Every human being born into the world has a golden period in brain development. This period is found in the first 1-5 years of life. The period is none other than when humans are toddlers. At that time, parents are expected to be able to provide appropriate education to children to shape the personality of children from an early age. What parents ‘laced’ during the golden period in children, can affect brain development and personality when they grow up.
On this occasion we will discuss the periodic system of elements, namely the periodic table of complete chemical elements by reading the information from the periodic table itself and you will get some images of free printable periodic table of elements for kids.
Look at the periodic table starting from the top left and ending at the last line, near the bottom right. Tables are arranged from left to right based on increasing atomic numbers. The atomic number is the number of protons in an atom.
Not all rows or columns are filled. Even though there is an empty part in the middle, reading the table starts from left to right. For example, Hydrogen has an atomic number 1 and is located in the upper left. Helium has an atomic number 2 and is located in the upper right. Elements 57 to 102 are usually described as part of the bottom right of the table. These elements are “rare earths.”
Look for the “class” element in each table column. There are 18 columns. Use the term “reading class down” to read from top to bottom. Numbering is usually written above the column; however, numbering can appear at the bottom of other categories, such as metals.
The numbering used on the periodic table will be very different. Numbering can be Roman numbering (IA), Arabic numbering (1A), or numbers 1 to 18.
Hydrogen can be incorporated into the halogen family and the alkali metal family, or both.
Look for the “period” element in each table row. There are 7 periods. Use the phrase “read period to the side” to read from left to right.
Periods are usually numbered 1 to 7 on the left side of the table. Each period is greater than the previous period. This is related to increasing atomic energy levels on the periodic table.
Understand additional classification based on metals, semi-metals and non-metals. The element color will be very different.
Metals always have one color. However, hydrogen usually has the same color and is grouped with non-metals. Metals are shiny, usually solid at room temperature, delivering heat and electricity, and can be forged and elastic.
Nonmetals always have one color. Nonmetals include elements C-6 to Rn-86, including H-1 (Hydrogen). Nonmetals are not shiny, conduct heat or electricity, and cannot be forged. Nonmetals are usually gases at room temperature and can be solids, gases or liquids.
Semi metal / metalloid is usually purple or green, as a combination of the other two colors. The elements included in it form a diagonal line, extending from elements B-5 to At-85. Semi metal has several metallic properties and some nonmetallic properties. Note that elements are also sometimes written based on their families. This family includes alkali metals (1A), earth alkali metals (2A), halogens (7A), noble gases (8A), and carbon (4A). Numbering can be Roman, Arabic, or standard numbering.
