27/1/2011· Covalent or ionic bonding will determine the type of compound that will be formed. In Chapter 1, we used atomic theory to describe the structure of the fluorine atom. We said that neutral fluorine has nine protons in its nucleus (an atomic nuer of 9), nine electrons surrounding the nucleus (to make it neutral), and the most common isotope has ten neutrons in its nucleus, for a mass nuer …
Covalent Bond - an overview | ScienceDirect Topics
In a single covalent bond, when the electrons are shared between two s orbitals, the resulting bond is a sigma (σ) bond as shown in Figure 3-4.Sigma bonds are the strongest covalent chemical bonds. Sigma bonds also occur when an s and a p orbital share a pair of electrons or when two p orbitals that are parallel to the internuclear axis share a pair of electrons (see Figure 3-4).

Molecular and Ionic Compounds · Chemistry
Compounds are classified as ionic or molecular (covalent) on the basis of the bonds present in them. Ionic Compounds When an element composed of atoms that readily lose electrons (a metal) reacts with an element composed of atoms that readily gain electrons (a nonmetal), a transfer of electrons usually occurs, producing ions.

Is cesium bromide an ionic or covalent compound? | …
Cesium bromide, "CsBr". is an ionic compound, and can further be classified as a salt Usually a bond between a metal and a nonmetal is ionic. Cesium is a metal and bromine is a nonmetal. In addition, we can look at the difference in electronegativity between the two elements. Electronegativity (EN) is the tendency of an atom to attract electrons to itself. Metals tend to have lower ENs than
