valence electrons
Each group has a group number.
number of electrons in the bonding shell vary according to the element. for example group 1 in the periodic table contains elements with ony one electron in their bonding shell, similarly group 2 has elements with two electrons in its bonding shell and so on. the group number in the periodic table denotes the number of electrons in the bonding shell of each element present in that particular group
Transition metals
elements in a group have the same number of valence electrons
3rd group
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
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.
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
The family name for group 17 elements in the periodic table is the Halogens.
All elements in a group have same chemical properties. They have same number of valence electrons.
A column in the periodic table is called a group or a family. Elements within the same group share similar chemical properties due to having the same number of valence electrons. There are 18 groups in the periodic table.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
