What we do see is the atomic mass, or a weighted average the noninteger listed with an element; it is the number with several decimal places. An elemer average of the isotope masses. In other words, it is an average that takes into account the pe the weighted average, multiply each isotopic mass by its relative abundance and find the sum

Learning Goal: This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this: 35C1 In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. "Cl" is the chemical symbol for the element chlorine. A general way to show this form is: mass number Symbol atomic number It is also correct to write symbols by leaving off the atomic number, as in the following form: 35Cl or mass number Symbol This is because if you write the element symbol, such as C1, you know the atomic number is 17 from that symbol. Remember that the atomic number, or number of protons in the nucleus, is what defines the element. Thus, if 17 protons are in the nucleus, the element can only be chlorine. Sometimes you will only see 35 C1, where the atomic number is not written. Watch this video to review the format for written symbols. In the following table each column…
