Bonding Flashcards
1
Q
what is a covalent bond
A
the sharing of a pair of electrons between 2 atoms
2
Q
what is electronegativity
A
the power of an atom to attract the pair of electrons in a covalent bond
3
Q
what scale is electronegativuty graded on
A
the pauling scale
4
Q
what is the most electronegative atom and why
A
Fluorine
because it has a small atomic radius and high nuclear charge
5
Q
what does electronegativity depend on (3)
A
1) atomic radius (smaller the greater)
2) nuclear charge ( higher the greater)
3) number of principle energy levels (fewer the greater)
6
Q
where is electronegativity greatest on periodic table
A
more up and right
