FTCE MIDDLE GRADES GENERAL SCIENCE
Shiny/may have shiny color - Answer -Metal
A characteristic that can be observed or measured without changing the composition
Ex:
Color
Smell
Boiling Point
Mass
Temperature
Volume - Answer -Physical Property
All metals have this
It is a physical property - Answer -Malleability
A characteristic that can only be determined by changing the chemical identity of a
substance
Ex:
Reactivity with water
Reactivity with acid
pH
Flammability - Answer -Chemical Property
Material made up of two or more substances that are physically mixed but not
chemically combined - Answer -Mixture
Transition from one state of matter to another - Answer -Phase Change
Does not affect the composition of a substance - Answer -Physical Change
The basic unit of matter - Answer -Atom
Neutrons
Electrons
Protons - Answer -Atoms contain..
How much matter it has - Answer -Mass
Positive
1 atomic mass unit - Answer -Protons
Negative
Small/negligible mass - Answer -Electron
, Neutral
1 atomic mass unit - Answer -Neutron
A collection of protons and neutrons at the center of the atom - Answer -Each atom has
an atomic nucleus
The space in which electrons move within an atom - Answer -Electron Cloud
A substance that is composed of a single type of atom - Answer -Element
The number of protons in an atom - Answer -Atomic Number
Important in determining the chemical reactivity of different kinds of atoms - Answer -
Valence Electrons
1. Add electrons
2. Give away electrons
3. Share electrons - Answer -3 Ways to Create a Full Valence Level
When an atom interacts with another atom - Answer -Chemical Bond
Two atoms formed through a bond - Answer -Molecule
-The atoms are going to share electrons
-Very strong bonds
-Most molecules are made up of these bonds - Answer -Covalent Bonds
Decides if the atom will:
Share, take, or donate electrons - Answer -Electronegativity
A charged atom - Answer -Ion
A positively charged ion - Answer -Cation
A negatively charged ion - Answer -Anion
-Two ions that have opposite charges are attracted to each other; a bond between the
atoms is formed
-One atom gives an electron to another atom and we end up with two ions - Answer -
Ionic Bond
-A pure substance that cannot be broken down by chemical methods into simpler
components
-Only consist of one type of atom - Answer -Element
