Did you know the periodic table contains many elements that are similar and totally different?
Really? Tell me more!
This is what the periodic table looks like. Each individual element contains the atomic number, symbol, element name, and atomic mass.
The periodic table is organized by periods (left/right) and groups (up/down).
Elements in the same period have the same number of energy levels. For example, the circle around this carbon atom are called energy levels. Carbon has 2 energy levels and is located in period 2.
Another fact is that the atomic # determines the number of protons and electrons!
In the periodic table, there is a zigzag line on the right hand side that divides the metals, metalloids, and nonmetals.
What are those?
-located on the left of the zig zag line -mallueable -ductile -good conductors -shiny/metallic luster -mostly solid but mercury
-both metal and nonmetal -next to zigzag line
These are metals, nonmetals, and metalloids!
-Located on right side -brittle -poor conductors -dull luster no one common state of matter
The last fact is that there are actually different groups! Group 1= Alkaline metals (highly reactive except hydrgen) Group 2= Alkaline earth metals Group 3-12=transition metals Group 17= Halogens (most reactive) Group 18- noble gases (rarely reactive except helium)
