Ionic
How do you name ionic compounds?
You ignore the subscripts and list the cation name followed by the anion name
What is a Covalent compound ?
Two non-metals combined or a molecule formed by covalent bonds.
What is a Chemical Reaction?
a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
Define Molecule
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
What is a Coefficient?
the number preceding an elemental symbol, telling how many molecules of whatever element or compound.
What is the Chemical name for NaCl?
Sodium Chloride.
What is the name of this covalent compound P4 O10 ?
Is it tetraphosphorus decaoxide?
What is a Chemical and Physical Change?
During this type of change new substances form. For this one it changes its appearance of a substance only.
Define Metal
elements on the bottom left side of the black line in the periodic table, generally conductive.
What is a Product?
the result(s) of a chemical reaction.
What is the chemical name for LiBr?
Lithium Bromide.
Are these two compounds CoBr2 and N2O3 Covalent ?
Nope, because the first compound is Ionic(metal,nonmetal) and the second is Covalent(nonmetal,nonmetal).
What are Physical Properties?
Changes, such as color and odor, indicate a chemical reaction.
Define Non-Metal
those elements on the upper right side of the black line on the periodic table, generally not conductive
What is a Reactant?
a substance that takes part in and undergoes change in a chemical reaction.
What is an Ionic Compound?
groups of ions which tend to form crystalline structures.
What are Valance Electrons?
An electron that is found in the outermost energy level of an atom, and that determines the atom's chemical properties.
Chemical Properties
the only way to be certain that a chemical reaction has taken place is to compare blank of the change before and after the change.
What are superscripts?
The small number/s above an elements symbol
What are Subscripts?
A chemical formula contains element symbols and blank to describe the make-up of a compound.
What is an Ionic Bond?
a chemical bond formed between two ions of different charges (cation/anion) (metal/non-metal)
What is a Covalent Bond?
A bond formed when atoms share one or more pairs of electrons.
What is a Chemical Bond?
a lasting attraction between atoms that enables the formation of compounds.
What types of Ions are there? And what do they represent?
A cation(+ lose electrons) and Anion(- gain electrons)
What creates a balanced Chemical Equation?
each side of the equation has the same number of atoms of each element and mass is conserved.
