electronegativity Flashcards
1
Q
what is the definition of electronegativity?
A
the ability for an atom to attract electrons towards itself in a covalent bond
2
Q
how does electronegativity change in periodic table?
A
the further up and right you go in periodic table (excluding noble gasses) the more electronegative the element is
fluorine is the most electronegative
3
Q
what scale shows us how electronegative an element is ?
A
pauling scale
4
Q
what bonds do atoms have if they have a different electronegativity ?
A
polar bonds
5
Q
what does the more electronegative atom in a bond do ?
A
pulls electrons towards itself
6
Q
why does electronegativity increase from lithium to fluorine?
A
More protons / bigger nuclear charge
Same or similar shielding / electrons in the same shell
atoms get smaller
