chemical Bonding Flashcards
(20 cards)
what a chemical formula is and how to count the total number of atoms 
Tells what elements a compound contains and the exact number of the atoms of each element in a unit of that compound 
Mg(OH)2
How many atoms are there? 
Five atoms 
What is an ion? 
An atom that has lost or gained electrons. It is a charged particle because the number of protons and electrons is no longer the same. 
What is an oxidation number? 
A positive or negative number that indicates how many electrons and atom has gained lost or shared to become stable 
is the oxidation number the same as the charge of an ion? 
yes 
What is covalent bonding? 
The attraction that forms between atoms when they share electrons 
What is ionic bonding? 
The force of attraction between the opposite charges of the ions in an ionic compound it involves the transfer of electrons 
How does ionic bonding form from? 
They form from metals bonding with nonmetals 
What does covalent bonding form from? 
It forms from bonding nonmetals with nonmetals 
How many electrons does an atom need to be stable
Eight electrons 
Why will noble gases not bond?
already has stable amount of electrons so it won’t bond 
What is the difference between a subscript and a superscript?
A subscript is written low and a superscript is written high 
what is a binary compound made up of?
it’s made up of two different elements 
The force of attraction between the opposite charges of the ions in an ionic compound 
Ionic bond
Compound composed of two elements
Binary compound bi means 2
Shorthand that tells what elements a compound contains in the exact number of atoms of each element in a unit of the compound
Chemical formula 
Describes an atom that has a full outer most energy level 
Chemically stable 
A charged particle that has either more or fewer electrons than protons
Ion
The attraction that forms between atoms when they share electrons
 Covalent bond 
Do you circle the electrons in an ionic bond?
No, only in a covalent bond (remember the c is a reminder to circle in an ionic bond you arrow)
