2.3 Study Guide Flashcards
What happens to electrons during ionic bonding?
The atom with higher electronegativity pulls all the electrons to its orbit ultimately creating a “bond” however electrons are not shared.
what happens to electrons during polar covalent bonds?
The electrons are shared unequally thus making a bond. Since there is a slight difference in electonegativity the atom with a higher electronegativity takes more electrons.
What happens to electrons during non-polar covalent bonds.
The electrons are shared equally between the two atoms because they have a similar or equal electronegativity.
Is this a polar or non polar bond? Cl bonded with Cl
non-polar bond
Is this a polar or non polar bond?: F bonded with H
polar bond
Is this a polar or non polar bond?:Al bonded with Si
non-polar bond
What is a polar covalent bond?
A polar bond is that is formed between one atom with a higher electronegativity than the other causing a bond by the attraction the one with the higher EN has to the electrons to the on with a smaller EN.
What is a non polar covalent bond?
A non polar bond is a bond formed between two atoms with the same or similar EN which causes an equal force bringing the bond together and having the electrons shared equally.
How does electronegativity determine what bond will form?
The electronegativity is basically how much an atom attracts electrons. Based off the EN you could have a polar, non polar, or ionic bond. If you have atoms with a different EN you could have a Ionic or Polar bond but if you have atoms with the same EN you will have a non polar bond.
