THE PERIODIC TABLE OF ELEMENTS

• The elements on the periodic table are arranged in increasing atomic number, which shows how many protons an element has.
• The rows on the periodic table are the horizontal rows, which are periods, and there are seven of them.
• The groups on the periodic table are the vertical columns, and there are 18 of those.
• The staircase on the periodic table separates the metals and the nonmetals.
• Metals are typically shiny, good conductors of electricity, and are mainly solid-state except for mercury HG which is liquid.
• Nonmetals are not shiny, are good insulators, and have all three states of matter solid, liquid, and gas, with most being solids and gases.
• Metalloids, also known as hybrid metals and nonmetals, are found directly along the staircase on the periodic table in a forest green color.
• The lanthanides are elements 57 to 71.
• Alkaline meaning basic, these elements have a pH of greater than seven according to the pH scale.
• Transition metals are elements in groups three to group twelve, which are middle elements and metals with the exception of mercury (Hg), which is element number eighty.
• Group eighteen, also known as the noble gases, have eight full valence electrons or a full valence shell.
• Halogens are elements in group seventeen, which are very interesting as they have seven valence electrons and are found in pairs as diatomic elements, for example, fluorine (F2) is a diatomic element.
• The bottom two rows on the periodic table are the lanthanides and the actinides, which really belong in the pink and purple spots but are cut out and placed below to fit on paper better.
• The actinides are elements 89 to 1 103.
• Alkaline earth metals are a group of elements with two valence electrons which can participate in chemistry.
• Noble gases are also referred to as inert gases because they have no too little reactivity.
• Halogens are poisonous and many are gaseous.
• Alkali metals, also known as Group one metals, have one valence electron and are of interest to chemists because that's the only electron that can really participate in bonding.

• Alkaline meaning basic, alkaline earth metals have a pH of greater than seven according to the pH scale.
• The bottom two rows on the periodic table are called the lanthanides and the actinides, they belong in the pink and purple spots but are cut out and placed below to fit on a regular sized piece of paper.
• Fluorine is an example of a halogen, it is F2 because it's a diatomic element and is found in pairs.
• The actinides are the elements 89 to 1 103.
• Transition metals are elements in groups three to group twelve, they are the middle elements and they are metals with the exception of mercury HG which is element number eighty.

• Halogens are in group seventeen and are very interesting because they have seven valence electrons, most of those elements are found in pairs as their diatomic elements.
• Halogens are poisonous and many are gaseous.
