A lone pair is defined as

A pair of non-bonding electrons

A pair of electrons on the central atom

When figuring out Lewis Dots for Covalent compounds what does "A" mean?

A = the total available valence electrons of all the atoms

A = the available valence electrons of one atom

A = the total valence electrons the atoms wants to have in its outer shell

A = the number of shared electrons

What does the "N" mean when figuring out Lewis Dots for covalent compounds?

N = the total number of valence electrons NEEDED in the outer shell

N = how many more valence electrons are needed

N = how many valence electrons are available to share

What would the "A" be for CH 3 F when figuring out the Lewis Dot?

(1 x 4) + (3 x 1) + (1 x 7) = 14

(1 x 8 ) + (3 x 2 ) + (1 x 8) = 22

Which atom goes in the middle of the Lewis Dot structure?

The one that needs the most or is less electronegative generally

The one the needs the least number of valence electrons

The most electronegative element

Electronegativity is...

how good an atom is at attracting electrons

the ability of an atom to lose electrons

the energy required to remove an electron from a specific atom

how easy it is to make friends.

The polarity of a bond is determined by...

The difference in the electronegativities of the two atoms

The sum of the electronegativities of the two atoms
