1.

Acid

  • An acid is a substance that tastes sour, reacts with
  • Metals and carbonates.
2.

ATOM

  • An atom is the smallest unit that makes up matter
  • And has the characteristics of an element. Atoms are made
  • Up of protons, neutrins, and electrons.
3.

ATOMIC MASS

  • The atomic mass is the number of protons and neutrons
  • In the nucleus of an atoms.
4.

ATOMIC NUMBER

  • The atomic number is the number of protons
  • In the nucleus and also reflects the number of elcectrons
  • In a neutral atom.
5.

BASE

  • A base is a substance that tasts bitter, and feels
  • Slippery.
6.

BOILING POINT

  • The boiling point is the temperature
  • At which a substance changes from the liquid
  • Phase to the gas phase.
7.

CELSIUS SCALE

  • The celsius scale is the metric temperature
  • Scale on which water freezes at 0C and boils at 100C
8.

CHEMICAL CHANGE

  • A chemical change or reactions takes place
  • On the atomic level and produces a new substance.
9.

CHEMICAL PROPERTY

  • A chemical property is a characteristic of a substance
  • That is observed when it undergoes a chemical change.
10.

COMPOUNDS

  • Compounds are made up of different kinds of
  • Elements;the elements that make up the compound
  • Form a new substance with different properties.
11.

CONDUCTIVITY

  • Conductivity refers to the ability to elements
  • To transmit heat or electricity.
12.

CONSERVATION OF MATTER

  • The law of conversation of matter states
  • That matter cannot be created or destroyed
  • In a chemical change.
13.

DENSITY

  • Density is the amount of mass of a substance
  • In a specific volume, calculated by
  • Mass divided by volume.
14.

DUCTILE

  • Ductile is then physical property of metals
  • That are capable of being drawn out
  • Or hammered into a thin wire or strip
15.

ELEMENTS

  • Elements are substances that are made up
  • Of only only kind of atom.
16.

FAHRENHEIT SCALE

  • The fahrenheit scale is the scale in which
  • The temperature differences between the melting
  • And boiling points of water is divided into 180
  • Equal intervals called degress.
17.

MALEABILITY

  • Malleability is the physical property's
  • Of metals that are capable of being bent,
  • Extended or shaped through force, such as
  • Pressure and beating with a hammer or
  • Roller.
18.

MASS

  • Mass is e amount of matter (stuff) within a substance
  • Or an object.
19.

MELTING POINT/FREEZING POINT

  • The melting point is the temperature at which
  • A substance changes from the solid phase
  • To the liquid phase.
20.

MIXTURES

  • Mixtures are made up of substances that remain the same
  • Substance;mixtures can be separated into their individual parts
  • And keep their original properties.
21.

OXIDATION

  • Oxidation is the interaction between oxygen molecules
  • And the different substances they come in contact with,
  • Included anything from metals to living tissue.
22.

PHYSICAL CHANGE

  • A physical change is a change that changes
  • The size or shape of a substance, but the
  • Physical properties and substances remain the same.
23.

PHYSICAL PROPERTIES

  • Physical properties are attributes of a substance that can be
  • Observed or measured that helps to define or identify
  • The substance.
24.

PRODUCTS

  • Products are the new substance or substances formed in a
  • Chemical reaction.
25.

REACTANTS

  • Reactants are the starting substance or substances in a
  • Chemical reaction.
26.

SOLUBILITY

  • Solubility is the ability of a substance to dissolve in water.
  • Solubility is a characteristic property of substances.
27.

TEMPERTURE

  • Temperature is a measure or the average kinetic
  • Energy of molecules.
28.

VOLUME

  • Volume is the amount of space taken up by
  • A substance or an object, regardless
  • Or its shape, volume is measured in units of milliter
  • (ML) and liter (L).
