Periodic Table Concepts
inner transition metals
- the elements on the two rows which appearunderneath the main body of the periodictable
- These elements are very reactive and very unstable.Often these elements can only be made in alaboratory and they they usually have radioactiveproperties
- Some examples of this are Cerium, Dysprosium,Erbium, Europium, Gadolinium, Holmium,Lutetium
- The two scientists who had the biggestimpact were Dmitri Mendeleev and LotharMeyer.
- Mendeleev arranged the elements in hisperiodic table in order of increasing atomicmass
- Meyer used atomic weights to arrange 28elements into 6 families that bore similar chemicaland physical characteristics, leaving a blank foran
- example: every element in a group has the samenumber of valance electrons, and each element willhave a larger mass and number than the elementbefore it.
- basically it states that elements follow apattern which controls theircharacteristics
- This is the principle that states that properties ofthe elements recur periodically as their atomicnumber increases.
- elements can be classifies by their mass, numberof protons, number of neutrons, and commoncharacteristics
- classes can be separated by the number ofvalance electrons that they have, this effects theircharacteristics
- classifications include number of valanceelectrons, types of groups and periods, and atomic numbers
- Non-metallic elements
- Solid Halogens: Astatine and Iodine
- Liquid Halogens: Bromine
- Gas: Fluorine and Chlorine
alkaline earth metals
- They are reactive, electropositive, divalent metals,and form basic oxides that react with water toform comparatively insoluble hydroxides.
- This is are the second group
- beryllium, magnesium, calcium,strontium, barium, and radium
- They are found on group one, which isthe far left column on the periodictable.
- They are very reactive, electropositive,monovalent metals forming strongly alkalinehydroxides.
- Some of which include sodium,potassium, rubidium, cesium, andfrancium
- They were long believed to be totally unreactivebut compounds of xenon, krypton, and radon arenow known.
- They are the the farthest mostright group on the periodic table.
- Some noble gases include helium,neon, argon, krypton, xenon, andradon
- there are many different transitions metals butsome examples are iron, manganese, chromium,and copper.
- These metals take up multiple groups on theperiodic table and can be found in columns 4through 12.
- Chemically they show variable valence and astrong tendency to form coordination compounds,and many of their compounds are colored.
