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
How are the elements arranged?
atomic number

he drew a table and decided to count the number of plants with each trait that turned up he thought it might help him to explain his results
Elements on the left side of the periodic table?
Elements on the left side of the Periodic Table are "Alkali Metals". There is also one non-metal element. H(hydrogen)
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 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 is the second metal in the period table?
Be is the second metal. It is in the second group.
Are group 12 on the periodic table lanthandies or actinides?
No. There are two rows at the bottom of the periodic table. the first row elements are called lanthanides and the second row elements are called actinides.
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.
What are the allowed orbital types for the second period of the periodic table?
The allowed orbital types for the second period of the periodic table are 2s and 2p.
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 are the elements in the second period of the periodic table of elements?
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
Each row in period table is called what?
period
A row across the periodic table is called a?
groupsi
