Investigating An Element's Group In The Periodic Table

7. The more-electronegative element in a binary compound is assigned the number equal to the charge it would have if it were an ion.

* Plants can remove metals from low grade ores. The metal can be recovered by processing the ash from burning the plants.

Isotopes are different forms of the same element. They have the same number of protons and electrons, but are different in the number of neutrons. As an example, consider the three isotopes of Candium. M&Ms, Skittles, and Reese's Pieces. They are all types of Candium with only one proton in the nucleus and one electron in an energy level around the nucleus, but all three have different numbers of neutrons in their nuclei.

8. To some observers, the mineral shown in Figure 1.6 (p. 5 lab book) exhibits a metallic luster, while others describe its luster as nonmetallic. Based on the streak of this sample, how would you describe its luster? Luster: nonmetallic

Due to these factors, this graduate student supplies a rating of ‘3’ concerning this element.

Copper is formed by the melting and cooling of molten rock and found fairly close to the Earths’ surface, alongside with silver it has sulphite within the ores as they are created in brine which is a boiling salty water deep within the Earths’ crust and then pushed up through ocean vents and create a chimney like effect. Gold is formed through Hydrothermal-hot water-fluids of which are extremely rich in sulphur and found generally near or in

These different elements

1. Decide if the mineral is metallic or non-metallic based on its luster and streak.

It is necessary to identify the identity of two unknown metals. This is important because a metal scrap yard must know the identities of the metals before they can be recycled. It is also necessary to know what each metal is if a building is to be made using one or more of these metals. Identifying the metals will be done using intensive properties. Intensive properties do not depend on the amount of material present. Density is an intensive property found with the formula D=m/v. Which is defined as mass divided by volume to find the density.

I chose Na, Si, C because the atomic radius shrinks as you go down the row or group and then up a period. The atomic radius decreases as you go across because a proton is added down the row, increasing positive charge therefore, attracting electrons closer to the nucleus.

Sodium Symbol: Na Diagram: Atomic mass: 11 Atomic number: 22.990 Bohr atomic model: We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass. It is soft enough to be cut with a knife.

Metals are chemical components with general characteristics and similar Physical and Chemical Properties underneath traditional conditions. The study of metals is named science.

Out of many minerals in which a metal may be found, only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena, PbS, etc.

Some facts about metals are that they are generally ductile, meaning that they can be hammered thin or drawn into wires. Metals can also be liquified by heating and then resolidified by cooling. Presently metals are the strongest building materials in common use. Found in nature, metals come in the form of oxide ores, meaning they are a compound of oxygen mixed with a mineral containing a valuable constituent such as metal. Metals can also corrode and wear away by oxidation.
