MS-PS 1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
DCI: Substances are made from different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms.

a unique kind of atom

The Periodic Table
To give you a better idea of where the ingredients for every living human came from, Jennifer A. Johnson, an astronomer at the Ohio State University, put together this new periodic table that breaks down all the elements according to their origin:
Periodic Table:
the chart of elements arranged in increasing order of atomic number and grouped by similar properties
Add to your VOCAB PAGE!
How many elements are there?
_________ Natural (Found in nature, alone or in combination
with other elements) Elements #1-94
_________ Synthetic (Artificially created by humans, made in a
laboratory) Elements #95-118
_________ Total # of Discovered Elements (that are confirmed)
94
118
24
A little review...
tape your copy into your notebook. Add it to your index page!
Find the zig-zag line on your periodic table!
Most of the periodic table is:
METALS (left of “staircase”)
Fewer elements are:
NON-METALS (right of “staircase”)
Even fewer elements are:
METALLOIDS (touching the “staircase”)
-have properties of both metals and non-metals

Many people have heard of Tom Lehrer's 'The Elements' song. One day I decided to search for it online to memorise some stuff about the elements and found out that Daniel 'Harry Potter' Radcliffe had recently recited it on TV. I wondered what he (and the viewers) might have learnt about the elements by listening to it but shock horror...after listening I realised the song hadn't actually told me anything about The Periodic Table, except what's on it! ��So I decided to do my own song, specifically about The Periodic Table. ��The chorus contains the first 36 elements in order up to Krypton. ��The first verse covers general info about the Periodic table.��The second verse lists the Alkali Metals and The Alkaline Earth Metals.��The third verse lists the Halogens and the Noble Gases.��Let me know if this rap helps you at all...or if it doesn't. Out of interest, if you manage to memorise the chorus, how long did it take.��good luck with your studies, or thirst for knowledge.��Peace, ��O.K

The Big Idea:
Meet the Elements & the Periodic Table:
The Periodic Table organizes the 118
different types of atoms, known as elements,
into order by their atomic number and their similar properties.
