Atomic Radii and Effective Nuclear Charge03:08

Atomic Radii and Effective Nuclear Charge

58.3K
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

Electronegativity02:54

Electronegativity

76.2K
Whether a bond is nonpolar or polar covalent is determined by a property of the bonding atoms called electronegativity.

Ionic Radii03:10

Ionic Radii

31.4K
Ionic radius is the measure used to describe the size of an ion. A cation always has fewer electrons and the same number of protons as the parent atom; it is smaller than the atom from which it is derived. For example, the covalent radius of an aluminum atom (1s22s22p63s23p1) is 118 pm, whereas the ionic radius of an Al3+ (1s22s22p6) is 68 pm. As electrons are removed from the outer valence shell, the remaining core electrons occupying smaller shells experience a greater effective nuclear...

The Energies of Atomic Orbitals03:21

The Energies of Atomic Orbitals

27.7K
In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.

Electron Affinity03:07

Electron Affinity

39.9K
The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Chemical Bonds02:40

Chemical Bonds

19.7K

Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons...
