2.3- Study Guide Flashcards
What happens with electrons during an ionic bond
During an ionic bond an electron is transfered from one element to another element
Differences in properties between ionic and covalent bonds
IONIC BOND
-high melting and boiling points
-usually don’t conduct electricity, but they can conduct electricity
-typically between a metal and a non-metal
-water soluble
COVALENT BOND
-generally not soluble in water
-lower melting and boiling points
-typically do not generate electricity
-between two non-metals
Differentiate between a polar and non-polar covalent bond
-a polar bond is when one element has a stronger pull on the electron, while
-a non-polar bond is when the pull for the electron is roughly the same
More than likely, what type of bond would a metal and a non-metal element form
an ionic bond would most likely form
Explain how electronegativity determines what type of bond two atoms will form
-a larger difference in electronegativity usually ends in an ionic bond, while
-a smaller difference in electronegativity usually ends in a covalent bond
What happens with electrons during polar covalent
During a polar covalent bond and electron is shared between two atoms, but one atom has a stronger attraction to the electron
What happens with electrons during non-polar covalent bonds
During a non-polar covalent bond an electron is shared between two atoms equally
What are the properties of an ionic bond
-transfers electron
-typically between a metal and a non-metal
What are the properties of a covalent bond
-shared electron(s)
-typically between two non-metals
What are some characteristics of a polar covalent bond
-share electron(s)
-one atom has a stronger attraction toward the electron
What are some properties of a non-polar covalent bond
-share electron(s)
-atoms have an equal pull on the electron being shared
More than likely, what type of bond would a non-metal and a non-metal element form
typically, a covalent bond would form between two non-metal elements
