Periodic Table Worksheet: Worksheet On The Periodic Table With Answers
The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties. It is generally accepted that the modern periodic table was first published by Dmitri Mendeleev in 1869, although several other scientists had developed similar tables prior to this.The
periodic table is a powerful tool for understanding the behavior of elements and their compounds. It can be used to predict the properties of new elements, to design new materials, and to understand the chemical reactions that occur in the world around us.
Table Structure and Design
The periodic table is a rectangular table with 18 vertical columns, called groups, and 7 horizontal rows, called periods. The groups are numbered 1-18 from left to right, and the periods are numbered 1-7 from top to bottom.The first two columns of the periodic table contain the element symbol and the element name.
The element symbol is a one- or two-letter abbreviation for the element’s name. The element name is the full name of the element, written in both uppercase and lowercase letters.The third and fourth columns of the periodic table contain the atomic number and the atomic mass of the element.
The atomic number is the number of protons in the nucleus of an atom of the element. The atomic mass is the weighted average mass of all the isotopes of the element.
Element Information
The periodic table can be used to find a wealth of information about the elements. For example, you can use the periodic table to find the:
- Element symbol
- Element name
- Atomic number
- Atomic mass
- Electron configuration
- Oxidation states
- Physical properties
- Chemical properties
The periodic table is an essential tool for any student of chemistry. It is a valuable resource for learning about the elements and their properties.
Table Customization
The periodic table can be customized to meet your specific needs. For example, you can:
- Add or remove columns and rows
- Change the order of the elements
- Change the colors of the table
- Add images or other graphics
You can also find a variety of pre-made periodic tables online. These tables can be downloaded and printed for free.
