As mentioned in answer to question to 2b, ionic compounds have free mobile ions for conduction of electricity only in the molten state and in aqueous state. Hence, given substance is most likely to be ionic as it exhibits conductance only in these states. In addition to that, it has high melting point, which is characteristic of ionic compounds.  4) A lustrous grey – white solid melts at 1650°C. It is electrically conductive as both a solid and a liquid, but not soluble in either water or any organic solvent.
Titanium is soluble in concentrated acids and it is able to rust. However, Phosphorus is soluble in Phosphorus Disulfide and is not able to rust. Not only do they differ at these properties, but they also have different atomic radii, electronegativity, and electron configuration. On one hand, Titanium’s atomic radius, or the size of its atom is 215 pm. Its electronegativity, or the “... measure of the tendency of an atom to attract a bonding pair of electrons,” (Clark Jim, 2013), is 1.54.
These metals have only one electron in their outer shell. This means they are ready to lose that one electron in ionic bonding with other elements. As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Cesium and francium are the most reactive elements in this group.
The literature melting point range of methyl trans-cinnamate is ~34-38oC (Aldrich).4 The obtained melting point of the crude was 34.5-35.5oC, which is a highly narrow range of less than 1oC difference and it also falls within the expected melting point range. Hence, the crystal lattice structure of the product is largely intact, requiring an even amount of thermal energy to melt the sample. The experimental melting point range indicates the crude product is relatively pure with minimal impurities. The percent yield was satisfactory, having a 68% yield. To optimize this yield, consider the steps in how the reagents are introduced to the reaction mixture in terms.
Sulphur is a yellowish, non-metallic chemical element in the periodic table. It is found in group 6 and period 3. Sulphur is identified by the letter S. Since Sulphur is the 16th Element of the periodic table therefore atomic number is always similar as the proton number which is located in the nucleus and converts the nucleus in to a positive charge as neutron is a neutral charge (+-) so positive (+) plus neutral (+-) equals a positive charge. The atomic mass for sulphur is 32 amu or (Atomic Mass Unit is the international system of units). The melting point of sulphur is 112.8 °C and the boiling point of Sulphur is 444.6 °C.
The letter A stands for atomic properties of Arsenic. Arsenic’s atomic number is 33, and Its atomic mass is 74.9216amu. Arsenic is a metalloid, which means it has properties of both nonmetals and metals. This element is also a semiconductor. Arsenic has 8 Isotopes and Its density is 5.72 g/cm3.
The concentration of twist-boat conformation at room temperature is very low (less than 0.1%) but at 1073 Kelvins it can reach 30%. Rapid cooling from 1073 K to 40 K will freeze in a large concentration of twist-boat conformation, which will then slowly convert to chair conformation upon heating. The half-chair conformation is a transition state with C2 symmetry generally considered to be on the pathway between chair as well as twist-boat. It involves rotating one of the dihedrals to zero such that four adjacent atoms are coplanar and the other two atoms are out of
Halogens are group 17. Halogens are highly reactive in elemental form. Even though this group only needs one electron in its outer level, it has seven electrons. When halogens are in gas form they are diatomic molecules. Diatomic molecules are two atoms in the same covalent bonds.
The larger the amount of unstable atoms, the larger the probability of a number of these atoms deterioration. The rate of decay, is the rate at which the radiation is released . Particles will continue emitting radioactive decay until the atom becomes stable again. When they becomes stable, it is no longer the same element. The particles has changed.
Electrical resistance related to the ability of the substance conduct electricity. Resistivity measured by ohmmeter classifies compound with under 2000 ohms as good conductors, which are usually aqueous ionic and solid metallic, between 2000-20,000 ohms as weak conductors, and above 20,000 ohms are non-conducting such as
