1. BONDING PATTERNS BETWEEN ATOMS.
2. TYPES OF MATTER IN SOLIDS.
Solids generally have their constituent particles arranged in a pattern known as crystalline structure. The crystalline structure of the solid is due to the types of matter and the chemical bonds that exist between the particles of solids. The constituent particles of a solid can be atoms, ions or molecules.
The atomic mass of a certain element is summation of the product of the decimal equivalent of the percentage abundance and the given atomic mass of each of the isotope. If we let x be the percentage abundance of the 86 amu-isotope then, the second one is 1-x such that,
x(86) + (1 - x)(90) = 87.08
The value of x from the equation is 0.73. This value is already greater than 0.5. Thus, the isotope with greatest abundance is that which is 86 amu.
The empirical formula of the compound is KClO₃.
<h3>
Empirical formula </h3>
This is the simplest structural formula a compound can have.
The given mass of the elements;
potassium, K = 5.99 g
chlorine, Cl = 5.43 g
oxygen, O = 18.77 g - (5.99 + 5.43)g = 7.35 g
The empirical formula of the compound is calculated as follows;
<em>Divide through by the smallest fraction;</em>
empirical formula = KClO₃

It is an example of a physical change because the chocolate changes from a solid to a liquid however it’s chemical composition is not changed so it’s a physical change.
