1The elements in the far upper right corner are classified as
non-metals
2Elements in group 17 are known as "Safe Former". They are called
Halogens
3valence electrons
Outer Shell -e
4Core electrons
Inner Shell -e
5Main group elements
the non-metals of p-block elements together with the s-block elements
6Transition Metals
D and F, valence e- charge
7Lewis Dot Diagram
Simplified model to show valence e-
8oclet rule
an atom will gain or lose e- to have a full outer shell
9Oxidation State
number of e- an atom needs to gain or lose.
10electron affinity
the energy change an element attracts or holds on to electrons with.
11Electronegativity
A relative measure of electron affinity based on position on the periodic table. (unitless) (to get more)
12Ionization Energy
the energy required to remove the outermost valence electron. (To keep it, how much energy it takes to remove the electron.)
13atomic radious
The distance from the nucleus to the valence shell.
17Why does the electronegativity stop at the Noble Gasses?
The noble gasses are keepers and don't need anymore electrons.
