Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements.
In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity.
Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions.
Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions.
Hope this helps!

What changes are always involved in chemical reactions?
electrons are always involved in chemical reactions. how they are positioned which atom they are located if they are sharing paired unpaired etc.
Which of an electrons are involved in chemical reactions?
They have a negative charged. They are found in the electron cloud in an atom.
What do you know about types of atoms before and after a reaction?
Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.
What parts of a magnesium atom interact with other atoms during chemical reactions?
Some or all of its valence electrons.
Why is ionization energy important when discussing metal behavior in a chemical reaction?
Because it jumps from atoms to make a neutral atom which is pretty much why we have chemical reactions.
What of an atom's electrons are involved in chemical reactions?
The electrons farthest from the nucleus of the atom
What determine the atom chemical properties?
Chemical reactions depends on the valence electrons.
What is the smallest unit of matter that can enter chemical reactions and is nondivisible by chemical means?
An atom.
Which of an atoms are involved in chemical reactions?
The Electrons farthest from the nucleus of the atom
what parts of the atom that are involved in chemical reactions are the?
I figured it out electrons XD
What part of the atom is involved in the chemical reactions?
The electrons
What are valence shell electrons?
Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.
Is an atom a piece of an element?
atom - smallest piece of an element that keeps its chemical properties; compound - substance that can be broken into elements by chemical reactions
What changes are always involved in chemical reactions?
electrons are always involved in chemical reactions. how they are positioned which atom they are located if they are sharing paired unpaired etc.
What is nickel atom used for?
Nickel is used as a catalyst in many chemical reactions.
What are valence shells?
Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.
In chemical reactions The number of each kind of atom in the reactants?
Stays the same as in the products
