question and answers




ADMIN
[COMPANY NAME] [Company address]

,formal charge - Correct Answers: group # - lone pairs (NBE) - bonds (1/2 valence electrons)



valence electrons - Correct Answers: electrons in the outer most shell



Atom - Correct Answers: Smallest particle of an element



protons+neutrons surrounded by electrons



octet rule - Correct Answers: States that atoms lose, gain or share electrons in order to acquire a full set
of eight valence electrons



Pauli Exclusion Principle - Correct Answers: An atomic orbital may describe at most two electrons, each
with opposite spin direction



Aufbau Principle - Correct Answers: states that each electron occupies the lowest energy orbital
available first



Hund's Rule - Correct Answers: states that single electrons with the same spin must occupy each equal-
energy orbital before additional electrons with opposite spins can occupy the same orbitals



single bonds - Correct Answers: - Sigma bonds, contains two electrons.

* Permit free rotation



double bonds - Correct Answers: 1 sigma and 1 pi bond



triple bonds - Correct Answers: 1 sigma and 2 pi bonds



atomic number - Correct Answers: equal to the number of protons



neutrons - Correct Answers: equal to the atomic mass - atomic number

, isotopes - Correct Answers: where the same element has the same number of protons (mass number)
but different amount of neutrons, resulting in a different mass number (12C AND 13C)



shells - Correct Answers: n=1 1 shell 2electrons 1s2

n=2 2 shell 8 electrons 2s2 2p6

n=3 3 shell 18 electrons 3s2 3d10 3p6



ionic bond - Correct Answers: Formed when one or more electrons are transferred from one atom to
another

(metal/nonmetal)



covalent bond - Correct Answers: A chemical bond that involves sharing a pair of electrons between
atoms in a molecule



non polar covalent bond - Correct Answers: equal sharing of electrons



polar covalent bond - Correct Answers: unequal sharing of electrons



common bonding patterns: C - Correct Answers: 4 valence electrons

0 lone pairs

4 bonds



common bonding patterns: N - Correct Answers: 5 valence electrons

1 lone pair

3 bonds



common bonding patterns: O - Correct Answers: 6 valence electrons

2 lone pairs

2 bonds
