What else can I help you with?
Can an element be both metal and non-metal?
no, but there are metalloids, which have properties of both metals and non metals
Why is boron a semi-metal?
Boron is considered a semi-metal because it exhibits properties of both metals and non-metals. It has some metallic characteristics, such as electrical conductivity, but also shows non-metallic properties like brittleness. This dual behavior places boron in the category of semi-metal.
Is silicon a metal nonmetal or a metalloid?
Silicon is a metalloid, which means it has properties of both metals and nonmetals. It has some characteristics of metals, such as conductivity, but also some nonmetallic properties, like brittleness.
Are boron and silicon metals?
They are both considered to be Metalloids meaning they have some metal characteristics and some non-metal characteristics.
Are there any metals that have different properties than other metals?
Each metal has its own specific set of properties. Some metals are better conductors than others. Some metals have higher melting temperatures than others, there is even a metal that is in a liquid state at room temperature, that metal is called Mercury. Same metals are more malleable than others. They also differ in weights, in density.
Is germanuim a metal metalloid or a nonmetal?
Germanium is a metalloid. It has some properties of both metals and non metals. It belongs to group 14.
Is arsenic a metal nonmetal or metalloid?
Arsenic is a metalloid, which means it has properties of both metals and nonmetals. It has some characteristics of metals, like being shiny and brittle, but also has nonmetal properties, like being a poor conductor of electricity.
What are chemical properties of metal?
Some chemical properties of metals are that they have good electrical and thermal conductivity. Metal also form positive ions or cations and ionic bonds. When exposed to air and moisture, many metals tend to corrode.
Why hydrogen placed in activity chart of metals when it is not a metal?
Hydrogen may not be a metal, but it does share some properties with metals. It forms a positive cation, H+, and can displace some metals in displacement reactions. Basically, it is included in the reactivity series because it is able to displace some metals but not others.
What are mettaloids?
Metalloids are the border lines between the metals and the nonmetals in the Periodic Table.
Do elements that have some properties of metals and some properties of non metals are called halogens?
Halogens refer specifically to a group of elements in the periodic table (Fluorine, Chlorine, Bromine, Iodine, Astatine) with distinct properties, rather than elements with mixed metal/non-metal properties. Elements with mixed properties are often referred to as metalloids or semimetals, such as Boron, Silicon, Arsenic, and Antimony.
Why is boron a metal?
Boron is not a metal; it is classified as a metalloid. It possesses some properties of metals like electrical conductivity but also displays non-metallic characteristics like being brittle. Boron's classification as a metalloid is due to its intermediate properties between metals and non-metals.
