Unit 11 – ELEMENTS notes
A. Unit 11 Elements
1. Lesson 1: What is matter? (pgs. 214-215)
a. Vocabulary (Science Words)
1) matter – anything that has mass and takes up space
2) volume – the amount of space matter takes up
3) chemistry – the study of matter
b. Main Ideas (What You Learned)
1) Matter is anything that has mass and volume.
2) Nearly everything you see in the world is made of matter.
3) Chemistry is the study of matter.
2. Lesson 2: In what forms is matter found? (pgs. 216-217)
a. Vocabulary
1) phase – one of the forms in which matter may be found
2) solid – the form of matter that has a definite shape and volume
3) liquid – the form of matter that has a definite volume but no definite
shape
4) gas – the form of matter that has no definite shape and no definite
volume
5) molecules – the tiny bits that make up matter
6) vibrate – move back and forth quickly in a small place
b. Main Ideas
1) There are three phases of matter: solids, liquids, and gases.
2) The molecules in a solid cannot change position. They can only
vibrate in place.
3) The molecules in a liquid can slide past each other and change
position.
4) The molecules in a gas are far apart. They can easily spread out to
all parts of a container.
3. Lesson 3: Can matter change its form? (pgs. 218-219)
a. Vocabulary
1) freezing – changing from a liquid to a solid
2) melting – changing from a solid to a liquid
3) evaporation – changing from a liquid to a gas
4) condensation – changing from a gas to a liquid
b. Main Ideas
1) Liquids may change to solids by losing heat.
2) Solids may change to liquids by gaining heat.
4. Lesson 4: What are the simplest forms of matter? (pgs. 220-221)
a. Vocabulary
1) element – a simple substance that cannot be broken down into
simpler substances
b. Main Ideas
1) All substances are composed of elements.
2) There are more than 110 elements.
5. Lesson 5: What are metals and non-metals? (pgs. 222-223)
a. Vocabulary
1) identify – recognize or find out what something is
2) properties – things that help identify something
3) luster – the shininess of a material
4) malleable – able to be hammered into different shapes
b. Main Ideas
1) Metals can be identified by their properties.
a. Metals are solids at room temperature (except mercury).
b. Metals have a silver-gray color (except gold and copper).
c. Metals have a shiny luster.
d. Metals are malleable.
e. Metals are good conductors of electricity and heat.
2) Elements that are not metals are called non-metals.
3) Metals and non-metals generally have opposite properties.
6. Lesson 6: What are chemical symbols? (pgs. 224-225)
a. Vocabulary
1) chemical symbols – a short way of writing the names of the elements
2) universal – worldwide; the same all over the world
b. Main Ideas
1) Chemists use symbols for the names of the elements.
2) The symbols for the elements are universal.
3) Chemical symbols always contain 1 or 2 letters. The 1st letter is
always capitalized and the 2nd letter is always lower case.
7. Lesson 7: What does the periodic table tell about the elements? (pgs.
228-229)
a. Vocabulary
1) atomic number – a number used to identify an element and show
its place in the periodic table. The atomic number is equal to the number of
protons in an atom.
2) group – a family of elements going down the periodic table
3) period – a family of elements going across the periodic table
b. Main Ideas
1) The periodic table is a chart showing the elements in order of
atomic number,
2) Metals are on the left side of the side of the chart, and non-metals
are on the right side.
3) Elements are arranged in groups and periods in the table.
