The elements with similar properties are grouped together in families. They have same number of valence electrons.
by atomic number
Metals are grouped together to the left of the Periodic table.
Hydrogen is not in a group with other families. It actually is in group 1 of the periodic table. It is a diatomic atom when it combines with other elements.
there are no compounds on a periodic table. only elements are placed in the periodic table and they are grouped by similar attributes
Atomic number controls its position in periodic table. It is grouped with the elements having same properties.
the periodic table is grouped according to similarities. when Mendeleev grouped his first periodic table they followed a pattern. any elements that contained similarities they were all put into the same column.
The columns are groups or families, and the rows are periods.
They are grouped by similar characteristics
they are grouped by their chemical properties
It can tell you crtain characteristics of that element.
The periodic table families are called groups. There are 18 groups in periodic table.
Groups or families are the vertical columns on the periodic table. Periods are the horizontal rows on the periodic table.
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
the vertical columns in the periodic table are known as groups or families.
Hydrogen is the first element in the periodic table. There are approximately 118 elements on the periodic table.
families determine the energy level of an element and groups determine their properties.
Oxygen is the eighth element on the periodic table.
The element abbreviated with As on the periodic table is Arsenic
Sodium is the eleventh element on the periodic table.
The second element on the periodic table of elements is helium (He)
