Which two blocks of the periodic table make up the main - group elements?
Main group elements include elements (except hydrogen) in groups 1 and 2 (s-block), and groups 13 to 18 (p-block).
Why are the main block elements also called the representative elements?
The representative elements are in the groups 1,2, 13-18; the name is given to make a difference toward transition metals.
What are elements in groups 3-12 on periodic table?
They make up the d-block and are the transition elements.
What are the two main groups?
There are eight groups that make up the main group elements. They are groups 1, 2, and 13 - 18. They are also called the representative elements.
Which groups make up the transitional metals?
Groups 3-12
What is s block in the periodic table?
The s-block in the periodic table consists of groups 1 and 2, which include elements that have their outermost electrons in the s orbital. These elements are typically metals and have similar chemical properties due to the configuration of their outermost electrons. The s-block elements are known for being reactive, easily forming positive ions by losing electrons.
What groups make up the d block?
3-12
Which of the elements are representative elements in the periodic table?
All of them. "Representative elements" means "representative of the group". A group which doesn't have any representative elements would be a largely meaningless group.Group-1, 2,13-18 include representative elements. Group-1 and 2 contain metals. Group 13-17 contain non metals. Group18 comprises of noble gases.
What is the relationship between cells and molecules?
Atoms make up elements. groups of elements make up molecules. Groups of molecules form macromolecules (polymers) which make up cells.
What three main elements make organisms?
Carbon, hydrogen, and oxygen are the three main elements that make up living things.
Which two groups were taken out of the periodic table in order to make it smaller?
If you mean what I believe you mean, they weren't "taken out", they were just moved. The lanthanides and the actinides ... the series of 15 elements starting with lanthanum and actinium respectively ... are often shown below the table to make it narrower horizontally (sometimes the makers of the table insert a "placeholder" where lutetium and lawrencium, the last elements in the series, should properly go; these elements are generally considered part of their respective series despite being d-block elements rather than f-block elements).
How would you descibe the arrangement of the periodic table?
The two main arrangements of the periodic table are the groups, which form the columns of the table, and the periods, which form the rows. There are some similarities between elements in the same period, but most similarities are shared within the groups of elements.
