The type of bonding in the given cases has to be identified. Concept introduction: Two main types of chemical bonding exist in chemical compounds. These are, Covalent bond: A type of molecular bonding that deals with the sharing of electron pairs between atoms. Ionic bond: A type of molecular bonding in which two oppositely charged ions are formed by the complete transfer of valence electrons between atoms. The ions in this type of bonding are arranged in a regular way, leading to the formation of bigger molecules. To determine: The type of bonding present in the given diagram.

Solution Summary: The author explains that two main types of chemical bonding exist in chemical compounds: covalent bond and ionic bond.
Definition Definition Connection between particles in a compound. Chemical bonds are the forces that hold the particles of a compound together. The stability of a chemical compound greatly depends on the nature and strength of the chemical bonding present in it. As the strength of the chemical bonding increases the stability of the compound also increases.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
