How do you count atoms in a chemical formula?
To count atoms, look at each element symbol and the subscript number after it, which tells how many atoms of that element are present. Multiply atoms inside parentheses by the subscript outside, and apply a coefficient in front to every atom in the formula. Add the totals for each element.
What is the difference between subscripts and coefficients when counting atoms?
A subscript is the small number after an element that counts atoms of that element within one molecule, such as the 2 in H2O. A coefficient is the large number in front of a formula that multiplies every atom in it. Both must be considered to count atoms accurately.
Why is counting atoms important for balancing chemical equations?
Counting atoms is essential because the law of conservation of mass requires the same number of each element on both sides of an equation. By counting atoms, students adjust coefficients until each element balances, ensuring no atoms are created or destroyed and the chemical equation correctly represents the reaction.
