Different types of bonds/interactions in proteins lead to different kinds of structures. Three of the most commonly known chemical bonds in proteins include the hydrogen bond, the covalent bond, and the ionic bond. In hydrogen bonds, hydrogen interacts with oxygen, nitrogen, or fluorine to form either the alpha helix, or the beta sheet, which in turn determines its secondary, tertiary, or quaternary structure. Another type of bonds, the covalent bond, links amino acids together by sharing electrons;

5. The two primary types of chemical bonding is ionic and covalent. Ionic bonding is when atoms give

The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.

An ionic bond is a bond that results from the attraction between oppositely charges ions; one atom "gives" another atom an electron. Combinations of metals and nonmetals typically form ionic bonds. A covalent bond is a bond that results from

A covalent bond is a bond that occurs when atoms in a molecule share a pair of electrons. For example, “the atoms in sugar do not form ions; instead, they are held together because of shared electrons.”

When analyzing the IR spectrum of Ruthenium complex with DMSO, the prominent peak is presented at 1105.54 cm−1. This peak indicates that S=O bonded in DMSO. For DMSO, the frequency is around 1050 cm−1. From our spectra obtained for DMSO where the S=O peak is at 1017.65 cm−1. Since the bond appears at a higher frequency, this shows that the bond is strengthened by the reaction. This indicates that when the copper metal was combined with DMSO, it bonded with the Sulfur atom. Combining ruthenium with sulfur atom caused it to donate a pi electron as a back donation.

-Covalent bond- Electrons are shared between two atoms, neither atom completely gains or loses electrons. Between two nonmetals.

To discuss different types of chemical bonding in different substances (precursor to the next lesson topic)

Before the atoms are bonded, the single, non-bonded pairs of electrons are called lone pairs of electrons. When the atoms combine by means of covalent bonding they form molecules. Simple covalent compounds consist of many small molecules. The covalent bonds within the molecules are strong but the bondings between them to form the compounds are relatively weak, the force that occurs between them is called the intermolecular force.

To achieve this, the Heaven Lab uses computational chemistry and laser spectroscopy. For computational chemistry, they use ECP (Effective Core Potential) to correct the mass of the electron and the Darwin term for the actinide elements; following the theories of configuration interaction, density functional theory, and active space methods. Also, Thorium oxide (a specific actinide detectable through spectroscopy) has been tested using laser ablation of an actinide rod with Laser induced fluorescence, REMPI, PFI, PFI-ZEKE, and MCP. Ultimately, they have found that computational chemistry and laser spectroscopy are significant tools in identifying bonding properties of
