What is Newtons First law of motion? Give an example.
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Ex. You push a ball down a hill. The ball will continue until a force or something else stops it.
What does the atomic number tell us about an element?
The number of protons in the nucleus.
What is an element, list an example.
an element is, a pure substance that CAN NOT BE BROKEN DOWN; into simpler substances.
Ex. Gold (Au) or Oxygen (O)
What is Newtons Second Law of Motion, give an example.
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
Ex. The more you push a swing, the more force is applied.
What is the arrangement of elements on the Periodic Table?
The periodic table is arranged in order of atomic number.
What is a compound, list an example.
a compound is made up of two or more types of elements; that are "CHEMICALLY" combined.
Examples include: water, carbon dioxide, or rust.
What is Newtons Third Law of Motion, provide an example.
For every action there is an equal and opposite reaction.
Ex. Sitting on a skateboard, you throw a ball against the wall. Your movement is results in the same amount of force in which you applied.
What is a period and a group on the periodic table?
A period (row) is a horizontal row (side to side) on the periodic table.
The groups (columns) are vertical columns (up and down) on the periodic table, also called families.
What is a mixture, provide an example.
a mixture is a substance made by mixing other substances; and they are combined together.
Ex. Trail mix, salt water, or air.
What is a family on the periodic table and what do all families have in common?
The groups (columns) are vertical columns (up and down) on the periodic table. They are called families because of their "similar chemical behavior". All members of a family have the same number of valence electrons and similar chemical properties.
What is the atomic number, symbol, chemical name, and atomic mass of Boron?
Atomic #- 5
Symbol- B
Name- Boron
Atomic Mass #- 10.811
What of the following are examples of a mixture? a.milk b.cheese c.wheat thins d.carbonated soda
The answer is a. and d. because they both include substances made up of other substances.
What is Matter?
is anything made up of atoms and molecules.
