- atomic structure
- electron shells: 2,8,8,18,18
- electron shells: 2,8,8,18,18
- periodic trends
- more electrons=
denser=lower radius
- more electrons= greater need to complete
shell= higher electronegativy & energy needed
to take away electrons
- more electrons=
denser=lower radius
- trends in
bonding
- elctronegativity difference
dictates how polar it is,
share/take
- metals give away electrons, two
non metals share, two metals
don't react
- all elements want to
have a complete outer
shell
- elctronegativity difference
dictates how polar it is,
share/take
