This week we have done much with the elements and the periodic table. We are learning about the elements atomic mass, isotopes, protons, nuetrons, electrons and even thier symbols. We have learned about families and groups of elements. How their characteristics differ from different parts of the period table. We also practiced reading the number of protons and electrons and finding the neutrons from that.

Elements and atoms
This week in chemistry class we have learned much about Elements and atoms. Today we answered questions about elements and their information on the periodic table. Also we found out about thier characteristics and reactivity they give. These elements seem very interesting and I cant wait to learn more about them.
