Bond Polarity

In covalent bonds, electrons are (a)  

• shared
• transferred
• gained
• lost

In a polar covalent bond, electrons are shared .
(a)  

• unequally
• equally
• between non-metals with similar electronegativities
• between a metal and a non-metal

Electronegativity is a measurement of the ability of a nucleus to...

• attract bonding electrons
• attract other nuclei
• attract elenece in the non-valence energy levels

How many electrons are represented by a single straight line in a Lewis structure?

• 1
• 2
• 4
• 6

The most electronegative atom in the periodic table is:

• Fluorine
• Helium
• Neon
• Francium

In this Lewis structure, the partial charge symbol above F means...

• electrons are being transferred to Fluorine

• electrons are less attracted to F than H

• electrons are more attracted to F than H

• Fluorine has formed a cation
