What’s Inside?

Materials:• Sealed box with object inside• Science Notebook• Pencil or pen

Procedure:1. DO NOT OPEN THE BOX. The box will remain sealed throughout

this lesson.2. Use your senses to gather information about the object in the

box.3. Write your observations on the piece of paper.

You need to write 6 observations on a piece of notebook paper titled “ What’s Inside”

4. Analyze your observations. Form a conclusion about the object’s shape and size.Write a brief conclusion “I think what is inside the box is (shape), (size), (density), (property 1) and (property 2).”

5. On the paper, draw the box and what you think the object inside looks like.

You have 15 minutes

Without the option of

opening the box, what tools might make the identification of what is in the box easier?

What clues did you use to determine what is inside?

How large is an atom?

0.00000002 cm ( two hundred millionths of a cm) is the size of an atom

Paper Cutting Activity

Cut the paper in half as many times as you

can.

Keep the trash in the lid

COUNT how many time your cut and record that number on the half sheet of paper


How many time did you cut the paper in half?

Did anyone cut a piece of paper down to the size of one atom?

Can we actually cut the paper until we arrive at the size of an atom? Why?

Then how have scientist developed their ideas about atoms? Based on observation (indirect evidence) of the behavior

of matter


LISTEN to the PowerPoint as I read

Record the correct answer in the blank

Notes

460 BC - Greek philosopher proposes the

existence of the atom

His theory: all atoms are small hard particles made of a single material formed into different

shapes and sizes always moving, and that they form different

materials by joining together

Democritus

John Dalton

1803 - British chemist; elements combined in

specific proportions to form compounds. His theory:

all substances are made of atoms that cannot be created, divided, or destroyed

atoms join with other atoms to make new substances atoms of the same element are exactly alike, and

atoms of different elements are different in mass and size (elements)

John Dalton

1852 - English chemist developed the valence

theory

His theory: every atom has a fixed number of bonds (chemical every atom has a fixed number of bonds (chemical

links) that it can formlinks) that it can form for the atom to be stable, all of these bonds must for the atom to be stable, all of these bonds must

be used.be used.

Edward Frankland

J.J. Thomson

1897 - English chemist and physicist discovered

1st subatomic particles

His theory: negatively charged particles called electrons and

positively charged matter created a model to describe the atom as a sphere

filled with positive matter with negative particles mixed in

Referred to it as the plum pudding model

J.J. Thomson

Ernest Rutherford

1912 - New Zealand physicist discovered the

nucleus

His theory: small, dense, positively charged particle present in

nucleus called a proton electrons travel around the nucleus, but their exact

places cannot be described

Ernest Rutherford

Niels Bohr

1913 - Danish physicist discovered energy levels

His theory: electrons travel around the nucleus in definite

paths and fixed distances electrons can jump from one level to a path in

another level

Niels Bohr

Erwin Shrodinger

1924 - Austrian physicist developed the electron

cloud model

His theory: electrons exact path cannot be predicted regions, referred to as the electron cloud, are areas

where electrons can likely be found.

Erwin Shrodinger

1932 - English physicist discovered neutrons

His theory: neutrons have no electrical charge neutrons have a mass nearly equal to the mass

of a proton unit of measurement for subatomic particles is

the atomic mass unit (amu)

What Is an Atom?

Atoms are often referred to as the building blocks of matter.

Each element on the periodic table is composed of one type of atom and cannot be broken down into a simpler substance.

What Is an Atom?

Atoms are composed of smaller subatomic particles such as the proton, neutron, and electron.

Atoms contain a nucleus surrounded by an electron cloud that consists of one or more energy levels.

Protons are positiveNeutron are neutralElectrons are negative

Inner Structure of an Atom

• Nucleus - Small, dense, positively charged center of the atom which contains most of the atom’s mass

Inner Structure of an Atom

• The nucleus contains the following subatomic particles:

Protons - positively (+) charged particles

Neutrons - particles that have no charge (neutral), but contribute to the atom’s mass

Outer Structure of an Atom

• Electron cloud - an area

• around the nucleus where

• electrons are likely to be found orbiting the nucleus in several energy levels


• The electron cloud contains several energy levels

Electrons - negatively (-) charged particles located in specific energy levels surrounding the nucleus

Warm Up

What are protons? Where are they located? What is their mass? Positively charged particles that determine the

identity of an element; in the nucleus; 1 amu

What are electrons? Where are they located? What is their mass? Negatively charged particles in the electron cloud;

very small mass less than 1 amu (~1/2000)

What are neutrons? Where are they located? What is their mass? Neutrally charged (no charge) particles in the

nucleus; mass of 1 amu

It’s OK if you don’t know the

mass


• Multiple energy levels in the electron cloud completely surround the nucleus. Electrons follow a specific order to fill the energy levels.

Maximum of 2

electrons

Nucleus

Maximum of 8

electrons Maximum of 8

electrons*

*Applies to the first 18 elements only


• The electrons in the outermost energy level are called valence electrons

• We will go into more detail about the importance of valence electrons in our next unit.

Questions

What are valence electrons? Electrons in the outermost level

Each energy level can hold a specific number of electrons. For example, the 1st energy level (the level closet to the nucleus) can hold two electrons. The 2nd energy level can hold eight electrons, and the 3rd energy level can hold eight electrons.

Atom Characteristics

The number of protons in the nucleus is the atomic number of that atom. Protons are used to identify elements.

The atomic number represents the number of protons (+) and is equal to the number of electrons (-).

Atom Characteristics

The atomic mass is the mass of the protons plus the mass of the neutrons.

Atomic mass is recorded in the SI units: atomic mass units (amu).

Protons and neutrons each are given an amu of 1.

Electrons have a mass of nearly zero.
