Bonding Flashcards
When two or more atoms bind, they form a
Chemical bond
A chemical bond is the
Force that holds the atom together
Atoms form chemical bonds to _ and become more stable
Complete their outer energy levels
Only the _ form chemical bonds
Valence electrons
Atoms form bonds according to the _ rule
Octet
Octet means
A group of 8
(Octet rule) elements combine in such a way that each atom has a
Complete outer energy level (which is eight for many elements)
(Octet rule) to have a complete outer energy level, atoms _ from each other to balance their electron count
Give up or take electrons
The valence number of most atoms can be determined by
Their location on the periodic table
Sodium is in the first group on the periodic table and has _ valence electrons
One
Chlorine is in the seventh group and has _ valence electrons
Seven
Transition metals usually have either _ or _ valence electrons
Two
Three
Some transition metals can have as many as _ or _ valence electrons
5
6
Atoms bond to complete their outer energy level and
Become more stable
_ are the most stable elements
Noble gases
All other elements want to be stable like
Noble gases
The type of bond that atoms form determines
How stable they will become
Three main type of bonds are (3)
Ionic
Covalent
Metallic
Ionic bonds are formed when one atom donates, another accepts and
Bond is formed by attraction between the newly formed ions
Ionic bonds occur between _ and _ ions
Metal
Nonmetal
In covalent bonds, two atoms _
Share electrons between them
Covalent bonds occur between two
Nonmetals
In metallic bonds, atoms are connected via
A “sea of electrons”
Metallic bonds can only occur between
Metals
