Bond Basics
What type of bond forms when electrons are shared?
What is a covalent bond?
Name one diatomic element?
What is hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, or iodine
How many electrons are shared in a single bond?
What is 2?
What is the prefix meaning "four"?
What is tetra-?
What type of elements form metallic bonds?
What are metals?
What type of elements usually form covalent bonds?
What are nonmetals?
How many atoms are in a diatomic molecule?
What is two?
How many valence electrons does carbon have?
What is 4?
What is the name for the compound CO?
What is carbon monoxide?
What is the property called that allows metals to conduct electricity?
What is conductivity?
What are valence electrons?
What are electrons in the outermost energy level of an atom?
Which is diatomic: C, O₂, Na, Ne?
What is O₂?
How many total valence electrons are in CO₂?
What is 16?
What is the formula for dinitrogen pentoxide?
What is N₂O₅?
What is the "sea of electrons"?
What is valence electrons that are free to move throughout the metal?
Why do atoms form covalent bonds?
What is to fill their valence shell and become more stable?
Why is nitrogen found as N₂ instead of single N?
What is because nitrogen atoms share electrons to fill their valence shells and become stable?
Draw a Lewish dot structure for NH₃?
8 total valence electrons, single bonds to H, lone pair on N
What is the name for the compound SF₆?
What is sulfur hexafluoride?
Why are metals malleable?
What is because metal cations can slide past each other while electrons hold them together?
Explain the difference between covalent and metallic bonds?
Covalent bonds involve sharing electrons between nonmetals
Metallic bonds involve positive metal ions surrounded by a sea of delocalized electron
What is the chemical formula for chlorine in nature and why?
What is Cl₂, because chlorine atoms share electrons to complete their valence shells?
Draw a Lewis dot structure for CO₃²⁻ (carbonate)?
24 total valence electrons, 2 single-bonded O w/ 3 pairs each, 1 double-bonded O w/ 2 pairs, show -2 charge
When naming a compound, how do you know when to use prefixes (mono, di, tri, etc.)?
What is when the compound is covalent, made of two or more nonmetals?
Explain how metallic bonding allows copper to conduct electricity and form wires?
What is because the delocalized electrons move freely, allowing electricity to flow and letting metal atoms slide into wire shapes without breaking bonds
