Is polonium a metal or 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.
How do you know if an element is a metal nonmetal or metalloid?
Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table.
How do you tell if something is a metal or metalloid?
The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids. When elements combine to form compounds, there are two major types of bonding that can result.
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.
Why is polonium not a 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 fluorine a metal nonmetal or metalloid?
Its atomic number is 9 and its atomic weight is 19, and it’s a gas at room temperature. It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive. It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2).
Is fluorine a metal or nonmetal?
It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2). It has 5 valence electrons in the 2p level….Quick Reference Table.

What is chlorine a metal nonmetal or metalloid?
Chlorine is a non-metal. Metals are good conductors of heat and electricity, and are malleable.
Is Fluorine a metalloid?
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals….Metalloid.

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.
