Metals makeup more than 75% of the elements in the Periodic Table. Metals are characterized by the following physical properties.
1. They have metallic shine or luster.There are 17 nonmetals in the periodic table, and they are characterized by four major physical properties.
1. They rarely have metallic luster.The six metalloids are B, Si, Ge, As, Sb, and Te. The properties of the metalloids have characteristics in between that of the metals and the nonmetals. They are good conductors of heat and electricity, but they are not good conductors or insulators.
Periodic PropertiesThe periodic table also has certain properties characteristic of certain regions in the periodic table.
Alkali MetalsThese are the metals in the first column of the periodic table. They are soft shiny metals that usually combine with group VIIA nonmetals in chemical compounds in a 1:1 ratio.
Alkaline Earth MetalsThese are the elements in the second column of the periodic table, and they are very similar to the alkali metals. They combine with the group VIIA nonmetals in a 1:2 ratio.
HalogensThe halogens are found in group VIIA. They are fluorine, chlorine, bromine, and iodine. The halogens exist as diatomic molecules in nature.
Noble GasesThe noble gases are also called rare gas elements, and they all occur in nature as gases. The noble gases make up the group VIIIA which is the last column in the periodic table. The noble gases fulfill the octet rule by having a full outer level with 8 valence electrons. Therefore, they do not undergo chemical reactions because they do not accept any electrons.
Transition MetalsThe transition metals are the metals located between columns IIA and IIIA in the periodic table. The elements also have valence electrons in two shells instead of one.
good conductors of electricity
good conductors of heat
maeleable
high tensile strength
metals are dense, ductile, have a metallic luster, they generally take up the left 4/5 of the periodic table, usually are good conductors of heat and electricity
Elements with properties of Metals and Non-metals are shown in the periodic table in the "stairs" which is the pattern seen on the right hand side of the periodic table consisting of the elements, Boron; Silicon; Germanium; Arsenic; Antimony; Tellurium; and Pollonium, that is according to the modern day periodic table. These elements are known as metalloids. Richard hope tht helps :D x
Periodic means reoccuring. On the periodic table, periodic refers to the elements in each group having some of the same simularities and some of the same properties.
Around 80 percent of the elements on the Periodic Table are metals. Some of the metals are tin, aluminum, francium, lead, and magnesium.
Most metals are denoted in the Periodic Table by the suffix -ium. Some metals are Cadmium, Sodium and Iron.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
Group 17 (the halogens) are all highly reactive non-metals.
Metalloids are the border lines between the metals and the nonmetals in the Periodic Table.
alkali metals, alkali earth metals, and some transition metals.. that is on the left side if you divide the periodic table in two.
On some periodic tables metals have a different color.

metals on left, non-metals on right, some others in middle.
Periodic means reoccuring. On the periodic table, periodic refers to the elements in each group having some of the same simularities and some of the same properties.
Some share the same amount of valence electrons. Some could be classified in the same group such as metals, Nonmetal, Metalloids.
No. Noble gases, halogens, and nonmetals are on the right side of the periodic table. Metals including, alkali metals, alkaline earth metals, and transition metals are all located on the left/center.
No. The majority of the columns on the periodic table, 26 of them, contain only metals. An additional 4 contain some metals along with nonmetals and/or metalloids.
Elements with similar properties are usually located in the same Group (column) on the Periodic Table.
