Using the following information, classify each element tested as a metal, nonmetal, or metalloid. Metals have a luster, are malleable, and conduct electricity. Many metals react with acids. Nonmetals are usually dull in appearance, are brittle, and do not conduct electricity. Metalloids have some properties of both metals and nonmetals. a. b.

metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light. Approximately three-quarters of all known chemical elements are metals. The most abundant varieties in the Earth's crust are aluminum, iron, calcium, sodium, potassium, and magnesium. The vast majority of …

Element Symbol: Hg Atomic Number: 80 Atomic Weight: 200.592 Classification: Transition Metal or Post-Transition Metal State of Matter: Liquid Name Origin: The symbol Hg comes from the name hydrargyrum, which means "water-silver." The name mercury comes from the Roman god Mercury, known for his swiftness.

Uses. Most indium is used to make indium tin oxide (ITO), which is an important part of touch screens, flatscreen TVs and solar panels. This is because it conducts electricity, bonds strongly to glass and is transparent. Indium nitride, phosphide and antimonide are semiconductors used in transistors and microchips.

The elements of Group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium. Alkaline earth metals also react with oxygen, though not as rapidly as Group 1 metals; these reactions also require heating. Similarly to Group 1 oxides, most group 2 oxides and hydroxides are only slightly soluble in water and form basic, or ...

Most common metals are nonferrous, including lead, aluminum, nickel, copper, brass, titanium, and zinc. 3 File a section of the metal to gauge its hardness. Run a carbon steel file over an inconspicuous part of your sample. If the file slides easily over the surface of the metal, it means that it's too hard for the file to leave a mark.

Certain elemental properties become apparent in a survey of the periodic table as a whole. Every element can be classified as either a metal, a nonmetal, or a metalloid (or semi metal), as shown in Figure 3.8.2. A metal is a substance that is shiny, typically (but not always) silvery in color, and an excellent conductor of electricity and heat.

Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Atomic number The number of protons in an atom. Electron configuration

The atomic number will lead to its electron configuration, and the electron configuration will tell you the element's place in the periodic table. The right end of each row (2nd to 6th rows) has atomic numbers 10, 18, 36, 54, 86. and there are the "noble gases".

The nonmetals lis t which makes up the periodic table includes hydrogen, helium, carbon, sulfur, nitrogen, oxygen, radon, neon, other halogens, and noble gases etc. When we study the elements, it is important to know which elements are metals and which ones are not. If you are trying to learn to distinguish between metals and non-metals, a list ...

The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom. For example, both magnesium and zinc can react with hydrogen ions to displace H 2 from a solution by the reactions: Mg (s) + 2 H + (aq) → H 2 (g) + Mg 2+ (aq) Zn (s) + 2 H + (aq) → H 2 (g ...

Uranium is the 92 nd element on the periodic table. It is located in period 7. It is the fourth element of the actinide series that appears below the main body of the periodic table. Radioactive Elements Every element in the same row or period as uranium is radioactive. What this means is that none of the actinide elements have any stable …
