Why are the elements grouped together in periods and groups?
Because they are!
How are elements grouped into periods?
there are grouped in clomesand rows ad groups
How many groups or columns are in the periodic table?
Omitting the f-block elements, there are 18 groups in the periodic table. Groups 1 and 2 contain s-block elements. Groups 3-12 contain d-block elements and groups 13-18 are made out of p-block elements. The only exception is helium is named under group 18, being a noble gas.
The modern periodic table elements are arranged?
The modern periodic table arranges elements based on their atomic number, which is the number of protons in the nucleus. Elements with similar chemical properties are grouped together in columns called groups or families. The table is divided into periods (rows) that indicate the number of electron shells in an atom.
What elements can be classified by arranging them it groups?
they are grouped by there collums
How elements are grouped in columns in the periodic table?
There are 18 groups in the Periodic Table of elements.
Why are most of the nonmetals found in the periodic tables?
Non metals are grouped together because of their similar properties. They are placed in groups-15,16 and 17
How are the elements grouped?
Literal groups are by similar chemical properties (alkaline earth, halogens, etc.). Elements are arranged by atomic number (number of protons) and are grouped also by their state of matter. For example, metals are in the middle, liquids are grouped together, and except for Helium, gases are as well.
Why is bromine classified in that group 17?
Because all of the elements in the groups or families all have similar qualities. For example, all of the elements in the noble gas family are grouped together because they are stable elements.
Why are non metals grouped together?
Non metals are grouped together because of their similar properties. They are placed in groups-15,16 and 17
Why are the non-metals grouped together?
Non metals are grouped together because of their similar properties. They are placed in groups-15,16 and 17
In the modern periodic table the elements are arranged according to their?
In the modern periodic table, elements are arranged according to their atomic number, which represents the number of protons in an atom's nucleus. This arrangement allows elements with similar chemical properties to be grouped together in columns called groups or families. The periodic table is organized into periods (rows) and groups (columns) based on this atomic number.
