Chemical Formula and Equation Tool

Steps to Write a Formula:

1. Identify the elements involved (e.g., Hydrogen, Oxygen).
2. Write the symbols for each element (H, O).
3. Find the valency of each element or radical. (e.g., H = 1, O = 2)
4. Use the crisscross method to determine the subscript for each element. The valency of one element becomes the subscript for the other.
5. For radicals (polyatomic ions), use brackets if their valency is greater than 1 (e.g., SO₄²⁻ becomes (SO₄)₂).
6. For multiple atoms of the same element, use a subscript after the element symbol (e.g., H₂O for 2 Hydrogen atoms and 1 Oxygen atom).

Example: Sodium (Na) has a valency of 1 and Chlorine (Cl) has a valency of 1. Using the crisscross method, the formula becomes NaCl.

Formula Practice: Enter the valency of each element or ion and apply the crisscross method to write the formula.
