Let's get energized
These electrons in the outermost orbits determine the chemical behavior of an atom.
What are the valence electrons?
These types of elements try to gain electrons in order to reach the ideal configuration.
What are the nonmetals?
The amount of energy needed to take an electron away from an atom.
What is ionization energy?
A shared pair of valence electrons that holds atoms together.
What is a covalent bond?
Al2S3
What is alunimun sulfide?
Atoms in the same this of the periodic table have the same number of valence electrons.
What is column?
Not to be confused with a pet, these types of ions are positively charged.
What are cations?
What is increases?
In a Lewis structure, the atom with the most of these is depicted in the center.
What is unpaired electrons?
Fe3N
What is iron (I) nitride
Most atoms strive to attain this number of valence electrons.
What is eight?
The proper name for Al2S3
What is aluminum sulfide?
This is a measure of how strongly an atom attracts extra electrons to itself.
What is electronegativity?
Molecules made up of two atoms which are the same type.
What are homonuclear diatomics?
MgO
What is magnesium oxide?
This structure shows a representation of valence electrons using dots.
What is Lewis structure?
Ionic molecules seek the lowest possible ratio. What step is missing from this list?
-Drop the + and - from the superscript.
-use the numbers as subscripts.
What is step 2 - switch the numbers?
This is an indicator of an atom's size.
What is atomic radius?
Atoms in this group can NOT have double or triple covalent bonds.
What is group 7A?
Cr2O3
What is chromium (III) oxide?
When forming an atom's Lewis structure, dots are placed in this direction around the symbol beginning on the right side.
What is clockwise?
Exceptions to ions of atoms will always be given this to signify the positive charge on the metal.
What are roman numerals?
In general, the atomic radius does this from left to right on the periodic table.
What is decreases?
Names of the elements that make up homonuclear diatomiocs.
What are Hydropgen, Oxygen, Nitrogen, Chlorine, Bromine, Iodine, Fluorine, Astatine?
The names of the elements that protect the earth from the harmful rays of the sun.
What are nitrogen, oxygen, and ozone.
