Using the Periodic Table

Transcription

1 Lesson Outline LESSON A. What is the periodic table?. The is a chart of the elements arranged into rows and columns according to their chemical and physical properties.. The table can be used to determine how all are related to one another. B. Developing a Periodic Table. In the mid-00s, Russian chemist and teacher created a table to help classify the elements by their properties. a. He placed the elements in rows of increasing atomic. b. The elements in the table showed repeating patterns; is a word used to describe such patterns. c. For example, Mendeleev noticed patterns in the of elements, the temperature at which a solid changes to a liquid.. After arranging the known elements in a periodic table, Mendeleev noticed large gaps between some elements. He predicted that scientists would find were. to fit into these spaces. Mendeleev s predictions. In the early 00s, Henry Moseley found that the problem with Mendeleev s table could be solved if the elements were arranged in rows by.. The atomic number is the number of in the nucleus of an atom of an element.. Today s Periodic Table. You can identify the properties of an element by studying its on the periodic table.. The shows the element s name, atomic number, chemical symbol, state of matter, and atomic mass.. A(n) is a column on the periodic table.. Elements in the same group have similar, which means they react with other elements in similar ways.. The rows in the periodic table are called. 0 The Periodic Table

2 Lesson Outline continued. As you read from left to right across the periodic table, atomic number by one for each element.. Most of the elements in the periodic table are, which are shiny and conduct thermal energy and electricity.. Most nonmetals are on the side of the periodic table; these elements do not conduct thermal energy and electricity.. Between the metals and nonmetals on the periodic table are the D. How Scientists Use the Periodic Table, which have properties of metals and nonmetals.. Scientists use the periodic table to predict the of the new elements they create.. Elements that are each other on the periodic table share similar properties. The Periodic Table

The periodic table is a chart that uses and to arrange elements according to their and properties.. Russian chemist developed the periodic table by organizing elements according to.. Mendeleev noticed that elements had repeating patterns, or are, with properties such as melting point,, and.. Moving from to, melting points on the periodic table first then.. fixed problems that scientists discovered with Mendeleev s table by listing elements according to increasing.. The atomic number of an element is the number of in and the nucleus of each of the element s.. Each element key on the periodic table has important information, including,,, and.. Both and properties change as you read across a period on the table.. Almost all elements in the periodic table are. 0. is/are on the left side of the periodic table, is/are on the right side, except for, and, which are between metals and nonmetals.. New metals, like Bohrium, are, or made by people.. The periodic table can be used to understand and an element s. The Periodic Table
