These five toxic, non-metallic elements make up Group 17 of the periodic table.Fluorine and chlorine are gases. Bromine is one of only two liquid elements. Iodine is a solid. Astatine is radioactive and is one of the rarest of the chemical elements. Alkaline Earth Metals IS made up of six elements.
Goiter is the enlarging of the thyroid gland in the neck. When Iodine is heated, it turns into a purple liquid. Hydrogen is the only elements that aren’t really classified as a group. Hydrogen is at the top of the periodic table because it is the lightest element. 90% of atoms are hydrogen.

Arsenic has 8 Isotopes and Its density is 5.72 g/cm3. Arsenic has a melting point of 817.0 °C, and Its boiling point is 613.0 °C. Arsenic has a rhombohedral crystal structure, and it is usually found in a solid form while on earth. This element is found in group 15, p-block, on the periodic table, and Its period is period 4. Its electron configuration is [Ar] 4s2 3d10 4p3.
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.
AIM To design an investigation to study the kinetics of a reaction of your choice RESEARCH QUESTION With respect to hydrochloric acid (HCl), what is the order of reaction in the reaction between HCl and calcium carbonate (CaCO3) determined by changing the concentration of HCl and measuring the volume of carbon dioxide gas (CO2) collected in 30 seconds whilst keeping the mass of the powdered CaCO3 constant and the temperature of the reaction system at 25oC? BACKGROUND INFORMATION Calcium carbonate (CaCO3) is a chemical compound that is commonly found in rocks such as chalk, limestone, marble and travertine in all parts of the world. It also used as a form of medicine as a dietary supplement for a person with insufficient calcium intake because calcium is needed by the body for healthy bones, muscles, nervous system, and heart. CaCO3 is also used as an antacid to relieve
The specific surface area is between 6.21 and 6.47 m2/g and has a specific gravity of 2.7. Calcium carbonate is prepared through double decomposition of calcium chloride and sodium bicarbonate in an aqueous solution. Density and fineness are governed by the concentrations of the solutions. Calcium carbonate is also obtained from the naturally occurring minerals aragonite, calcite, and vaterite. The particles of calcium carbonate are characterized, finally, by cohesive fluidity.
The inner core is about 759 miles in radius and is composed of iron and nickel metals. The average temperature of the inner core is 9,800 degrees Fahrenheit. The outer core is 1,400 miles thick and is made of iron and nickel fluids. The mantle is the thickest layer. Is composed of a hot, viscous mixture of molten rock that measures 1,800 miles thick.
 Synthesis of the pigment can be summarized as follows: a mixture of quartz, calcium salt, copper salt or copper carbonate (malachite), and flux such as soda or potash are heated at 900–950 C under normal atmospheric conditions for 24 h[12,13] according to the following equation: Figure 1. (a) A general view of the exterior of the temple of Hathor. (b) A plan of the temple. (c) A column representing the well-known shape of
Well if you don’t, i’ll help you out! Bromines atomic mass which is 80 located under it’s symbol which is Br. Every element has to have a family, right!!! Bromines family happens to be group 17 (VIIA) Halogen. And for this specific element the melting poi for Bromine is 19.04°F -7.2°C, and of course there 's a boiling point, which is 137.8°F
- A hydrate is a salt that contains water as a part of its crystal structure. The hydrate used in this lab was Copper (ll) Sulfate Pentahydrate. To heat the hydrate in this lab a crucible is needed. A crucible is a heat resistant container used to heat things to high temperatures. In this lab a mole was used to determine the measurements of all substances.
Copper is essential for all life, but only in small quantities. Copper appears in the periodic table at the top of Group 11 in the 4th period above silver and gold. Copper is one of the most important metals. Specifically, it is a transition metal on the periodic table. Copper is reddish with a bright metallic lustre.
