Methods of Science
Observe and ask a Question
Form a hypothesis
Collect data
Analyse data
Draw Conclusions
What is the scientific method?
A visual display of data.
What is a graph?
1s22s1
What is electron configuration?
This is a substance that cannot be broken down into smaller substances.
What is a element?
A positive ion
What is a cation?
This the variable that we are manipulating/changing.
What is an independent variable?
This can used to express any number as a number between 1 and 10 multiplied by 10 and raised to a power.
What is scientific notation?
The electrons found in the highest principal energy level
What are valence electrons?
This the left hand side of a chemical equation
What are reactants?
A negative ion
This is the variable that you are measuring.
What is a dependent variable?
This is a physical property of matter and is defined as the amount of mass per unit volume.
What is density?
This type of configuration uses noble gases
What is noble gas configuration?
This states that mass is neither created or destroyed in chemical reactions.
What is the law of conservation of mass?
This is a type of compound formed when two nonmetals join together.
What is a covalent compound?
As the independent variable increase, the other dependent increases.
What is a positive correlation?
This is how close a measured value is to an accepted value.
What is accuracy?
This is how easily an atom loses an electron.
What is ionization energy?
Synthesis, decomposition, single replacement and double replacement.
What are types of chemical reactions?
This is a polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms.
What is a oxyanion?
This type of data is numerical information.
These are all known digits and one estimated digit.
What are significant figures?
This diagram uses arrows.
What is a orbital diagram?
This states that a compound is always composed of the same elements in the same proportion by mass, no matter how large or small the sample.
These metals are able to have more than one oxidation number
What are transition metals?
