Bond Formation
This shows what elements of a compound contain and the exact number of atoms of each element in a unit of the compound.
What is a chemical formula?
This is a charged particle that has either more or fewer electrons than protons.
What is an ion?
This is a positive or negative number that indicates how many electrons an atom has gained, lost or shared to become stable.
What is oxidation number?
When naming compounds the name of the positive ion or ________ goes first.
What is the cation?
This is a positively or negatively charged, covalently bonded group.
What are polyatomic ions?
This diagram contain the chemical symbol of an element and dots around it indicating its valence electrons.
What is an electron dot diagram?
This type of bond occurs when electrons are given or received forming ions as a result.
What is an ionic bond?
When two elements make a compound they are called this.
What are binary compounds?
This is the name for the following formula: CuCl. Use table 2 p. 566 to answer.
What is copper (II) chloride?
This is a compound that has water chemically attached to its atoms and written into the chemical formula.
What is a hydrate?
This group of elements is unique because all of its outer levels (valence electrons) are full.
What are the noble gases?
This attraction forms when electrons are shared between atoms.
What is a covalent bond?
This is the formula for Li1+ and N3-.
What is Li3N?
When naming elements in binary compounds you add this to the end of the anion.
What is -ide?
This is the formula for the hydrate cobalt chloride.
What is CoCl2 . 6 H2O?
These elements tend to give up an electron in a bond.
What are metals?
When covalent bonds share electrons equally it is called this.
What is nonpolar?
This is the formula for potassium sulfide. Use periodic table p. 566
What is K2S?
When naming covalent compounds scientists use Greek prefixes to indicate the number of atoms. This is how you would write N2O5. See page 570 table 6.
What is dinitrogen pentoxide?
A neutral particle that forms as a result of electron sharing is called this.
What is a molecule?
Hydrogen and oxygen tend to do this with their valence electrons when forming bonds with each other and other elements.
What is share electrons?
Water is an example of a polar bond because it has a slightly positive end at the ___________ side and a negative end at the ___________ side.
What is hydrogen and oxygen?
This is the formula for lead(IV) phosphide. Use periodic table p. 566
What is Pb3P4?
Sr(OH)2 is called this.
What is strontium hydroxide?
This type of bond occurs usually between metals and nonmetals.
