Table Terms
This is a type of element that is typically a hard, shiny solid and is a good conductor of heat and electricity.
Metal
These are the metals that go from groups 3-12 of the Periodic Table and properties of finding valence electrons are different that other elements.
Transition Metals
This is the number of groups in the Periodic Table.
18
This is the symbol For Sodium.
Na
This element is in period 2 and has 6 valence electrons.
O
This is a type of element that is usually a gas or a brittle solid at room temperature, not malleable or ductile and is a poor conductor of heat and electricity.
Non-metal
These are the non-metals in group 18 of the Periodic Table that are not reactive.
Noble Gases
This is the number of periods in the Periodic Table.
7
Give the chemical symbol for
Mercury.
Hg
This element has 3 energy levels and 18 neutrons.
Chlorine
This is a type of element that shares some properties of metals and some of non-metals; located along the Periodic Staircase.
Metalloid
These are the metals in group 1 of the Periodic Table that are the most reactive group of metals. They form a +1 ion.
Alkali Metals
This is what an element's groups determines.
Number of valence electrons and chemical properties
Give the chemical symbol for
Potassium.
K
This metalloid has 6 energy levels.
Polonium (Po)
This is the columns on a Periodic Table that arrange the elements by the number of electrons that are in the outer shell; elements are grouped by their chemical and physical properties.
Group or family
These are the non-metals in group 17 of the Periodic Table that are most reactive group of nonmetals. They form a -1 ion.
Halogens
This is what an element's period determines.
number of energy levels
Forms a -1 ion, used in pools to keep clean, but not Chlorine.
Br
This metal has similar properties to Zinc and its mass is less than or equal to 112 AMUs.
Cadmium
This is the rows in a Periodic Table that separate elements based on their energy levels.
Period
These are the metals in group 2 of the Periodic Table and are most likely to react with group 16 of the Periodic Table. They usually form a +2 ion.
Alkaline Earth Metals
These are the groups that the most reactive elements are located.
1 and 17
This is the main metal used in the filament of light bulbs.
W
This non-metal is similar to Oxygen and has an atomic mass less than Selenium.
Sulfur
