Dmitri Mendeleev (in his Periodic Table, who arranged according to increasing Atomic Mass).
Niels Bohr in the modern periodic table, where the elements are arranged in increasing atomic number.
What else can I help you with?
WHY did Mendeleev arrange the elements in periods?
he put them in groups to show acids from alkali's and gasses from metals
What group on the periodic table contains the fewest elements?
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
Which groups compose the mains group elements?
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
How many groups columns are in the periodic table of elements?
There are 18 groups in the periodic table of elements.
Which groups make up the transitional metals?
Groups 3-12
How many groups can the elements be put?
The elements are grouped in to 7's. I took John Newlands 12 years to think of that solution. :)
How many groups of elements in periodic table?
There are 18 groups and 7 periods in the modern periodic table.
Mendeleev's name for a column of elements?
mendeleev's name for a column of elements was groups.
WHY did Mendeleev arrange the elements in periods?
he put them in groups to show acids from alkali's and gasses from metals
How many groups of elements we're formed?
5 groups of elements
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
Why are group 8 elements very few?
The arrangement of chemical elements in groups and periods is determined by the periodicity of the chemical properties. In the case of the transition state elements, there are some smaller groups because of the way the incomplete inner electron shells are filled.
The vertical columns on the periodic table of elements are called periods. true or false?
no its false i put true and it was wrong they are called groups!!!!!
Why do the elements belong in their groups?
because they have similar properties to the other elements in their groups
What group on the periodic table contains the fewest elements?
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
What are elements in a column called?
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
Why are elements grouped in the periodic table?
I am assuming you mean to ask why elements go into specific groups Elements that have the same number of valence electrons are put into the same group. Because they all have the same number of valence electrons, it could also be said that elements are put into groups based on their chemical properties.
