  • Counting Atoms The formula for a compound indicates the elements that make up the compound and the number of atoms of each element present in the compound. These numbers of atoms are indicated by the use of small numbers called subscripts. Sometimes groups of atoms act as a single atom. Such a group of atoms is called a polyatomic ion.

  • Oct 08, 1999 · You can count the number of atoms of each element in a chemical formula by multiplying the coefficient by the subscript, recognizing that those coefficients and subscripts that are not shown are equal to 1. For example, if we write 2NH 3 (which is 2N 1 H 3) we calculate the number of atoms as follows: For N we have 2 x 1 = 2 For H we have 2 x 3 = 6

Most carbon atoms contain 6 neutrons, but some may contain more or less than 6. Each atom of hydrogen is guaranteed to contain 1 proton. Unless the atom is electrically charged, it will contain 1 electron as well to balance the charge of the one proton. Most hydrogen atoms contain no neutrons, but some contain either one or two neutrons.
