5-3: Periodic Trends: Electronegativity Flashcards
1
Q
Electronegativity
A
The ability of an atom to attract electrons to itself
2
Q
What are ionic bonds?
A
-transfer of electrons
-metals + nonmetals
-higher electronegativity difference
3
Q
Covalent bonds
A
-the sharing of electrons
-only nonmetals
4
Q
What are polar covalent bonds?
A
Unequal sharing of electrons
5
Q
What are non polar covalent bonds?
A
-Equal sharing
-when electronegativity difference is x <= 0.4
6
Q
What does high electronegativity mean?
A
-almost full shell
-smaller atoms
7
Q
Ionization energy
A
The amount of energy needed to remove an electron from an isolated gaseous atom
8
Q
What does high ionization energy mean?
A
High # of valence electrons
