How To Read The Periodic Table Of Elements

Within these blocks are identifying numbers and letters.

How to read the periodic table of elements. The number on the very top is called the atomic number and it represents the number of protons in a single atom of the element. It tells the number of protons in an element. To read the periodic table start at the top left with the elements with the lowest atomic numbers which tells you how many protons each atom has. The periodic table is a graphical collection of element data.

The atomic number itself can also tell you lots about the element. To find out how many protons neutrons and electrons are in these larger atoms you need to read the information from the periodic table of elements. Ask the child to look at one of the squares on the periodic table. Reading the periodic table the interactive model doesnt allow you to build atoms with more than 10 protons.

The periodic table has rows running left to right which are called periods and columns running up and down which are called groups. For the element helium shown above the atomic number is two. The number at the top is the atomic number. The rows periods and columns groups organize elements according to similar properties.

Neon is in the second row or period which means it has two shells. The elements are grouped together based on their similarities and because they all have the same number of electrons in their outer shell. Each element within the periodic table has its own block. It will show a number at the top two or three letters and a number at the bottom.

Then as you move right across the chart make note that the atomic weight shown at the bottom of the square also increases. Atomic numbers range from 1 to 118. There are 18 groups columns in the periodic table. It can help to understand the valency the coordination number and the position you would expect to find it on the periodic table.

Elements in the periodic table are broken out into rows based on the number of shells they have. The periodic table also known as the periodic table of elements is a tabular display of the chemical elements which are arranged by atomic number electron configuration and recurring chemical propertiesthe structure of the table shows periodic trendsthe seven rows of the table called periods generally have metals on the left and nonmetals on the right.
