Chemical Bonding Flashcards
It is the formation of a chemical bond between two or more atoms.
Chemical Bonding
He is an American physical chemist whose concept of electron pairs led to modern theories of chemical bonding, and he developed the “Lewis Electron Dot Structure”.
Gilbert Lewis
What is Gilbert Lewis’ famous paper?
The Atom and the Molecule”
It is the single electron or two or more electrons in the outermost energy level of an atom and is responsible for the chemical properties of the atom.
Valence electron
It indicates the number of electrons in an element’s outermost energy shell.
Group number
It indicates the number of shells of an element.
Period number
It states that an atom needs to attain 8 valence electrons in its outermost energy level to become stable.
Octet Rule
It is the ability of an atom to accept electrons.
Electron Affinity
It is the ability of an atom to attract electrons.
Electronegativity
What element has the highest ability to attract more electrons when bounded?
Fluorine (F)
What are the three types of Chemical bonding?
(1) Ionic Bonding
(2) Covalent Bonding
(3) Metallic Bonding
It is a type of bond that involves the complete transfer of valence electron(s) from one atom to another.
Ionic bonding (Metal + Nonmetal)
What is the other term for Ionic bonding?
Electrovalent bond
What is the electronegative difference to predict the ionic bond?
More than 2 units
It is the bonding between sodium and chlorine that causes a strong attraction.
Electrostatic force
It is a type of bond that is characterized by the sharing of electron pairs between two atoms.
Covalent Bonding (Nonmetal + Nonmetal)
What is the other term for covalent bonding?
Molecular bond
What is the electronegative difference to predict the covalent bond?
Less than 2 units
These are the nonbonding pairs also called unshared pairs that are not involved in the sharing of electrons as represented by the single line.
Lone Pairs
It is the number of bonding pairs of electrons between two atoms.
Bond order
It is responsible for the formation of metals.
Metallic Bonding (Metal + Metal)
These are all of the atoms in a small piece of metal that share a big pool of valence electrons.
