation of a chemical bond.


Valence electrons are involved in what?

Valence electrons are involved in forming chemical bonds between atoms, which determines the reactivity and behavior of elements in chemical reactions. These electrons are located in the outermost energy level of an atom and are responsible for determining the element's position in the periodic table and its properties.


Do the elements involved in a chemical reaction stay the same?

No. Each reaction will generally have different elements.


What is involved in acid formation?

Chemical change happens when there is an acid formation as the substances and chemicals reacts to form new substances.


Is the enthalpy of formation always negative?

No, the enthalpy of formation can be positive, negative, or zero, depending on the specific chemical reaction and the substances involved.


What is the relationship between the heat of reaction and the heat of formation in a chemical reaction?

The heat of reaction is the difference between the heat of formation of products and reactants in a chemical reaction. It represents the amount of heat released or absorbed during the reaction. The heat of formation is the heat change when one mole of a compound is formed from its elements in their standard states. The relationship between the two is that the heat of reaction is related to the heat of formation of the substances involved in the reaction.


Is the inner electrons involved in chemical changes?

No, inner electrons are not typically involved in chemical changes. They are tightly bound to the nucleus and do not participate in the bonding or interactions that drive chemical reactions. It is mainly the outer electrons, or valence electrons, that are involved in chemical changes.


What is rusting and what elements and compounds are involved?

Rusting means the oxidation of iron. The chemical formula of rust is Fe2O3. Elements Fe and O are involved.


When substances chemically combine what do they do?

A chemical reaction occur: the transfer of electrons between elements is involved.


What is it called if two or more elements are involved in a chemical reaction?

What role do valance electrons playing the formation of compounds and elements?

The valence electrons are the only electrons involved in chemical bonding. In covalent bonding sharing occurs In ionic bonding electrons are tranferrred In metallic bonding they are deloclaised across the lattice
