Today’s Agenda (10/3/2016): Handout Grade Reports Notes over the Periodic Table Color-Coding the Periodic Table Materials Required: Guided Notes and Periodic Table I can explain how elements are organized in the periodic table.

I can explain how elements are organized in the periodic table. The periodic table is an arrangement of elements in columns, based on a set of properties that repeat from row to row. I can explain how elements are organized in the periodic table.

I can compare early and modern periodic tables. J.W. Döbereiner published a classification system for elements and grouped elements into triads based on their chemical properties. I can compare early and modern periodic tables.

Dmitri Mendeleev arranged his periodic table of elements in order of increasing atomic mass. I can describe how Mendeleev arranged the elements in the periodic table.

Henry Moseley determined the atomic number for each known element, and arranged elements in order of increasing atomic number. I can describe the arrangement of elements in the modern periodic table.

In the modern periodic table, elements are arranged by increasing atomic number (number of protons). I can describe the arrangement of elements in the modern periodic table.

I can explain how elements are organized in the periodic table. Periodic Law states that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties. I can explain how elements are organized in the periodic table.

Periods are horizontal rows on the periodic table. I can distinguish between a group and a period on the periodic table.

I can distinguish between a group and a period on the periodic table. Groups, also known as families, are vertical columns on the periodic table. I can distinguish between a group and a period on the periodic table.

The average atomic mass is a value that depends on the distribution of an element’s isotopes in nature and the masses of those isotopes. I can explain how the atomic mass of an element is determined and how atomic mass units are defined.
