noble gases, or inert gases
they are the same thing and they are group 18
they have full valence electrons so they are unlikely to react with other elements

What elements are used to make absolute determinations of the time of formation of materials?
Elements that decay into other elements with a known rate of decay.
How many elements were known in 1860?
In the year 1869, sixty-three elements were known. Out of the 92 naturally-occurring elements, the following were yet to be found:HeliumNeonArgonScandiumGalliumGermaniumKryptonTechnetiumXenonthe Lanthanoids*HafniumRheniumthe Radioactive Elements***With the exception of lanthanum, cerium, and terbium.**With the exception of thorium and uranium.
What is the collective name given to the elements in group vii?
Group 7 elements are known as "halogens".
What are multi atomic elements?
Elements which have two or more different types of atoms are known as multi-atomic elements. eg; HClO4, HNO3 etc.
What it a process in which lighter elements stick together to create heavier elements?
The process in which lighter elements stick together to create heavier elements is known as fusion. This is the process that will be used in the synthesis of a heavier atomic nuclei.
What is chalogen?
It is the16 column of the Periodic Table , so elements inside this column are O , S , Se ,Te , Po
Do all elements on the left group of the periodic table of elements have one outer electron?
That is correct; the first column on the left contains only elements with one electron in their outer shell, also known as "valance electrons". This column is referred to as Group 1, also known as the Alkali Metals.
What is a family or group of elements?
its the elements in a vertical column and they tend to have similar properties (related)
What element has seven electrons on the outer shell?
Halogen elements, which are located in the 17th column of a periodic table that's formally known as "Group 17 (VIIA)". This column of elements consist of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). All of the above elements listed above have 7 electrons in the outer-shell.
What is a group of elements in the periodic table?
A group is a column in the periodic table of elements.
Is there another name for a column of elements?
Columns are also known as Groups or Families. Rows are also known as Periods or Energy levels
What does it mean when elements are on the right of the periodic table of elements?
The Elements on the far right side of the Periodic Table of the Elements are known as the Nobel Gasses.
Number of elements known in the 1800?
36 elements were known in 1800.
What is the location of elements in the periodic table related to?
The layout of the table indicates various properties of the chemical elements using a logical grouping by row and column. The periodic table is laid out so that reading from left to right and top to bottom, each chemical element is listed in the order of atomic number, which is the number of protons in the atomic nucleus of that element. At the top of the table, Hydrogen (H) is element (atomic) number 1, to the right Helium (He) is element number 2, Down one row and from left Lithium (Li) is element number 3 and so on. Thus those elements near the top of the table such as Hydrogen (H) are the lightest and those near the bottom of the table such as Uranium (U) are the heaviest. Elements towards the bottom of the table are more likely to be radioactive. The column structure of the table indicates similar chemical properties for the elements in that column. The first column from the left contains the group known as the Alkali Metals and all of these elements have a single electron in the outermost electron orbit around the atomic nucleus, known as the "outer shell". This electron configuration determines the types of chemical reaction which may occur with these elements. The second column from the left contains the group known as the Alkaline Earth Metals and all these elements have two electrons in the outer shell and hence have similar chemical properties. The column on the far right contains the elements known as the "Noble Gases" that have their outer shell "filled" with electrons and these elements do not generally react chemically with other elements. Thus those elements that appear in any one column will have similar chemical properties to each other and the same type of electron configuration in the outer shell. Most of the elements in the table are metals and appear towards the left and bottom of the table. The non-metal elements are towards the top and right of the table. The area of the table between the metals and non-metals includes the elements known as "semiconductors" such as Silicon (Si) and Germanium (Ge).
Are the majority of all known elements liquids?
No. The majority of known elements are solids. Only two known elements are liquid at room temperature.
How Many elements were known in 1800?
In 1818 there were 49 known and accepted (by the scientific community) elements.
What is a family of an element in the periodic table?
A family of elements (Or Chemical Family) is used to describe a group of related elements. For example, copper, silver, and gold all belong to the same chemical family. These 3 elements are often referred to as the coinage metals. These elements share several common properties.
