What Type of Atom
|* Atoms are the microscopic, basic building blocks of ordinary matter.
* Atoms are composed of particles called protons, electrons and neutrons.
* The "type of atom" (and the atomic number at the top of each box in the periodic table)
"depends on the number of protons" found in its nucleus (center).
* An element is a substance that is made entirely from one type of atom. Each atom is a
building block of the element.
|"Bonding" is about...?
a) elections b) Alex Smith c) electrons d) elephants
Bond With Me
|*A molecule is formed when two or more atoms bond together.
*A covalent bond is formed when electrons are shared between atoms. An ionic bond is
formed when electrons are exchanged from one atom to the other.
*A compound is a molecule that contains at least two different elements. The molecule is
the building block of a compound, just like the atom is the building block of the element.
|Which are smallest:
a) mosquitoes b) mitochondria c) macro-molecules d) men
Which are biggest? Which are most annoying???
|* Nano means 1 divided by 1,000,000,000 (i.e. one billionth).
*Nanotechnology is about very small things - things that are too small to see – like
atoms and molecules.
*Nanokids are kids, but one billion times smaller!!

|What Type of Atom|
|Bond With Me|
|There are 90 naturally occurring types of atoms, but
scientists in labs have been able to make about 25 more!
Why do you think they are making more?
|All compounds are molecules, but not all molecules are
...I think ;-)
