Metals,Non-metals and Metalloids
The parts of the Periodic Table of Elements
What is the Periodic Table of Elements?
The Periodic Table of Elements is an arrangement of chemical elements. The periodic table has a special name for its vertical columns. Each column has a group. The element in each group have the same number of electrons in here outer orbital.The periodic table of the chemical elements displays the organizing principles of matter.
Why is i important?!?!
The periodic table is the most important chemistry reference there is! It arranges all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.The modern periodic table has changed since Mendeleev's original table, yet both the first tables and the modern table are important for the same reason: The periodic table organizes elements according to similar properties so you can tell the characteristics of an element just by looking at its position on the table.
About metals, non-metals and metalliods
Metals
A solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
Physical Properties of Metals:
- Luster (shininess)
- Malleable (most metals can be hammered into thin sheets)
- High density (lots of mass in relationship to volume)
- Ductile ( most metals can be drawn out into thin wires)
Non-metals
An element or substance that is not a metal.
Physical properties of Non-metals:
- No luster ( dull appearance)
- Brittle ( breaks easily)
- Low melting point
Metalloids
An element whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors.
Physical Properties of Metalloids:
- Solids
- Can be shiny or dull
- Conduct heat and electricity better then non-metals but not as well as metals
