Ionic Bonds and Ionic Compounds Flashcards
ionic bond
the electrostatic force that holds 2 oppositely charged particles together in an ionic compound
ionic compound
compounds that contain ionic bonds
oxides
if ionic bonds occur between metals and the nonmetal oxygen
salts
most other ionic compounds
binary compounds
a compound that contains a metallic cation and a nonmetallic anion
binary
a compound that contains only 2 elements
what determines the ratio of positive and negative ions
the number of electrons transferred from a metal atom to a nonmetal atom
ionic crystals
the result of an ionic compound. it has a highly organized nature with a constant spacing of ions and a uniform pattern.
formation of crystal lattice
the strong attraction among the positive ions and negative ions in an ionic compound
crystal lattice
a 3 dimensional geometric arrangement of particles
physical properties
melting point , boiling point and hardness. they are determined by the strength of electrical forces between particles in matter. ionic crystals have high melting and boiling points and are hard to break
electrolytes
an ionic compound whose aqueous solution conducts electric current , in ionic compound solutions ions move freely thus they can conduct electricity unlike when they are solids
endothermic
reactions that absorb energy
exothermic
reactions that release energy ; ion formation
lattice energy
the energy required to separate 1 mol of ions from an ionic compound , the greater the lattice energy the stronger the force of attraction
