Theory: This lab focuses on the characteristics and properties of oxides found in period 3 of the periodic table. Naturally, the oxides of different elements have different properties, mainly because of their intermolecular bonds and their intramolecular bonds. Intermolecular bonds refer to the attraction and repulsion found between neighbouring ions or molecules. These typically determine the molecules physical properties, such as boiling/melting points, shape/state, hardness/softness, colour

What causes water to be a polar molecule? Water is a polar molecule because of its polar covalent bonds. In a water molecule, two hydrogen atoms are covalently bonded to one oxygen atom. However, due to the oxygen atom being more electronegative than the hydrogen atoms, the bonds between the oxygen and hydrogen atoms are polar covalent bonds. Since the oxygen atom is more electronegative, the shared electrons between the two different

The 3 types of radiation are Alpha, Beta and Gamma. An Alpha particle (α) is a helium nucleus that is a combination of two protons and two neutrons. This type of radiation is found in heavy elements. The charge of Alpha is positive 2. The mass is 4 atoms. Alpha particle can be stopped by thin paper. The ionizing power for this particle is strong because the charge is positive 2. A Beta particle (β) is a fast moving electron comes from when an unstable neutron breaks down and turns into a proton with

The electronic structure of the doped fullerene interacting with L-Alanine compared to pure fullerene C20 has been calculated with the B3LYP/6-31G basis set. The molecular orbital theory, the chemical reactivity of a molecular system can be estimated using HOMO and LUMO energies and overlaps of molecular orbital [12-14]. In our present investigation the HOMO-LUMO gaps of C19Si-L-Alanine (Si-N) and C20-L-Alanine (C-N) are 2.48768 and 1.81637eV respectively so C19Si-L-Alanine has the more molecular

Linus Pauling was the greatest chemist of the twentieth century – arguably of all time. He was a theoretical physical chemist who became the only person to have won two unshared Nobel Prizes. Growing up in Oregon, Pauling taught himself the fundamentals of chemistry while he was still a teen. His work on chemical bonding marks him as one of the founders of modern quantum chemistry, and his discovery of the alpha helix and beta sheet is a major foundation for the study of protein structure. Although

or liquids that have low melting and boiling points, poor electrical conductors as well as most soluble in non-polar liquids; not in water. Uneven sharing results in the formation of a dipole (the separation of charges between two covalently bonded atoms) referred to as a polar bond with partial ionic charges. Non-polar is equal sharing of electrons, results in the bond between two similar

are in the atom are stored in energy levels called shells. The lowest energy level must be filled first before the electrons can fill the next shell. The first shell can hold two electrons, the second shell can hold up to eight, while the third shell holds a maximum of eighteen electrons. The outermost shell hold what are called valence electrons. When an atom’s outermost shell is complete, it will be stable, while when the shell is incomplete the atom is reactive. To be a stable atom, most elements

through reactions with other elements. However, halogens can be very harmful or deadly to biological organisms. Physical properties of Halogens When the electron shells are filled, the atoms get bigger as you go down the group of halogens. When fluorine is a diatomic molecule, the F-F bond is quite weak (Boundless. “Halogens.” Halogens | Boundless

The electronic configuration of the Mn atom in the allowed ternary compounds, ZnxMn1−xO (x = 0.25, 0.50 and 0.75), is attributed to the Mn2+ [25].

Water has the properties of a polar molecule, meaning that it is imbalanced in its electrons. The hydrogen ions in water are positive and the single oxygen ion is extremely negative. The extremely negative oxygen ion prevails over the positive hydrogen ion, masking the positivity. Like an oxygen ion, the lives of Haitians are negative but others overlook the hydrogen that exist in their experiences. The people of Haiti are similar to water molecules because they face negativity, but unlike a water
