05 - Ionic Bonding Flashcards
(26 cards)
What type of bonding does NaCl represent?
Ionic Bonding
What type of forces does this represent?
Electrostatic forces of attraction
Would you expect this compound to be a gas, liquid or solid and why?
Solid because the particles are tightly compared and arranged in a regular arrangement
Elements in Ionic Bonding
Non-metal and metal
How are the ions formed in Ionic bonding
Transferring electrons from the outer shell
Does the NaCl structure contain molecules?
No
What is the name of the NaCl structure
Giant ionic Lattice
Why do the elements: B,Si,C and Be not normally form ions?
Because they share by covalent bonding instead
Ammonium
NH4
Hydroxide
OH-
Nitrate
NO3-
Nitrite
NO2-
Hydrogen Carbonate
HCO3-
Carbonate
CO32-
Sulfate
S042-
Sulfite
SO32-
How many Cl- ions surround each Na+ ion?
6
What is the state at room temperature of all ionic compounds?
Solid
Half Equation for Ca2+
Ca –> Ca2+ + 2e-
Half Equation: O2-
O + 2e- —> 02-
Isoelectronic
They have the same number and arrangement of electrons
Why is the word molecule not used for ionic compounds?
An ionic compound is a substance composed of charged particles
Why do ionic compounds have high melting and boiling points?
Because of the large amounts of energy needed to break the many strong bonds
Why is the melting point of magnesium oxide higher than that of sodium chloride?
Magnesium and oxygen ions have greater charges than sodium and chloride ions, and are smaller in size
