To write chemical formulas correctly, you can follow these easy steps:
Know the Elements: First, find out which elements you are working with. Use their symbols from the periodic table. For example, sodium is written as Na and chlorine is written as Cl.
Find the Ratio: Look at the valency of the elements to figure out their simplest ratio. For example, sodium (Na) has a valency of +1, and chlorine (Cl) has a valency of -1. So, when you put them together, the formula for sodium chloride is NaCl.
Understand Different Formulas: It's important to know the difference between two types of formulas. The empirical formula shows the simplest ratio of elements. The molecular formula shows the actual number of atoms. For example, for glucose, the empirical formula is CH, but the molecular formula is C₆H₁₂O₆.
The more you practice with different compounds, the better you will get at writing chemical formulas!
