Ia astatine a metal metalloid or a nonmetal?
Astatine is a nonmetal and halogen.
Which 2 elements along the stair step line are not metalloids?
Polonium and astatine may or may not be included as metalloids (depends on your periodic table). Overall, polonium is closer to being metal than a metalloid; astatine closer to being non-metal than metalloid
Barium metal or metalloid?
According to Lange, Semi-metals are: boron, silicon, germanium, arsenic, antimony, tellurium, polonium and astatine. Although, polonium and astatine, according to some authors, are not semi-metals. Gallium is a metal (4. period, 13th (IIIa) group).
When was astatine found?
In 1940, astatine was produced in a lab at the University of California by the three scientists named Carson, Mackenzie, and Segre. This element is classified as a semi-metal and has the atomic number of 85.
Is NaCl a metal or non-metal?
Sodium chloride is a compound, not a chemical element.
Is astatine a good conductor of electricity?
Astatine is not a good conductor of electricity. This is because it is a non-metal. All non-metals do not conduct electricity, and all metals do. The two exceptions are carbon and silicon, which are non-metals, but conduct electricity well.
Is it true that astatine is a non-metal?
Yes. A solid nonmetal of the halogen family.
Ia astatine a metal metalloid or a nonmetal?
Astatine is a nonmetal and halogen.
What element is a metal and a non metal?
These types of elements are called metalloids. There are a few: Boron, Silicon, Arsenic, Germanium, Antimony, Tellurium, and Astatine. Hope that's what you were looking for!
What is the radioactive metal used in medicine?
Astatine (At)
Is boron a non-metal?
No, Boron (B) is classified as a metalloid, which is an element with propertyies intermediate between metals and nonmetals. Other metalloids are: Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium and Astatine.
Is astatine a metal nonmetal or metalloid?
No, the guy before me was wrong, Astatine is a Metalloid and it is used in the Radiotherapy of cancer.
Is astatine similar to strontium in chemical properties?
Astatine is a heavy halogen; no similarities with strontium (alkaline earth metal).
Is astatine an alkaline metal?
No. Astatine is a halogen. The alkaline earth metals are in the column second from the left of the periodic table.
What is the color of sodium astatine?
Sodium astatine does not exist, as astatine is a halogen element while sodium is an alkali metal. Sodium is typically silver-white in color, while astatine is expected to have a dark, metallic appearance.
What is the most reactive non-metal?
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
Is astatine a conductor of heat or electricity?
Astatine is not a good conductor of heat or electricity. It is a semiconductor, meaning it has properties between those of a metal and an insulator.
