Is polonium a metal non metal or metalloid?
Polonium has a position in the periodic table that could make it a metal, a metalloid or a nonmetal. It is classed as a metal as its electrical conductivity decreases as its temperature rises….

Is polonium a post transition metal or metalloid?
Typically the elements of the post-transition metals include any metal in groups 13, 14, and 15 which are aluminum, gallium, indium, tin, thallium, lead, and bismuth. Polonium is often classified as a post-transition metal as well.
Is polonium a metal on the periodic table?
polonium (Po), a radioactive, silvery-gray or black metallic element of the oxygen group (Group 16 [VIa] in the periodic table). The half-lives of its isotopes range from a fraction of a second up to 103 years; the most common natural isotope of polonium, polonium-210, has a half-life of 138.4 days.
Which element is a metalloid polonium?
The percentage appearance frequencies of the elements most frequently identified as metalloids are boron (86), silicon (95), germanium (96), arsenic (100), selenium (23), antimony (88), tellurium (98), polonium (49), and astatine (40).
Why is polonium not considered a metalloid?
All three are likely to be post-transition metals, rather than metalloids. Polonium has a silvery, metallic appearance; conducts electricity like a metal; and has the electronic band structure of a true metal (rather than a semimetal like antimony).
What type of element is polonium?
metal
Polonium is located in Group 16 and period 6 in the periodic table of elements. It’s classified as a metal because polonium’s electrical conductivity decreases as its temperature rises, according to the Royal Society of Chemistry.
Is polonium paramagnetic or diamagnetic?
Magnetic Type of the elements
| Hydrogen | Diamagnetic | Thallium |
|---|---|---|
| Helium | Diamagnetic | Lead |
| Lithium | Paramagnetic | Bismuth |
| Beryllium | Diamagnetic | Polonium |
| Boron | Diamagnetic | Astatine |
Why is polonium considered a metalloid?
The elements boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are considered metalloids. Metalloids conduct heat and electricity intermediate between nonmetals and metals and they generally form oxides.
Is antimony a metal?
Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. A lead-antimony alloy is used in batteries.
What are facts about polonium?
Polonium (Po) has an atomic number of eighty-four, and the same number of protons in the nucleus of one atom . It is the element with more isotopes than any other, and all of them are radioactive. Interesting Polonium Facts:
What are the common uses of polonium?
Polonium is an alpha-emitter,hence it is used in antistatic devices and for research purposes.
What family does polonium belong to?
Polonium is a very rare radioactive element. Chemically, it is represented with the symbol Po. In the periodic table, it is placed in group 16 which is also known as chalcogen family. Other members of this family include Oxygen, Sulfur, Selenium, and Tellurium. It is the heaviest chemical element of this group.
What are the characteristics of polonium?
Polonium is a rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth.
