Question

variation of electronic configuration in groups​

Answer 1

Answer:

The electronic configuration of an atom is the numerical representation of the arrangement of electrons distributed in the orbitals of the atom. This determines the position of an element in the periodic table and in turn its chemical behavior. It explains how the atoms are held together by the chemical bonds, and the peculiar trends which are observed in the rows and columns of the periodic table. In this article, we will discuss the electronic configuration of elements in the same periods and groups of the periodic table.

Answer 2

Answer:

• As we traverse down a group the electronic configuration in groups changes hugely.
• A new subshell is added to the elements as we traverse down a group.
• All the elements in a group have similar properties and also have the same valency
• Electron configuration can be described as how electrons are assembled within the orbitals shells and subshells of an atom.
• It is important to understand what an electron is in order to fully understand the electron configuration.
• An electron is a sub atomic particle that is associated with a negative charge. Electrons are found outside of the nucleus, as opposed to neutrons (particles with neutral charge,) and protons (particles with positive charge.)
• Furthermore, electrons are associated with energy, more specifically quantum energy, and exemplify wave-like and particle-like characteristics.
• The word configuration simply means the arrangement of something.
• Therefore electron configuration in straightforward language means the arrangement of electrons.
