QuestionAnswer
Are there few or many electrons in the outermost energy level of metals?few
What is the difference between malleability and ductility?bend vs. stretch
What are the two types of covalent bonds?pure covalent and polar covalent
How does electronegativity change as you move from left to right across the periodic table?increase
What type of elements form ionic bonds?metals and nonmetals
Give an example of a polar covalent bond?answers may vary
How can we use the periodic table to help us determine the type of bonding between atoms?Trends in electronegativity and metals vs non metals
Why do we only consider Valence electrons in drawing Lewis structures?they are the ones that react
The relative ability of an atom in a molecule to attract electrons to itself is called the atoms ___________.electronegativity
What is a dipole moment?; draw an example.electrical effect that occurs in molecules with separate centers of positive and negative charge.
What does it mean when we say that in forming bonds, atoms try to achieve an electron configuration of a noble gas?most stable configuration.
Double point questions! Why are cations always smaller than the atoms from which they were formed?loss of e so one valence shell is lost
Explain the difference between the duet and the octet rule. Give an example of an atom that follows each.H and O
Write the Lewis structure for Sr.see notes
Write the Lewis structure for C2F6.see notes
Write the Lewis structure for N2H4.see notes
Write the Lewis structure for the sulfate ion.SO4 2-
What does it mean for a molecule to exhibit resonance?more than one lewis structure
Write the Lewis structure for the barium ion. Ba2+
What general principles determine the molecular structure (shape) of a molecule?how many e pairs surround, which pairs used for bonding
Come to the classroom and build a model of one of the molecules listed by the parts kit.see models
