Lab 2-2: Bag of Ions and Periodic Table Chem Crunch

The periodic table is cleverly arranged to make finding and your elements easy. The biggest categories of elements are separated into periods and groups.Within the period in groups the organization sorts elements by number of valance electrons, mass number, number of shells each element has and increasing electron configuration.

1. Ions and atoms have the same number of protons and neutrons.

2. The difference of atoms and ions of the same element are the electron configuration and number of valence electrons.

3. Ions form from atoms gaining or loosing electrons to create a stable octet of 8 electrons.

4. You can determine whether the atom will gain or loose electrons from its position on the periodic table.If the atom is on the right side of the table a metal has a positive charge explaining its electric conductivity is lose an electron. On the left side of the table the non- metals are gain electrons and the metalloids gain or lose electrons. This all creates an outer shell of 8 electrons a stable octet.
