Chemical Bonds
What is the free electron theory?
Electrons in a metallic bond are freely moving between many shared cations (nuclei)
Compare and contrast electron affinity and electronegativity.
both - attraction for and ability to hold electrons
electron affinity - unbonded atoms
electron negativity - bonded atoms
When do polar covalent bonds occur?
Draw the Lewis dot structure of CH4.
CH4
What are the three types of chemical bonds?
covalent, ionic, metallic
Draw the transfer of electrons in an ionic bond between sodium and chlorine. When these element are combined, what is the charge on each atom
NA + Cl-
Why do atoms form bonds?
to become stable and achieve an octet
How can we use our knowledge of atoms, how they bond, and their properties in dominion science?
make things that help people, medicine
