Describe the Periodic Table 0The periodic table is a chemistry reference 0It arranges all the known elements in an informative grid Describe the Periodic Table 0Elements are arranged left to right and top to bottom in order of increasing atomic number 0This order usually coincides with increasing atomic mass Describe the Periodic Table 0The Table's pattern and arrangement shows the arrangement of electrons in the atom. 0Elements have different atomic numbers - the number of protons or electrons increases up the table as electrons fill the shells. Describe the Periodic Table Elements have different atomic masses - the number of protons plus neutrons increases up the table. 0 Rows - elements of each row have the same number of energy levels (shells). 0 Columns - elements have the same number of electrons in the outermost energy level or shell (one to eight). Describe the Periodic Table 0The different rows of elements are called periods. 0 The period number of an element signifies the highest energy level an electron in that element occupies 0The different columns of elements are called groups or families 0 Elements in the same family have similar properties Describe the Periodic Table Describe How To Read The Periodic Table Describe how to read the periodic table: 0 Every table has: Describe how to read the periodic table: Atomic Number 0 The number of protons in an atom identifies the element. 0The number of protons in an atom is referred to as the atomic number of that element. Describe how to read the periodic table: Atomic Symbol: 0The atomic symbol is one or two letters chosen to represent an element ("H" for "hydrogen," etc.). 0 These symbols are used every where in the world 0 Usually, a symbol is the abbreviation of the element or the abbreviated Latin name of the element. Describe how to read the periodic table: Atomic Mass: 0The atomic mass is the average mass of an element in atomic mass units ("amu"). 0 Though individual atoms always have a whole number of amus, the atomic mass on the periodic table is shown as a decimal number because it is an average of all the isotopes of an element.
