Atoms and molecules are held together at the atomic level by the electromagnetic interactions between electrons, protons, and ions. For example, an ionic compound is held together by the attraction between the positive and negative charges of its constituent ions. Two atoms forming a covalent bond are held together by the mutual attraction they have toward one or more electrons. This interaction is quantized through the concepts of electronegativity and charge.

How do the coefficients in a balanced equation compare quantites of two substances?
These coefficients show the number of molecules involved in the chemical reaction.
What is an atom or molecule called when involved in a chemical reaction?
Before the reaction, the atoms and molecules are called reagents. After the reaction, the resulting atoms and molecules are called products.As a reaction occurs, the reagents may form an activated complex and almost immediately decay into products.
Difference between 2O and 2 O in a chemical equation?
2O means two molecules of oxygen involved in the reaction and O2 means two atoms of oxygen which are ready to form a bond after a chemical reaction
Will a chemical reaction in different molecules trade positions with exchange reaction?
An exchange reaction is defined as a chemical reaction in which two different molecules or pairs of molecules exchange places. So yes, a chemical exchange reaction will result in different molecules trading positions.
Can a chemical reaction with different molecules trade positions with decomposition?
Decomposition is its own category of chemical reaction. A reaction in which different molecules trade positions is known as an exchange reaction, as pairs of molecules essentially exchange places with one another.
Reaction that break apart large molecules are involved in which type of digestion?
chemical
Is the number before a chemical formula indicates how many molecules are involved in a chemical reaction?
Yes, that is true.
What general terms does a chemical equation indicate?
Chemical formulas of reactants and products; number of molecules involved in the reaction.
Molecules involved in a chemical reaction must collide to react What is this concept called?
Collision Theroy
What is the name of a number in front of a chemical formula in an equation called?
This is the number of molecules or atoms involved in the reaction.
What are the two coefficients?
In a chemical equation, coefficients represent the no. of molecules or atoms involved in a complete chem. reaction.
How is heat involved in chemical changes?
Heat increases the speed at which the molecules move, thus increasing the speed of the reaction.
How do you identiy each chemical reaction?
You can identify each chemical reaction by naming it,
How do the coefficients in a balanced equation compare quantites of two substances?
These coefficients show the number of molecules involved in the chemical reaction.
How are reactant elements or molecules different than the compound produced in a chemical reaction?
reactant elements and molecules are used in a chemical reaction, they are not mixed or combined or produced in a chemical reaction.
What is an atom or molecule called when involved in a chemical reaction?
Before the reaction, the atoms and molecules are called reagents. After the reaction, the resulting atoms and molecules are called products.As a reaction occurs, the reagents may form an activated complex and almost immediately decay into products.
What reactants are in chemical reaction?
The elements or molecules that participate in a chemical reaction and yield a product.
