An object that holds solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated. (Not used for exact measurements)
What is a beaker?
100
A substance that contains only one type of atom.
What is an element?
100
This group consists of alkali metals.
What is Group 1?
100
The mutual electrical attraction between the nuclei and valence electrons
What is a chemical bond?
100
Shows how valence electrons are arranged among atoms in a molecule. Reflects central idea that stability of a compound relates to noble gas electron configuration.
What is a Lewis Structure?
200
An object used to measure volumes of liquids.
What is a graduated cylinder?
200
A substance made by bonding atoms together in specific ways. These substances contain two or more different types of atoms.
What is a compound?
200
This group consists of Alkaline Earth Metals.
What is Group 2?
200
The transfer of electrons. (Cations and Anions)
What is an ionic bond?
200
Similar stuctures when more than one valid dot diagram is possible.
What is a resonance structure?
300
An object used to manually stir/mix solutions. It can also be used to transfer a single drop of a solution.
What is a glass stir rod?
300
The smallest particle of an element that retains the chemical properties of that element.
What is an atom?
300
Elements that have properties that are intermediate between metals and nonmetals. Also called semimetals.
What is a metalloid?
300
The sharing of electrons.
What is a covalent bond?
300
Predicts the three dimensional shape of molecules. Valence-shell-electron-pair-repulsion.
What is the VSEPR Theory?
400
An object used for the heating of stable solid elements and compounds.
What is an evaporating dish?
400
Atoms of the same element that have different masses.
What is an isotope?
400
The amount of energy required to remove one electron from a neutral atom.
What is ionization energy?
400
Bonds that form when electronegativity difference is between 0.3 and 1.7.
What is a polar-covalent bond?
400
The energy required to break a chemical bond and form neutral isolated atoms.
What is bond energy?
500
An object used to weigh solids that will be transfered to another vessel.
What is a weighing boat?
500
The general term for a specific isotope of an element.
What is a nuclide?
500
Half the distance between the two nuclei of a diatomic molecule.
What is atomic radius?
500
A bond that forms with an electronegativity difference of 0.1 to 0.3.
What is a mostly Non-Polar Covalent bond?
500
A compound created by simple units of molecules- shown by molecular formula.
