Where are less reactive metals nonmetals and metalloids on the periodic table?
Less reactive metals are typically located towards the bottom left of the periodic table, such as in Group 1 and Group 2. Nonmetals are often found towards the upper right of the periodic table, including the elements in Group 17 (halogens) and Group 18 (noble gases). Metalloids are located along the staircase line between the metals and nonmetals on the periodic table, such as elements like boron, silicon, and germanium.
Which elements in the periodic table are nonmetals and which are metalloids?
Nonmetals on the periodic table include elements such as hydrogen, helium, carbon, oxygen, and nitrogen. Metalloids are found along the staircase on the periodic table and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium.
How would you describe the ability of most metalloids to conduct heat and electricity?
Most metalloids have intermediate conductivity properties, meaning they are not as good conductors of heat and electricity as metals, but better than nonmetals. This is due to their partial metal and nonmetal characteristics, which allow for some electron mobility within their structure.
Which contains the most elements metals transition metals or metalloids?
Im pretty sure that there are more transition metals than metals or metalloids
Logically, though, it is impossible for there to be more transition metals than metals!
The latest IUPAC periodic table recognises 114 elements. Borders are a little blurred but there are about 18 non-metals, about 6 metalloids, and about 90 metals.
Of the ~90 metals, 38 are transition metals, 30 are lanthanoids and actinoids, and the remaining ~22 are "main group" metals.
On this basis of classification, transition metals are the largest single group
What are the two metalloids in the nitrogen family?
The two metalloids in the nitrogen family are arsenic and antimony.
Metalloids generally do not form cations as readily as metals do due to their intermediate properties between metals and nonmetals. However, under certain conditions, metalloids like boron and silicon can form cations by losing electrons to achieve a stable electron configuration.
Do all metals and metalloids have luster?
No, not all metals and metalloids have luster. Luster is a property of metals that allows them to reflect light, giving them a shiny appearance. Some metals and metalloids may lack luster due to factors such as surface oxidation or impurities.
Under what conditions will metalloids conduct heat and electricity?
Metalloids can conduct heat and electricity under conditions where they have partially filled valence electrons. This allows them to exhibit some metallic properties. However, metalloids are not as efficient conductors as metals nor as insulators as nonmetals.
What property makes certain metalloids useful as switches to turn small electric current on and off?
Metalloids like silicon and germanium have semiconducting properties, which allow them to change their conductivity with small variations in temperature or applied voltage. This property makes them useful as switches in electronic devices to control the flow of small electric currents by turning them on and off.
Is mercury a metal or metalloid?
Symbol: Hg
Atomic Weight: 200.59
Discovery: Known to the ancient Hindus and Chinese. Mercury has been found in Egyptian tombs dating to 1500 B.C.
Electron Configuration: [Xe] 4f14 5d10 6s2
Word Origin: from the Planet Mercury; Hg is the symbol for Hydrargyrum, which means liquid silver
Properties: Mercury has a melting point of -38.842°C, boiling point of 356.58°C, specific gravity of 13.546 (20°C), and a valence of 1 or 2. Mercury is one of the few elements that is liquid at ordinary room temperatures. Mercury is a heavy, silvery-white metal. It is a relatively poor conductor of heat, but a fair conductor of electricity. Mercury readily forms alloys with other metals, called amalgams. An electrical discharge will cause mercury to combine with the noble gases argon, krypton, neon, and xenon. Mercury and its compounds are highly poisonous. Mercury is readily absorbed across unbroken skin or though the respiratory or gatroinstentinal tract. It acts as a cumulative poison. Mercury is very volatile in air. When room temperature air (20°C) is saturated with mercury vapor, the concentration greatly exceeds the toxic limit. The concentration, and thus the danger, increases at higher temperatures.
Uses: Mercury is amalgamated with gold to facilitate the recovery of gold from its ores. Mercury is used to make thermometers, diffusion pumps, barometers, mercury vapor lamps, mercury switches, pesticides, batteries, dental preparations, antifouling paints, pigments, and catalysts. Many of the salts and organic mercury compounds are important.
Sources: Mercury rarely occurs free in nature. It's chief ore is cinnabar, HgS. Mercury is obtained from cinnabar by heating the cinnabar in air and condensing the vapor.

Does metalloids have properties of both metals and inner transition metals?
Metalloids are unlike the inner transtion metals and all other metals. They are giant molecules whose bonding could be described as covalent. However consider silicon - perhaps the most widey used metalloid- it has a structure like diamond with tetrahedral bonds- but it is a semiconductor- this is because in molecular orbital terms the antibonding orbitals are sufficiently close to the energy of the bonding orbitals (band gap -using the nomenclature of band theory) for thermal excitation into the antibonding orbitals to take place.This is an oversimplification.
No, metalloids are not all man-made. Metalloids are a group of elements on the periodic table that have properties of both metals and nonmetals. Some metalloids, like boron and silicon, are naturally occurring elements.
Are metalloids the best conductors of heat and electricity?
No, metalloids are not the best conductors of heat and electricity. Metals are generally better conductors of heat and electricity compared to metalloids. Metalloids have properties that are intermediate between metals and nonmetals.
What are the general and characteristics of metals and non metals and metalloids?
Metals:
Shiny 'metallic' appearance
Solids at room temperature (except mercury)
High melting points
High densities
Large atomic radii
Non Metals:
High ionization energies
High electronegativities
Poor thermal conductors
Poor electrical conductors
Brittle solids
Little or no metallic luster
Gain electrons easily
Metalloids:
Electronegativities between those of metals and nonmetals
Ionization energies between those of metals and nonmetals
Possess some characteristics of metals/some of nonmetals
Reactivity depends on properties of other elements in reaction
Often make good semiconductors
What are metalloids on the periodic table?
Metalloids are elements found along the staircase on the periodic table between metals and nonmetals. They exhibit properties of both metals and nonmetals, such as conducting electricity but not as well as metals. Some common metalloids include boron, silicon, germanium, arsenic, antimony, and tellurium.
Is metalloids solid at room temperature?
Yes, most metalloids are solid at room temperature. Examples include silicon, germanium, arsenic, antimony, and tellurium. These elements exhibit properties that are intermediate between metals and nonmetals.
Which is a metalloid Si Na or Cl?
Silicon (Si) is a metalloid. Sodium (Na) and chlorine (Cl) are not metalloids.
Do metalloids react with acid?
Metalloids as a group have varying reactions with acids depending on the specific metalloid and acid involved. For example, silicon does not react with dilute acids, while boron can react with strong acids to form different compounds. Overall, metalloids can show acidic or amphoteric behavior, meaning they may react differently depending on the specific conditions.
What are similarities of metals metalloids and nonmetals?
Metals, metalloids, and nonmetals are all types of elements found on the periodic table. They each have unique physical and chemical properties that distinguish them from one another. All three types play important roles in the structure and behavior of matter.
Tellurium is a metalloid, or a semi metal. This can be considered a metal or a non-metal as its properties put it in the metalloid category of the Periodic Table.
Is gatorade a metal nonmetal or a metalloid?
As a physical mixture Gatorade would not be up for consideration to classify as any of these. We normally only classify ELEMENTS as metals, metalloids, and non-metals. It is mostly composed of water - which is composed of the non-metals hydrogen and oxygen, sugars - the molecules of which are made up of the non-metals hydrogen, oxygen and carbon (although carbon is occasionally classified as metalloid), and some salts of sodium and potassium - both metals, but bonded with chlorine, a non-metal, in the salts.
