Chapter 1
Something that must have volume and must have mass. Must take up space in general.
What is the definition of matter?
Contains chemical symbols
What is a chemical formula?
The sum of protons and neutrons in an atom.
What is atomic mass?
An area around the nucleus of the atom which contains electrons of equal energy.
What is an electron shell?
Isomers have the same molecular formula, different structural formulas.
What is an isomer?
The curve formed by a liquid in a container.
Anything on the periodic table
What is an element?
A single piece of an element.
What is an atom?
Electrons in the outer most shell with the highest energy.
What are valence electrons?
o=c-o-h
What is the functional group that most likely indicates that the smell will be putrid?
Milliliters
When measuring volume in a graduated cylinder what is the unit of measurement used?
Two or more elements hooked together to form something new.
What is a compound?
What is an isotope?
Group 8A
Where are noble gases located on the periodic table?
Hydrogen-1 bond
Oxygen-2 bonds
Nitrogen-3 bonds
Carbon-4 bonds
How many bonds does each of the following have, hydrogen, nitrogen, carbon, and oxygen?
1. Color, 2. Phase, 3. Odor, 4. Volume, 5. Mass
What are 5 examples of physical properties of matter?
What is the difference between a chemical and a physical change?
Negative, positive, and neutral
What charge do electrons have? What charge do protons have? What charge do neutrons have?
Electrons
When ions form what is the only subatomic particle to transfer?
Valence electrons and lone pairs
What do a Lewis and Dot structure show that structural formulas do not?
By using water displacement method
How do you measure the volume of irregularly shaped objects?
If the chemical formula contains only one capital letter it is an element, if it contains more than one capital letter it is a compound.
What is one major way you can identify the difference between an element and a compound based on the chemical name?
First, multiply the mass of the isotope by its percent abundance. Then take the sum of all the steps from step one.
Always put the cation first, then the anion names change to end with -ide.
How do you name an ionic compound?
You would need 4 valence electrons.
If I had 4 valence electrons present in an atom how many more would I need to ensure the octet rule is used?
