Atoms
The 3 things are atoms comprised of
What are Protons, Neutrons, & Electrons?
This is the group that Potassium (K) belongs to
What is Alkali Metals?
The charge and name of atoms that lose electrons
What are Cations & they have a positive charge?
This trend is diagonal across the periodic table, with the arrow pointing in the top right hand corner
What is Non-Metallic Character?
Since atoms are neutral, they have the same # of these
What are protons and electrons?
This is the key to chemical behavior
What is Electrons?
*electrons determine chemical behavior*
These are the elements in the Alkaline Earths Group on the periodic table (Name 4 or more)
What are beryllium, magnesium, calcium, selenium, barium, & radium?
The charge and name of atoms that gain electrons
What are Anions & they have a negative charge?
This trend is diagonal across the periodic table, with the arrow pointing in the bottom left hand corner
What is Metallic Character?
There are this many main groups of elements
What is 8?
Mass of one atom
What is atomic mass?
This is the group on the periodic table that does not really want to gain or lose electrons, they are already full
What is Noble Gases?
(or Inert Gases)
This is how an ion's charge is indicated & this is Potassium's charge
superscript & K+
This is the trend of atomic radii
What is decreases top to bottom and right to left of the periodic table?
This essentially contains all of the mass of an atom
What is the nucleus?
The person who discovered Protons
Who was Ernest Rutherford (1919)?
What are Fluorine, Chlorine, Bromine, Iodine, & Astatine?
DOUBLE JEOPARDY!!
This is the crack in Dalton's atomic theory
What is that all atoms of an element do not have the same mass?
This is the trend of ionization energy
What is increases left to right and bottom to top of the periodic table?
This is what you get when you add the # of protons & the # of neutrons together
What is the mass #?
These are the locations of the parts of an atom
What are Protons- in nucleus; Neutrons- in nucleus; Electrons- outside of nucleus?
This section of the periodic table does not follow all of the rules and has multiple oxidation states
What is the Transition Metals?
*Groups 3-12
This is what makes an ion
What is atoms losing or gaining electrons?
This is the trend of Electronegativity (Electron Affinity)
What is it increases left to right and bottom to top of the periodic table?
In general, this is where you can find metals & non-metals on the periodic table
What is metals to the left & non-metals to the right?
