Basic Introduction I Flashcards
This study section includes Electron Configuration, Lewis Dot Structure, Octet Rule and Chemical Bonding
True or False
The lower energy level, the more stable an atom.
True
Attaining lower energy will achieve Octet Rule (8 electrons)
It is the process of adding or taking away outer shell electrons to gain a closed shell configuration.
Chemical Bonding
3 Rules of Electron Configuration
- Aufbau (build up)
- Hund’s (multiple sub-orbitals)
- Pauli Exclusion (opposite spins)
Fill
In a neutral atom, the # of protons is similar to the # of ______
Electrons
What electrons participate in chemical bonding?
Valence electrons
Core electron is also called as
Kernel
No. of valence electron also represents
Atomic Group Number
What is the maximum number of valence electron found in an s-orbital?
Two (2)
What is the maximum number of valence electron found in an p-orbital?
Six (6)
Because it has 3 sub-orbitals (px, py, pz)
What is the rule’s name?
An atom requires full valence
Octet Rule
Are noble gases reactive or unreactive
Unreactive
Noble gases are unreactive because they are stable.
What is the most reactive group number in the periodic table?
Group VII
Flourine belongs to Group 7 which is the most reactive element.
How to identify the charge of an atom?
Count the number of protons, subtract the same number + the # it needs to attain Octet Rule.
What?
Positive Ion
Cation
This can be simply remembered by considering “t” as “+”
What?
Negative Ion
Anion
Prefix “an” means missing
Theory/Principle?
Atoms transfer or share electrons to gain filled valence shell of electrons
Lewis Bonding Theory
What is?
It is the transfer of electron to form ions
Ionic bonding
aka Electrovalent bonding
Who?
Proponent of Lewis Bonding Theory
Gilbert N. Lewis
Fact: Never won a Nobel prize
