Ionic Bonding Flashcards
What is an atom?
The smallest particle of an element that contains electrons surrounding a nucleus
What is a molecule?
A molecule is a group of two or more atoms chemically combined
How are ions formed?
Electron loss or gain
What are group 1,2 and 3 elements and what charge are they?
Metals and they are positive ions that lost electrons
What are group 5,6 and 7 elements and what charge are they?
Non-metals and they are negative ions that gained electrons
What charge are silver ions?
Ag+
What charge are copper ions?
Cu2+
What charge are iron ions?
Fe2+ or Fe3+
What charge are lead ions?
Pb2+
What charge are zinc ions?
Zn2+
What charge are hydrogen ions?
H+
What charge are hydroxide ions?
OH-
What charge are ammonium ions?
NH4+
What charge are carbonate ions?
CO3 2-
What charge are nitrate ions?
NO3-
What charge are sulfate ions?
SO4 2-
What is ionic bonding in terms of electrostatic attraction?
The electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion
Why do compounds with giant ionic lattices have high melting and boiling points?
Electrostatic forces are very strong so a lot of energy is needed to break the forces.
Why can ionic compounds only conduct electricity when molten and in aqueous solution?
Only then are the ions of the compound able to move around carrying a charge. A sea of delocalized electrons.
