What is a group in a periodic table?
group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts.
Where is the group on a periodic table?
Groups: The vertical column of the periodic table that signifies the number of valence electrons in an element. Periods: The horizontal rows in the periodic table that signify the number of electron shells in an element. Families: Elements that have the same number of valence electrons and therefore similar properties.
What group means?
Each group in the Periodic Table signifies identical outer shell electronic configuration for the elements constituting that group. For example,each element of group 1 has one electron on its outermost shell. Was this answer helpful?
What is group and period in periodic table?
The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
How do you find the group and period of an element?
To determine the group, we need to understand some rules:
- If the element is in s block, then the group number is equal to the number of valence electrons.
- If the element is in the p block, then the number of the group can be determined by the formula: (number of valence electrons + 10).for groups.

What is group period?
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What is group and period?
Why are there groups in the periodic table?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
