How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
What are table leaves?
Some tables can be extended by pulling at both ends of the table to open up a space in the middle of the table, then inserting another piece of table top. This piece you insert is called a table leaf. If you have a table that can hold a few of them, they are called table leaves.
What are the verticle colums in the periodic table called?
The vertical columns are called groups; at one time it was common to use Roman numerals to describe the groups of elements, but now the preferred usage is standard numbers.The groups also have names, in some cases for individual groups and in other cases for a block of groups.Group 1 is called the Alkali Metals, the most active metalsGroup 2 is called the Alkaline Earth MetalsGroups 3-12 are called the Transition Metals, and include some of our most useful metallic elements.Groups 13-16 are the PMN Elements (Post-Transition Metals, Metalloids and Non-metals - metals are near the bottom, non-metals are near the top - a complex block)Group 17 is the Halogens, the most active non-metalsGroup 18 is the Noble Gases, the least active non-metalsThe two rows of elements usually displayed at the very bottom of a periodic table are called the Lanthanides and Actinides, and they fit into the periodic table between Group2 and Group 3. So we might call the Lanthanides and Actinides Group 2.5
Sucrose is made up of one glucose molecule and one fructose molecule For this reason it is called a?
If a sugar is composed of two monomers, it is called a disaccharide.
The illustrated arrangement of the elements and their atomic properties is summarized in the?
Periodic Table
What is second period at the bottom of the periodic table called?
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
What is the period at the bottom of the table called?
Actinides
What are the first three periods of the periodic table called?
The first three periods of the periodic table are called the first period, second period, and third period.
What is oxygens period?
Oxygen's period on the periodic table is the second period.
What is the second period called on the bottom of the periodic table?
There are no specific names for rows in the periodic table because properties of elements in the rows do not match with one other. If we talk about the groups, then there is always some kind of similarity in the groups. For instance, let us take group-I, they are known as the "Alkali metals" because all of them form alkali solutions when their oxides are dissolved in water.
What element is in the halogen family and in the second period of the periodic table?
Fluorine is in the halogen family and in the second period of the periodic table.
What is the second metal in the period table?
Be is the second metal. It is in the second group.
What is the second period on the periodic table called?
Second period elements have two electronic shell.It comprises of eight elements.They are lithium,beryllium,boron,carbon,nitrogen,oxygen,fluorine and neon.
What is the name of the rows of the periodic table?
The horizontal rows on the Periodic Table are called periods, while the vertical columns are called groups or families. For instance, iodine is in the same group, but different period to fluorine, chlorine and bromine.
A horizontal row of elements on the periodic table is called?
The horizontal rows of the periodic table are called Periods and the vertical rows are called groups.
Each row in period table is called what?
period
A row across the periodic table is called a?
groupsi
