Introduction to atoms…page 11 Attach questions to left side of the paper

Introduction to the ATOM…11 What is matter? What is an atom? What is a nucleus? What is a proton? What is a neutron? What is an electron? What is the atomic number? What is the atomic mass?

Introduction to the Atom…11 What is Matter? Anything that has mass and takes up space

The smallest particle of an element. What is an ATOM?

Atoms are so small that… It would take a stack of about 50,000 aluminum atoms to equal the thickness of a sheet of aluminum foil from your kitchen. A typical human cell contains roughly 1 trillion atoms. A speck of dust might contain 3 trillion atoms. 1 trillion atoms  .

What are atoms made of? Protons Neutrons Electrons

What is the nucleus? The center of the atom

What atom parts are found in the nucleus? Protons and Neutrons

What is a PROTON? A positively charged particle + - +

A particle that has no charge (neutral) What is a Neutron? Not the same neutron

How do you calculate neutrons? Neutrons=mass-atomic number How do you calculate neutrons?

Electron (-) A negatively charged particle

Where are electrons located? outside the nucleus + - -

What is the Atomic Number? The amount of protons in an element Every element has a different atomic number What is the Atomic Number?

How much the atom weighs Protons + Neutrons What is ATOMIC MASS? How much the atom weighs Protons + Neutrons
