Ionic Bonding Flashcards
What is ionic bonding?
Ionic bonding involves the transfer of electrons in the outer shells between metals and nonmetals
What happens to metals in ionic bonding?
Metals lose electrons and become positively charged ions
What happens to nonmetals in ionic bonding?
Nonmetals gain electrons to become negatively charged ions
How can the electron transfer during the formation of an ionic compound be shown?
The electron transfer during the formation of an ionic compound can be represented by dot and cross diagram
What to include in a dot and cross diagram?
. The correct number of electrons on outer shells
. The charge
Describe the structure of an ionic compound
Ionic compounds have a lattice structure with a regular arrangement of ions held together by strong electrostatic forces between oppositely charged ions. The ionic bonds act in all directions
Do ionic compounds have a high or low melting and boiling point and why?
Ionic compounds have a high melting and boiling point because of the large amounts of energy needed to break the many strong bonds. They are usually solid at room temperature.
What happens to ionic compounds when they are melted or dissolved in water?
They conduct electricity because the ions are free to move and so charge can flow
