Valency valence electrons

A formal charge is a charge associated with an atom that does not exhibit the expected number of valence electrons. When calculating the formal charge on an atom, we first need to know the number of valence electrons the atom is supposed to have. We can get this number by inspecting the periodic table, since each column of the periodic table indicates the number of expected valence electrons (valence electrons are the electrons in the valence shell, or the outermost shell of electrons— you probably remember this from high school chemistry). For example, carbon is in Column 4A, and therefore has four valence electrons. Now you know how to determine how many electrons the atom is supposed to have. [Pg.10]

Know the meaning of nucleus, electrons, protons, neutrons, atomic number, atomic weight, shells, orbitals, valence electrons, valence, kernel. [Pg.2]

Valence-bond theory A theory of bonding that states that bonds form through the spatial overlap of orbitals containing valence electrons. Valence-bond theory is consistent with the geometric predictions of VSEPR theory. [Pg.3]

Formal charge = valence electrons - valence electrons in free atom j in bound atom... [Pg.43]

Electrons related to the atom s highest principal energy level are referred to as valence electrons. Valence electrons determine the chemical properhes of an element. [Pg.145]

Gaussians were originally introduced because they were easier to deal with mathematically than other functions that fitted the orbitals more accurately. They continue to be used because a good approximation to orbitals can be obtained from a reasonably small set. Orbitals of valence electrons (valence orbitals) are often well described by three to five Gaussians. Different sized basis sets containing different numbers of Gaussians are available and can be chosen to suit the problem you want to solve. [Pg.34]

Recall that the group number gives the total number of valence electrons. For example, all Group 6 elements have six valence electrons (valence configuration ns np" ). [Pg.415]

Similarly, all Group 7 elements have seven valence electrons (valence configuration ns np ). [Pg.415]

Next we want to develop some general procedures for writing Lewis structures for molecules. Remember that Lewis structures involve only the valence electrons of atoms, so before we proceed, we will review the relationship of an element s position on the periodic table to the number of valence electrons it has. Recall that the group number gives the total number of valence electrons. For example, all Group 6 elements have six valence electrons (valence configuration ns np ). [Pg.371]

This qualitative model for the chemical bond describes molecular structure with localized valence electrons. Valence electrons repel each other strongly when they are close to each other in the same shell on one atom and have the same spin. The Linnett model for the bond is based on the recognition that electron correlation exists, which means that the position or the path of a valence electron strongly depends on the positions of the other valence electrons. [Pg.68]

These electron configurations show that some similarities among each group of elements are in terms of their valence electrons. Valence electrons are the s and p electrons in the outermost energy level of an atom (see Chapter 3). [Pg.63]

Each principal energy level is subdivided into regions of space called orbitals. The valence shell is the outermost occupied shell, and it contains the valence electrons. Valence electrons are important because they take part in chemical bonding. [Pg.86]

The metal consists of positive sodium ions in a "sea" of valence electrons.Valence (bonding) electrons are free to move throughout the metal crystal (beige area). [Pg.352]

Chemical compounds form because electrons are lost, gained, or shared between atoms. The electrons that interact in this manner are those in the highest energy levels. These are the electrons most subject to the influence of nearby atoms or ions. The electrons available to be lost, gained, or shared in the formation of chemical compounds are referred to as valence electrons. Valence electrons are often located in incompletely filled main-energy levels. For example, the electron lost from the 3s sublevel of Na to form Na+ is a valence electron. [Pg.152]
