some kind of a box
A column is defined as an upright pillar, typically cylindrical and made of stone or concrete, supporting an entablature, arch, or other structure or standing alone as a monument. It can also be a vertical division of a page or text.

∙ 14y agoA column, also known as a family or group, on the Periodic Table represent elements with the same number of valence electrons and the same general properties. Some columns have names such as the Halogens, the Noble Gases, and the Alkali metals and the Alkaline earth metals.

∙ 13y agoThey are primarily used in protein purification. Meaning that you have your target protein but you want to extract it so that it is alone. The columns help the protein to become 'eluted' meaning that they are drawn out of the solution. They need to be because there is tons of 'junk' in this solution (DNA, endotoxins, contaminants, salt, etc.). Different columns are used and they are packed with resins. These resins have specific concentrations of charges (for example think of different concentrations of salt water or such) that help the proteins to become drawn out of the solution. This is done due to charge (ion exchange). I hope this basic answer helps you in understanding the basic role! Cheers

Give the 5 principal of the brnches in chemistry?
The 5 branches of chemistry are the analytical chemistry organic chemistry inorganic chemistry physical chemistry biochemistry
What are specialised branches of chemistry?
There are many specialized branches of chemistry. Some of these branches include biochemistry, physiological chemistry, analytical chemistry, and organic chemistry.
What is the term for the study of chemical substances that contain the element carbon?
Organic Chemistry. For non-carbon containing compounds it is INORGANIC CHemistry For the calculations, equations, physical changes, it is PHYSICAL CHEMISTRY .
What is the Lewis dot structure for SrO?
. Sr .There should be two valence electrons around the element since Strontium is in the second column of the periodic table and has two valence electrons filling the 5s shell.
What branch of chemistry is said to be foundational to the other areas of chemistry?
Organic Chemistry
What is Difference between ODS column and BDS column in column chemistry?
ODS means octadecylsilane and BDS means base deactivated silica.
In what ways are all elements in a given column of the periodic table similar?
chemistry
What are columns in the table called?
groups
What is a family in chemistry?
A family is a vertical column in the periodic table. Elements in a family all share similar characteristics. There are 18 families in the periodic table.
What are families on the priodic table?
In chemistry, a group (also known as a family) is a vertical column in the periodic table of the chemical elements. There are 18 groups in the standard periodic table.
Could you Suggest you some topics for chemistry projects?
The chemistry projects suggestion depends upon student level, at school level the projects may be ,1- electroplating, 2-separation of compounds by column chromatography, 3-preparation of aspirine and other organic compounds.
What is the purpose of an alumina column?
Column chromatography is generally used as a purification technique: it isolates desired compounds from a mixture.Column chromatography is separated into two categories, depending on how the solvent flows down the column. If the solvent is allowed to flow down the column by gravity, or percolation, it is called gravity column chromatography. If the solvent is forced down the column by positive air pressure, it is called flash chromatography, a "state of the art" method currently used in organic chemistry research laboratories The term "flash chromatography" was coined by Professor W. Clark Still because it can be done in a "flash."
When Excel is installed the default chart type for a PowerPoint slide is what chart?

How does chemistry depend on chemistry?
Chemistry is entirely dependent on chemistry. If it weren't for chemistry, chemistry wouldn't exist.
When you insert a column where does it automatically go?
The column will go where the currently selected column is, pushing all columns to the right. So if column D was selected and you inserted a column, column D would become column E and the inserted column would now be column D.The column will go where the currently selected column is, pushing all columns to the right.

What are the five major branches of chemistry?
there are five branches: inorganic, organic, analytical, physical, and biochemistry. they could be further broken down into sub-branches such as organometallic chemistry, physical organic chemistry, electroanalytical chemistry, and so on and so forth.
