The Different Groups
The number of sections the periodic table is divided into
A compound that is neither a metal, nor is it a nonmetal
Anything to the left of the staircase (formed by Aluminum, Gallium, Indium, Thallium, Tin, Lead, Bismuth, and Polonium), is considered a metal.
Name one of the different subcategories under a non-metal
Reactive Non-metals, and Noble Gasses
The name for a cluster of atoms consisting of protons
the nucleus
Name an example of a section in the periodic table
Alkali, Alkaline Earth Metals, Lanthanide, Actinoids, Transition metals, Post-transition metals, Metalloids, Reactive nonmetals, Noble gasses
An example of a metalloid
Silicone, Boron, Germanium, Arsenic, Antimony, and Tellurium.
Also counts: Selenium, Polonium, and Astatine
Name one of the different subcategories under "metal"
The different subcategories of metals are Alkali Metals, Alkaline Earth Metals, Lanthanide metals, Transition Metals, and Post-Transition Metals
The number of nobel gasses
6
The name for the number of protons
Atomic Number
Name a category that doesn't fit in "metals" or "nonmetals"
Metalloid
Location on the table
The teal in the upper right corner, laddering down.
True or False- the majority of the periods on the table are metals
true
Name one of the 6 noble gasses
Helium, neon, argon, krypton, xenon, or radon
What protons and neutrons are measured in
Amu
Why are the different periods grouped together?
Elements in the same group all have the same number of valence electrons (number of electrons in the outermost shell of electrons in an atom).
The number of metalloids
11
The majority of metals are...
Transition metals.
The number of reactive non-metals
17
The different charges of particles in an atom
Proton= +1
Neutron= -1
Electron= 0
