Part One The Table Itself

Your guide through the periodic table.Hello comrades! I am Dmitri Mendeleev and I created the first periodic table. I will guide you through the modern day periodic table

The Creation of the Periodic TableThe Periodic Table was said to be have created Dmitri

Mendeleev in the mid-nineteenth century. He arranged the elements in order of increase of atomic mass. His table contained gaps in it. In these gaps, he predicted that elements would be found to fill in the blanks.

Did you see how I left a space between Calcium and Titanium? I knew an element would be found to fill it!

The Periodic Table TodayToday the Periodic Table is arranged in order of

increasing atomic number. This order creates a repetition

of physical and chemical

properties are

explained through periodic law.

I also noticed this repeating

pattern.

The Periodic LawAccording to the Periodic Law, if elements

are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties.

For example, all of the elements in group 7A have similar properties.

These properties determine if the element is a metal, non-metal, or metalloid.

MetalsMetals are located to the left of the periodic

stair case(the line through the table).They normally are: malleable, ductile, and

good conductors of electricity.They also have a high luster. Most metals are solid at room temperature.

The exception to this rule is Mercury,

Some examples of metals are Zinc and Titanium because they are to the left of the table. The metals are outlined in red.

Non-MetalsNon-metals are the opposites of metal and are

located to the right of the stair case. The exception is Hydrogen.

They have low luster and do not conduct electricity well.

Most are solids at room temperature, but some are gases.

Sulfur, Phosphorus, and Iodine are examples of non-metals.

Did you know non-metals are not ductile or malleable?

MetalloidsMetalloids have properties of both metals

and non-metals.Under some conditions it will act like a metal,

and under others its will act like a non-metal. An example of a metalloid is silicon. It acts as

a non-metal when it is cooled(it is brittle) and acts a metal when heated (it is malleable).

The metalloids are purple

outlined with lime green.

Part Two Groups and Periods

on the Periodic Table

How the Table is Divided The Columns of the Periodic Table are called

groups and the rows are called periods. Each element is categorized by their location

on the table and is labeled as a representative element, a noble gas, a transition metal, or an inner transition metal.

The red lines indicate groupsand the purple lines indicate periods.

That’s a novel idea!

The Representative Elements -The Representative Elements are found in Groups 1A-7A.-They are named such because they display a range of properties that represent the entire table. -The Outer Sublevel is S or P. -Examples of Representative Elements are Hydrogen, Oxygen, and Calcium.

The representative elements are outlined in red.

The Noble GasesThe Nobel Gases are found in Group 8-A of

the Periodic Table.They are also known as Inert Gases because

they rarely form bonds with other elements; this is due to their full out principal energy levels.

Their orbital configurations have full s and p

sublevels. - The

Nobel Gases are

indicated by the

green highlight.

The Transition MetalsAre located in the

middle part of the periodic table.

The elements highlighted in magenta are transition metals.

The outer sublevel of these elements are d.

Inner Transition MetalsThese elements are

removed from the table and are placed at the bottom.

Their outer sublevel is the f sublevel.

The Inner Transition Metals are highlighted

in turquoise.

Now that you Know the Table….

Let’s move on to the Trends!!!!!
