In the following table each column represents a neutral atom. Fill in the gaps in the following table by working this problem out on a separate sheet of paper. You will need the periodic table in the "resources" drop down menu in the upper right hand corner of this question to look up atomic numbers and masses.

Homework Answers
Number of protons = Number of electrons in atom
Number of protons + number of neutrons = mass number
Based on these we calculate all

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: 17 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 It is also correct to write symbols by leaving off the atomic number,...

A Review Constants 1 Periodic Table Subm Previous Answers Correct When identifying isotopes of an atom, we look for atoms that have the same number of protons but different masses. This means that each isotope has a different number of neutrons. In an atomic symbol of an isotope, the upper left number represents the mass number (which consists of the sum of protons and neutrons in the nucleus of the atom) and the lower left number is...
