Atomic Structure

Atomic structure.

Structure of the Atom➖By 1900, it was discovered that the atom was not a simple, indivisible particle, but rather it contains sub-atomic particles.➖J.J. Thomson discovered the sub-atomic particle n...

Calculate the atomic number and number of p-electrons of an atom whose valance shell electronic configuration is 4s?

The electron whose valence shell electronic configuration 4s² may be Calcium(Ca). The atomic number of calcium is 20. The electronic configuration of calcium is

Ca₂₀ = 1s², 2s² 2p⁶, 3s² 3p⁶, 4s²

The total number of p-electrons are 12.

Bohr's Atomic Theory

In 1913, Danish scientist Neils Bohr proposed a model of the atom which was based upon Planck's quantum theory of radiation.The basic postulates of Bohr's theory are:An atom consists of a small hea...

Rutherford's Atomic Model (Scattering Experiment)

In order to understand the arrangement of electrons and protons in an atom, Rutherford and his coworkers performed a series of experiments known as Rutherford's scattering experiments. They bombard...

1. Name the type of bonds which are present in ice. 2. Explain O-hydroxy Benz aldehyde and P-hydroxy Benz aldehyde, which is more soluble in water and why?3. Lone pairs of electrons p...

1. Name the type of bonds which are present in ice.

Ans: The type of bond present in ice are: 1. Covalent bond 2. Hydrogen bond

2. Explain O-hydroxy Benz aldehyde and P-hydroxy Benz aldehyde, which is more soluble in water and why?

Ans: P-hydroxy benzaldehyde is more soluble in water than o-Hydroxy benzaldehyde, because P-Hydroxy benzaldehyde can form hydrogen bonds with water molecules resulting in enhanced solubility.

3. Lone...

Draw the orbit structure of Ethyne

Each carbon has two half-filled orbitals in ground state (1s², 2s², 2p_x ¹ 2p_y ¹, 2p_z ⁰). It has four unpaired

electrons in excited state since one electron is promoted from 2s to empty 2p orbital during chemical reaction

(1s², 2s², 2p_x ¹ 2p_y ¹, 2p_z ⁰).. i. e.

Now, one 2s and one 2p orbitals undergo sp hybridization to form two sp hybrid orbitals of equivalent energy and identical shape and size which take linear geometry with bond angle 180º....
