Atomic structure powerpoints series#

Actually, protons and neutrons can be further split into quarks.

Atoms composed of protons, neutrons, and electrons.

In particle accelerators and in stars, subatomic particles can be found.

Greek origin – atomos which means indivisible.

Smallest particle of an element that maintains the properties of the element.

Taken with a scanning tunneling microscope at the IBM Almaden Laboratory in San Jose, CA.

Iron atoms positioned into a circular ring that “corrals” electrons.

Strings of dots are chains of thorium atoms.

Photo made in 1970 with a scanning electron microscope by researchers at the University of Chicago's Enrico Fermi Institute.

Hydrogen is most abundant element in universe.

Life – mostly oxygen, carbon, hydrogen, nitrogen, & calcium.

Greater than 99% of matter on earth is formed by about a dozen elements.

The remaining elements are made in laboratories and are too unstable (radioactive) to occur in nature in significant amounts.

Only about 118 different elements make up all the materials we know.
