Question

Define Electronic configuration and valence shell electronic configuration.
.I also nice to meet you .​

Answer 1

Answer:

$\huge\bold\blue{Electronic Configuration:}$

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.

$\huge\mathcal{\fcolorbox{purple}{pink}{\blue{Valence Shell Electronic Configuration}}}$

The highest occupied electron shell is called the valence shell, and the electrons occupying this shell are called valence electrons. The chemical properties of the elements reflect their electron configurations. For example, helium, neon and argon are exceptionally stable and unreactive monoatomic gases.

Answer 2

Answer:

Electronic Configuration;

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.

Valence Shell Configuration;

The highest occupied electron shell is called the valence shell, and the electrons occupying this shell are called valence electrons. The chemical properties of the elements reflect their electron configurations.

For example, helium, neon and argon are exceptionally stable and unreactive monoatomic gases.
