Even when they combine with another substance and form a molecule, scientists expect certain characteristics to occur that distinguish that compound from another.

CIR Room 9: Metals, Non-Metals and Metalloids
http://spcpchemroom9.blogspot.com/2010/10/metals-non-metals-and-metalloids.htmlSome exceptions to these are the metals - sodium and calcium (very soft), gold and copper (yellowish colour), and mercury (low melting and boiling points). Non-metals are separated from metals by a line that cuts diagonally through the region of the periodic table containing elements with partially filled p orbitals
For example, beryllium (Be) and magnesium (Mg) are found in column two and share certain similarities while potassium (K) and calcium (Ca) from row four share different characteristics
KS3 metals and non-metals - found in the periodic table
3 - 18 48 118 1018 Where are the non-metallic elements found in the periodic table? 4 - In the middle In the top rows On the left-hand side On the right-hand side The list which contains only metals is ....... 2 - it is shiny and reactive it is shiny and unreactive it is soft and a good conductor of heat it is soft and cheap The correct way to write the symbol for the metal chromium is ......
They are also relatively dense, susceptible to corrosion, conduct electricity and heat, are ductile (can be made into wires) and malleable (can be made into sheets).

Periodic Table of Elements and Chemistry
Just as Adams and Le Verrier could be said to have discovered the planet Neptune on paper, Mendeleev could be said to have discovered germanium on paper. This quantity can only be the charge on the central positive nucleus, of the existence of which we already have definite proof." Henry Moseley, Philosophical Magazine, Vol
Periodic Table of Elements - Elements Database
Mendeleev's Periodic Table It was only in 1869 when Dmitri Mendeleev, an inventor and chemist of Russian origin, discovered the Periodic Law and organized all chemical elements in columns and rows. Origins of the Periodic Table of Elements The Periodic Table displays all known chemical elements which are grouped by chemical properties and atomic structure
Metals, Metalloids, and Non-metals - Shmoop Chemistry
It's a metalloid.Okay, what about reactivity? Do metalloids react the same way as their metallic neighbors or their non-metallic neighbors? The truth is, it depends on the element with which they are reacting. These metals are aluminum (Al), gallium (Ga), indium (In), tin (Sn), thallium (Tl), lead (Pb), and bismuth (Bi).These metals are solid, shiny, and good conductors of electricity and heat, all properties that we normally associate with metals
Periodic Table of the Elements - Metalloids
The element carbon; its diamond allotrope is non-metallic, however the graphite allotrope is electrically conductive showing characteristic more like a metalloid. This property makes metalloids useful in electronic components.Some allotropes of elements show more pronounced metal, metalloid or non-metal behaviour than others
Heat and electricity travel easily through metals, which is why it is not wise to stand next to a flagpole during a thunderstorm! Nonmetals, on the right side of the periodic table, are very different from metals
