Vocabulary 1
Metals
Elements having properties of both metals and non metals
Metalloids
Group that starts with the element Boron
Boron Group
Group that starts with the element Actinium
Actinides
All organic material is made of Carbon and all Carbon materials are organic
True or False
False
All organic material IS made of Carbon, but NOT all Carbon materials are organic.
Metals can be draw into wire because they are
ductile
Usually gasses or solids at room temperature, do not conduct heat or electricity and not shiny
Nonmetals
Group 1 of the periodic table, contains metals that can form salts.
Alkali Metals
Groups that include the lanthanides and actinides, on the bottom of the periodic table but actually fit in between the metals.
Inner Transition Metals
The only metal not a solid at room temperature.
Mercury
An example of a semiconductor which means that it conducts electricity under certain conditions.
Silicon
Element having more than 92 protons which is the atomic number of Uranium
Trans-uranium Element
Group contains the element carbon and silicon which is a semiconductor.
Carbon Group
Group that contains the element Oxygen
Oxygen Group
Elements to the right of the "stair step" line.
metals, non metals, metalloids
Nonmetals
Element whose nucleus breaks down giving off particles and energy.
Radioactive element
Consists of 2 atoms of the SAME element in a covalent bond.
Diatomic molecule
Group 2 on the periodic table, contains both some elements essential for life such as calcium and magnesium, and as well radioactive elements like radium.
Alkaline Earth Metals
Group located next to the Noble gasses, contains reactive elements that tend to bond with other elements such as flourine, chlorine, and bromine.
Halogen Group
These elements often occur in nature as uncombined elements, meaning they can be found in their pure form.
Transition Elements
Forms of the same element that have different molecular structures.
Allotropes
Positively charged metallic ions surrounded by a could of electrons.
Metallic Bonding
Elements in groups 3-12 of the periodic table.
Transition Metals
Group at the far right of the periodic table, all gasses that are stable.
Noble Gases
An allotrope of carbon that can be used as a lubricant.
Graphite
