When two atoms share one or more pairs of electrons.
What is a Covalent Bond?
100
When valence electrons are transferred from one atom to another atom.
What is Ionic Bonding?
100
It is a bond formed by the attraction between positively charged metal ions and the electrons around the ions.
What is Metallic Bond?
100
By only using the electrons in the outermost energy level.
How do atoms form bonds?
100
An electron in the outermost energy level of an atom.
What is Valence Electron?
200
Is usually made of two or more atoms
What is a mollecule
200
A charged particle that forms when an atom or group of atoms gains or loses one or more electrons
What is an ion?
200
The properties metallic bonding gives metals is conductivity,malleability,and ductility.
What are the properties that metallic bonding gives metals their particular properties?
200
No atoms dont all bond the same way and some atoms dont even bond at all.
Do all atoms bond the same way?
200
You determine it by knowing the number of valence electrons in the outermost energy level of the atom.
How can you determine if an atom will form any bonds?
300
It is a model that shows only valence elctrons in an atom
What is an electron dot diagram
300
The regular pattern in which a crystal is arranged
What is a crystal lattice?
300
Attracted to metal ions and also form metallic bonds
What is a free moving electron?
300
No atoms of the noble gases group usually dont bond.
Do noble gas atoms form bonds?
300
Yes atoms with less then eight valence electrons usually bond becuase there outermost energy cloud is not yet full.
Do atoms with less than eight valence electrons bond?
400
The simplest but most important molecules we could not live without including oxygen and hydrogen
What is a diatomic molecule?
400
When ions make a strong attraction that form a crystal lattice
What is an ionic compound?
400
To reshape something that bends instead of breaking
What is malleability?
400
The atoms dont bond because eight is the magic number and when an atom has eight electrons in the outermost energy level it means it is full and it doesnt need or want anymore.
Why do atoms with eight electrons in there outermost energy level not not bond?
400
No not all atoms need eight valence electrons to be full for example helium only needs two valence electrons to have a full outermost energy level.
Do all atoms need eight valence electrons to be full?
500
The basis of many complex molecules that make four covalent bonds to have 8 valence electrons
What are carbon atoms?
500
A certain group of elements on the periodic table whose characteristics are very brittle, dull and a poor conductor of electricity
What is a non metal?
500
When an object is a good conductor of electricity (usually a metal)
What is conductivity?
500
The joining of atoms to form new substances.
What is chemical bonding?
500
Atoms have positive ions when they lose valence electrons and atoms have negative ions when it gains electrons.
When do atoms have positive ions and when do atoms have negative ions?
