These electrons in the outermost orbits determine the chemical behavior of an atom.
valence electrons
These types of elements try to gain electrons in order to reach the ideal configuration.
For low ionization energy - left or right
left
When two nonmetals share valence electrons
covalent bond
Give the orbital valence electrons:
Potassium
4s
Atoms in the same this of the periodic table have the same number of valence electrons.
column, group, or family
Not to be confused with a pet, these types of ions are positively charged.
cation
For high ionization energy - top or bottom
top
In a Lewis structure, the atom with the most of these is depicted in the center.
unpaired electrons
Give the orbital valence electrons:
Chlorine
3p
Most atoms strive to attain this number of valence electrons.
eight
The proper name for Al2S3
Aluminum Sulfide
For high electronegativity - left or right
Right
Name 6 of the 8 elements that exist as homonuclear diatomic molecules.
nitrogen, oxygen, fluorine, chlorine, bromine, iodine, astatine, hydrogen
Give the orbital valence electrons:
Oxygen
2p
This structure shows a representation of valence electrons using dots.
Lewis
Ionic molecules see the lowest possible ratio. What step is missing from from this list?
Drop the + and - from the superscript
use the #s as subscripts
Step 2 - switch the #s
For larger atomic radius - left or right
left
Atoms in this group can NOT have double or triple covalent bonds
7A
Give the orbital valence electrons:
Iron
