Elements that are in the same horizontal (left to right) rows, have similar outer shells.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
The groups on the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
The periodic table is a set of elements organized by their atomic number, electron configurations, and recurring chemical properties. It consists of rows, known as periods, and columns, known as groups. Elements in the same group share similar chemical behaviors.
They are the same
They have the same Valency
they have the same number of outer electrons
they all have the same electrons.
Their valence electrons are in the same energy level.
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Elements in a given group have the same number of valence electrons and hence they have similar properties.
They all have the same number of core electrons
they all have the same number of core electrons
