Ionic compounds

Cards (13)

What are ionic compounds formed from?
Oppositely charged ions
What is an ionic bond?
A strong attraction between cations and anions
What creates stable compounds like table salt?
Transfer of electrons between atoms
What are the two types of ions in ionic compounds?
Cations and anions
How are cations formed?
When an atom loses one or more electrons
How are anions formed?
When an atom gains one or more electrons
What typically happens between elements with large differences in electronegativity?
Electron transfer occurs
What charge do anions have?
Negative charge
What is Coulomb's Law?
Force is proportional to charge product
What charge do cations have?
Positive charge
How is the electrostatic force expressed mathematically?
$F =$ $k \frac{q_{1} q_{2}}{r^{2}}$
What does the electrostatic attraction do in ionic compounds?
It pulls cations and anions together
What are the two key processes in the formation of ionic compounds?
Electron Transfer
One atom loses electrons
Forms cations and anions
Electrostatic Attraction
Cations and anions attract each other
Forms ionic bonds
