Matter of the day: Physical change versus Chemical Change

Formula:


What is it?:

Physical change- melting, boiling, reshaping.

Chemical change- atoms/molecules split up and change the way they’re put together.

_____________________________________________________________

Vocabulary:

(matter: anything stuff (has mass) that takes up space (volume).)

(substance: a type of matter.*mass: how much matter there is.)

atom-smallest matter with chemical properties

sub-atomic particle: parts that make up an atom

nucleus-the center of an atom

*proton: positive particle of an atom

  • atomic number= number of protons

*neutron: no charge particle of an atom

  • atomic mass = protons + neutrons

electron cloud-area around the nucleus where electrons are

*electron: negative particle of an atom: moves fast, can be found anywhere in the electron cloud

element: one of over 100 types of atoms:

  • each classified by the number of protons
  • each reacts differently to form different substances

Essentials:

16.A pure substance is stuff made of only one kind of matter with definite properties.(i.e. sugar, salt, iron, & copper.)
17.Three states of matter are: SolidLiquid, and GasMatter will change from one state to another if thermal energy is absorbed or released. (i.e. heat solid ice and itbecomes liquid water.)
18.Some pure substances, called elements, cannot be broken down into othersubstances by any chemical means. (i.e. iron, copper, gold, carbon, & chlorine.)
19.An atom is the smallest particle of a substance (matter.)
20.The nucleus in the center of the atom made of protonsneutrons.
21.Protons are tiny positively charged particles.
22.Electrons are tiny negatively charged particles that are found in orbit around thenucleus.
23.A molecule is a group of atoms that are joined together and act as a single unit.(i.e. a water molecule is made of 2 hydrogen atoms tied to 1 oxygen atom: H2O.)
24.Physical changes change the form of a substance, but not its identity. (i.e. ice issolid water, a crushed can is still a can.)
25.In chemical changes one or more substances combine or break apart to formnew substances. (i.e. burned wood becomes charcoal and carbon dioxide gas.)
26.Volume is the amount of space that matter occupies. (i.e. a 2-Liter bottle of soda)
27.A solid has a definite volume and a definite shape. (i.e. spilled rocks look the sameas in a glass.)
28.A liquid has no definite shape of its own, but has a definite volume. (i.e. watertakes the form of the bottle it’s in and spreads out when spilled.)

30.A Gas has no definite shape of its own and can change volume easily. (i.e. askunk’s spray on a dog fills a room quickly.)
31.The elements can be arranged by similarities in the Periodic Table of the Elements. Elements in the same column react similarly. Elements in the same rowhave similar electron levels.

Matter of the day: Boiling/Melting Points

Formula:      


What is it?: Every substance has a specific temperature where its bond strength breaks down.

Why does it matter? Every substance can be identified by boiling and melting points.
