Atoms & Elements
On the periodic table, it's the information on each tile that indicates the number of protons in the element.
What is the Atomic Number?
The type of measurement derived by multiplying two length measurements.
What is an Area?
A molecule made of the combination of metal and nonmetal elements.
What is an Ionic Compound?
Energy cannot be created or destroyed. It can only change form.
What is the First Law of Thermodynamics?
What is Condensing?
The name given to the elements in the right-most column of the periodic table.
What are the Inert or Noble Gasses?
The fundamental unit of volume in the metric system.
What is the Liter?
A molecule made of multiple atoms that has a net electrical charge.
What is a Polyatomic Ion?
The molecules or atoms that make up a substance are in constant, random motion. The hotter the substance, the faster the motion.
What is the Kinetic Theory of Matter?
The amount of a solute that can be dissolved in a specific amount of solvent.
What is Solubility?
Atoms of the same element that have different numbers of neutrons.
What are Isotopes?
The fundamental units shown on each tile of the periodic table that also stand for grams per mole of that particular element.
What are Atomic Mass Units?
A molecule consisting of two atoms of the same element.
In any chemical or physical process, the total mass of everything must remain the same.
What is the Law of Mass Conservation?
The term for a substance's ability to be bent and shaped without breaking easily. This is common of most metals.
The name for the elements that make up the "B" columns in the middle of the periodic table.
What are the Transitional Metals?
The name given to the way a liquid level looks curved when looking at fluid in a graduated cylinder.
What is a Meniscus?
A molecule that has an even distribution of electrons, resulting in no charges within the molecule itself.
What is a Purely Covalent Molecule?
The entropy of the universe can never decrease. It must always stay the same or increase.
What is the Second Law of Thermodynamics?
When a substance changes from the solid phase directly to the gas phase.
What is Sublimation?
The name for the most accurate understanding of the structure of an atom.
What is the Quantum Mechanical Model?
The fundamental unit of mass in the English system.
What is a Slug?
The type of molecular structure that is flat and has bond angles of 120 degrees.
What is Trigonal?
A given compound will always have the same proportion of elements by mass.
What is the Law of Definite Proportions?
The spontaneous breakdown of an atom's nucleus, which often changes the element to which the atom belongs.
What is Radioactive Decay?
