Bonding Flashcards
What happens to the electrons in an ionic bond?
Electrons are transferred between atoms; donating and receiving
What type of elements are an ionic bond between?
Metal and non-metals
Is an ionic bond a weak or a strong bond?
Strong bond
How is an ionic bond held together?
Electric charge
What is the name of the compound NaCl?
Sodium chloride
What is the name of the compound MgCl?
magnesium chloride
What is the name of the compound K2S?
Potassium sulfide
What is the name of the compound BeO?
Beryllium oxide
What is the molecular formula for the compound sodium nitride?
Na3N
What is the molecular formula for the compound lithium oxide?
Li2O
What is the molecular formula for the compound magnesium bromide?
MgBr
What is the molecular formula for the compound calcium flouride?
CaF2
What is the molecular formula for the compound sodium sulfate?
Na2SO4
What is the molecular formula for the compound magnesium nitrate?
Mg(NO3)2
What is the molecular formula for the compound barium hydroxide?
Ba(OH)2
What is the molecular formula for the compound calcium phosphate?
Ca3(PO4)2
What is the name of the compound KOH?
Potassium hydroxide
What is the name of the compound Li3PO4
Lithium phosphate
What is the name of the compound NH4Cl?
Ammonium chloride
What is the name of the compound MgSO4?
Magnesium sulfate
What happens to electrons in a covalent bond?
Electrons are shared
What type of elements are covalent bonds between?
Non-metals and non-metals
Is a covalent bond a weak or a strong bond?
Weak bond
What is a diatomic molecule?
Molecule made up of two of the same type of atom (Ex. H2)
How many covalent bonds hold together two hyrdrogen atoms?
1
How many covalent bonds hold together two oxygen atoms?
2
How many covalent bonds hold together two nitrogen atoms?
3
What is a polar covalent bond?
Unequal sharing of electrons
How do polar molecules behave in solutions?
The partially positive side of one polar molecule is attracted to the partially negative side of the other polar molecule, causing the solute to dissolve into solution.
In H2O, which atom(s) have the partial postive charge and which have the partial positive charge?
The O is partially negative because it has a stronger pull on the electrons while the H is partially positive
What is the difference between an ionic compound and a molecular compound?
Ionic compounds involve atoms interacting through ionic bonds while molecular compounds involve atoms interacting through covalent bonds
How is NaCl dissolved in H2O?
The partial negative side of H2O is attracted to the positive Na ion while the partial positive side of H2O is attracted to the negative Cl ion. H2O eventually surrounds each ion and causes it to dissolve
What is a non-polar molecule?
A molecule without any partial or full charge (Ex: oil)
Why don’t oil and water mix?
Oil is a non-polar molecule while water is a polar molecule. They are not attracted to each other because oil does not have a chagre while water has positive and negative ends.
What is a hydrogen bond?
The partially positive H of one water molecule being attracted to the partially negative O of another water molecule
What is a polar molecule?
A molecule with a partially positive and partially negative side
