What are elements called that exist in different forms?
If they are in different physical form they are ALLOTROPES. If they are in different atomic form they are ISOTOPES. e.g. Allotropes [ Graphite, diamond and buckyballs* buckminster Fullerene) are allotropes of carbon. They appear different because the arrangment of the atomis is different. Isotopes Carbon 12 , Carbon-13, Carbon-14 are isotopes of carbon , because they have a different number of neutrons in the nucleus.
Which group commonly combines with group 1 elements explain why?
These are elements from the group 17 - halogens; a strong electrostatic attraction exist beween atoms.
Why do elements from group 1 and 7 exist mostly as compounds?
Because
What is a colunm in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
What elements have more than one form?
Carbon has three allotropes, diamond, graphite and buckminsterfullerene.
What elements are different forms of the same element but with different molecular structures?
Allotropes

Do allotropes form salt?
Allotropy is phenomenon only for chemical elements.
Which groups of elements only have 5 elements?
Considering also very heavy artificial elements this group doesn't exist.
Why do elements from group 1 and 7 exist mostly as compounds?
Because
Could a mixture be made up of only elements no compounds?
Only if the element forms allotropes, such as diamond and graphite, which are both allotropes of carbon but can be separated by density.
What is a colunm in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
What elements have more than one form?
Carbon has three allotropes, diamond, graphite and buckminsterfullerene.
What is a neutral group of atoms joined by one or more covalent bonds?
The only group of neutral elements is the noble gases. They are in group 0. They are electronically stable elements that do not tend to react. They exist as single molecules.
A verticle column in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
What are the chemical properties of group 8 elements?
They don't have one. Group 8 is noble gasses.
