All this stuff
To count as matter, it needs to have these two properties.
What is mass and volume?
What is an atomic number?
The numbers that we write down from a measurement or calculation.
What are significant figures.
What is an element?
Matter cannot be created nor destroyed, only transformed.
What is the mass conservation law?
The simplest unit of matter that has chemical properties.
What is an atom?
Most of the mass in an atom is due to these particles.
What are protons and neutrons (nucleons)?
These types of values do not affect how many numbers the result of a calculation has.
What are exact numbers or counted numbers?
Properties matter demonstrates when attempts are made to change it into new substances.
What is a chemical property?
Atoms tend to gain or lose electrons according to this rule/pattern.
What is isoelectronic with their nearest noble gas?
A pure substance consisting of two or more kinds of atoms in the form of heteroatomic molecules or individual atoms.
What is a compound (or molecule)?
Cl-35 and Cl-37 are examples of these.
What are isotopes?
A unit obtained by multiplication or division of one or more basic units.
What is a derived unit?
Explanations for scientific laws.
What is a theory?
If you counted out 6.0 x 1023 atoms of carbon, this is how much it would weigh in grams.
What is 12 grams?
They are the seven diatomic elements.
What is hydrogen, nitrogen, fluorine, oxygen, iodine, chlorine, and bromine?
Electrons in atoms arrange themselves in this type of pattern.
What are shells (or energy levels).
DOUBLE JEOPARDY!!
The SI unit of amount.
What is a mole?
Also known as a solution.
What is a homogeneous mixture?
The element calcium belongs to this chemical family of the periodic table.
What are alkaline Earth metals?
A measurement of the gravitational force acting on an object.
What is weight?
This is the reason the atomic masses on the Periodic Table are rarely ever whole numbers.
What is an average of all the isotope masses for that element?
The number of micrograms in one kilogram.
What is 109 (a billion)?
This process means going from the solid state to the gas state.
What is sublimation?
DOUBLE JEOPARDY!!!
This technique can be used to determine the volume of irregularly shaped objects.
What is displacement?
