Question

Answer

For example

He li na ki rb se fariyad .

They have one Electron in last shell (I.e. same electronic configuration).

Beta Maange Car Scooter Baaap Razi .

2 electrons in last shell .

And so on ....

Answer

The

periodic table

also

has

a special name for its

vertical

columns. Each column is called a

group

. The

elements

in each

group have

the

same

number of electrons in the outer orbital. Those outer electrons are also called valence electrons.

Answer

Elements in the same vertical group of the Modern Periodic Table have the same:

Electronic configuration of outermost shell

Explanation:

The Modern Periodic Table is organized based on the electronic configuration of the elements. Each element is arranged in order of increasing atomic number, and elements with similar properties are grouped together in the same vertical column, known as a group or family.

Atomic Number:
The atomic number of an element represents the number of protons in its nucleus. In a vertical group, the atomic number of elements increases from top to bottom. Therefore, elements in the same group do not have the same atomic number.

Number of Protons:
The number of protons in an atom determines the element's identity. As the atomic number increases in a group, the number of protons also increases. Hence, elements in the same group do not have the same number of protons.

Number of Electrons:
The number of electrons in an atom is equal to the number of protons in a neutral atom. Elements in the same group have similar chemical properties because they have the same number of electrons in their outermost shell, also known as the valence shell. However, elements in the same group may have different total numbers of electrons due to differences in atomic number.

Electronic Configuration of Outermost Shell:
The electronic configuration refers to the arrangement of electrons in the energy levels or shells of an atom. Elements in the same group have similar electronic configurations of their outermost shell. The outermost shell is particularly important in determining an element's chemical behavior and reactivity. Therefore, elements in the same group exhibit similar chemical properties due to their common electronic configuration.

In summary, while elements in the same vertical group of the Modern Periodic Table have different atomic numbers, numbers of protons, and numbers of electrons, they do have the same electronic configuration of their outermost shell. This similarity in electronic configuration is responsible for their similar chemical properties.
