Atoms MacArthur MS Curriculum

2 EPISD Standards Based Curriculum 2012-2013
Warm Up In your Interactive Student Notebook draw an atom and label it’s parts. You have 1 minute think time You have 2 minutes draw time How did you do? Watch the video and compare it to your drawing. EPISD Standards Based Curriculum

3 The term matter describes all of the physical substances around us
Matter is anything that has mass and takes up space The Universe is made up of matter and energy

4 Matter is made up of atoms
*Matter is made up of atoms. *An atom is the smallest whole particle of matter. * The atom is made of three smaller Sub-Atomic particles: Protons, Neutrons, and Electrons.

5 Early Models of the Atom “Bohr Model”
Electrons move in definite orbits around the nucleus

6 Modern Model of the Atom: “The Electron Cloud”
Spherical cloud of varying density where an electron is more or less likely to be

7 Atomic Structure Nucleus contains: Electron Cloud contains: -Neutrons
-Protons -Electrons

8 Graphic Organizer

9 Sub-atomic Particle Protons = p+ Located in the nucleus of the atom
Have a positive charge (+) Mass = 1 amu

10 Sub-atomic Particle Neutrons = n0 Located in the nucleus of the atom
Are Neutral (Have no charge) Mass = 1 amu

11 Sub-atomic Particle Electrons = e-
Located in the electron cloud around the outside of the nucleus Have a negative charge (-) Mass = 1/1840 amu Smallest sub-atomic particle

12 Watch this video for review

13 Atomic Vocabulary Review
Atom- The smallest piece of a substance Nucleus – The center of an atom Protons- Subatomic particle found in the nucleus. It has a positive charge Neutrons- Subatomic particle found in the nucleus. It has no charge. Neutral. Electrons - Subatomic particle found in the an area called Energy levels. This is also known as “The Electron Cloud.” Negative charge. The # of protons is the same as the # of electrons. The mass of a proton & neutron is 1 amu. The mass of an electron is almost zero.

14 Atomic Structure Who am I? Who am I? Who am I?

15 Describing Atoms Atomic Number = number of protons (# p+)
Tell us the identity of the element. Atomic number is kind of like your student ID number. # protons+ or # electrons- Mass Number = #p+ + #n0 the number of protons + the number of neutrons Atomic Mass = mass of protons+ + mass of neutrons0 in the nucleus

16 Created by G.Baker
Periodic Table Atomic Number: Number of protons Also # of electrons 8 Element’s Symbol: An abbreviation for the element. O Oxygen Elements Name Atomic Mass/Weight: Weight of protons + neutrons. 16 Created by G.Baker
