How do I write ionic formula for Sodium Aluminum Silicate? Please explain in a easy way ,,,,,,,,,,,,
There are literally thousands of different kinds of sodium aluminum silicate, and they do not have simple formulas, because the aluminum and silicon form giant oxygen bridged anions. Most clay minerals are of this type, more or less, although potassium is more common in clays than sodium. So there is no easy way. The empirical formula is sometimes written as a ratio of Na2O to Al2O3 to SiO2, but this gives no information about the structure, only the overall composition. Look up clay minerals online. Wikipedia might be a good start. Also the website mentioned in the other answer.
