2.3 Study Guide Flashcards
What happens with electrons during ionic bonds?
Electrons are transferred to one atom.
What happens with electrons during covalent bonds?
Electrons are shared, or “fought” over.
What happens with electrons during polar covalent bonds?
Electrons are unequally shared. One has a high amount while the other has a higher amount.
What happens with electrons during nonpoplar covalent bonds?
Electrons are shared equally.
Electrons are shared equally is what?
Nonpolar covalent bond.
Electrons are transferred is what?
Ionic bond.
Electrons are shared unequally is what?
Polar covalent bond.
What’s the differences in properties between covalent and ionic bonds?
- Ionic bonds have solubility and electrical conductivity in water, they have high temperatures, and they’re usually solid.
- Covalent bonds don’t have electrical conductivity in water, and only some of them have solubility in water. They’re also mainly liquids and gases. They vary between solids, gases, and liquids, though.
What’s the difference between nonpolar and polar covalent bonds?
- Nonpolar covalent bonds share an equal amount of electrons. They have the same ends. Equal EN.
- Polar covalent bonds have an unequal amount of electrons. One is low and the other is high. They have opposite ends. High EN and higher EN.
What kind of bond will form between Boron and Fluorine? Please explain.
A covalent bond because they’re both nonmetals, and covalent bonds are created by two nonmetals.
What kind of bond will sodium and chlorine form?
Ionic bond because they are opposites and opposites attract to create ionic bonds.
Explain how electrongetivity determines what type of bond two atoms will form.
It depends on the electronegtivity because in an ionic bond, they’re ions because one’s electronegativity is low while the other is high, making them opposites and attract. Electronegativity helps explain what kind of bond two atoms will have by telling us the difference in EN, and then comparing them and deciding.
