THE PERIODIC TABLE AND HOW IT RELATES TO CHEMISTRY

BY:

FROM ITS ORIGINS SOME 200 YEARS AGO, THE PERIODIC TABLE HAS BECOME A VITAL TOOL FOR MODERN CHEMISTS

DMITRI MENDELEEV FORMED THE PERIODIC TABLE IN FEBURARY OF 1869

DMITRI MENDELEEV

DMITRI MENDELEEV WAS BORN IN RUSSIA IN 1834. HE IS BEST KNOWN FOR HIS DISCOVERY ON THE PERIODIC LAW (1869). HE DIED IN 1907.

WHILE WRITING A BOOK ON THE ELEMENTS, MENDELEEV BEGAN TO WONDER HOW HE COULD GROUP THE ELEMENTS. THEN HE STARTED MOVING AROUND THE ELEMENTS, WHICH EVENTUALLY LED TO THE FIRST VERSION OF THE PERIODIC TABLE

A TABLE OF THE CHEMICAL ELEMENTS ARRANGED IN ORDER OF ATOMIC NUMBER. THE ELEMENTS ARE ARRANGED IN GROUPS OF SIMILAR CHEMICAL PROPERTIES. 

AN ATOM IS THE BASIC UNIT OF A CHEMICAL ELEMENT

THE PERIODIC TABLE IS MADE UP OF ELEMENTS, WHICH ARE ALL MADE UP OF ATOMS

ELEMENTS ALL HAVE AN ATOMIC NUMBER, WHICH IS FOUND AT THE TOP OF THE ELEMENT

THE SYMBOL OF THE ELEMENT IS IN THE MIDDLE, THIS INDICATE WHICH ELEMENT YOU ARE LOOKING AT

ELEMENTS ALL HAVE AN ATOMIC MASS, WHICH IS FOUND AT THE BOTTOM OF THE ELEMENT

EVERY ELEMENT HAS A UNIQUE ATOMIC MASS AND NUMBER. ATOMIC NUMBR INDICATES THE NUMBER OF PROTONS IN THE ATOM OF THE ELEMENT. THE ATOMIC MASS IS THE SUM OF THE PROTONS AND NEUTRONS IN THE ATOM.

THE PERIODIC TABLE HELPS US TO UNDERSTAND CHEMISTRY BECAUSE WE CAN USE IT TO LEARN MORE ABOUT ELEMENTS AND THE ATOMS THAT MAKE THE ELEMENTS UP.

THE PERIODIC TABLE IS THE MOST IMPORTANT CHEMISTRY REFERENCE THERE IS

THE PERIODIC TABLE ARRANGES ALL THE ELEMENTS IN AN ORGANIZED AND INFORMATIVE MANNER

THE PERIODIC TABLE HELPS CHEMISTS TODAY BECAUSE IT ALLOWS THEM TO EASILY ACCESS INFORMATION ABOUT THE ELEMENTS 

ONE WAY IS SIMPLY READING THE NUMBERS OFF THE TABLE

ANOTHER WAY IS THEY CAN SEE ATOMIC AND CHEMICAL TRENDS BY SEEING WHERE DIFFERENT ELEMENTS ARE PLACED ON THE TABLE
