Which elements in the periodic table are metalloids or have semimetallic properties?
The elements that are commonly recognized as metalloids or semimetals are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). These elements exhibit properties of both metals and nonmetals, such as being good conductors of electricity but also brittle and less malleable.
What are semi-conductive metalloids?
Metalloids are known as semi-conductors meaning they can conduct electricity, but they are not good conductors. Metals are good conductors. Non-metals are bad conductors.
Does 15 a group elements form ionic bonds?
Group 15 elemnts, N, P, do form ionic compounds, nitrides and phosphides, N3- and P3- ions the heavier elements arsenic antimony and bismuth also form -ide compounds some arsenides are mainly ionic but the antimonides and bismuthides are less so. Wikipedia entries on the arsenides, antimonides and bismuthides are not very good so use a text book!
What is the octet rulewhich element is the exception?
Some elements that are known to violate the octet rule are: Hydrogen, Helium and Lithium (two electrons) Aluminum and Boron (less than octet but will form an octet if possible), Period 3 elements with p orbitals (more than an octet using empty d orbitals), noble gas compounds (more than an octet), and elements like nitrogen with an odd number of electrons (form free radicals when octets are not possible).
What can be used to absorb neutrons to control the chain reaction during nuclear fission?
Boron is most commonly used, mixed to make an alloy with steel which is used for the control rods. Soluble boron can also be used mixed with the reactor primary water, but this is for more long term reactivity adjustment. Other good neutron absorbers are cadmium and hafnium.
What element has both metallic and nonmetallic properties?
We generally refer to these elements as semiconductors. There is something akin to a "diagonal line of elements" in the periodic table that separates the metals from the nonmetals. Elements on the left of this diagonal are metals, and elements on the right are nonmetals. The elements that make up this diagonal are boron, silicon, germanium, arsenic, antimony, tellurium, polonium, and astatine, and they have both metallic and nonmetallic properties. awesome mean something good.
Good sciens words that start with A?
Actinium, Aluminum, Americium, Antimony, Argon, Arsenic and Astatine are chemical elements. They begin with the letter A.
Is antimony a good conductor of heat and electricity?
Yes, antimony is a good conductor of both heat and electricity.
Are metalloids Conductor of heat or electricity?
They are only fair to high (intermediate) conductors of electricity and heat, except that silicon is a good heat conductor. Metalloids include boron, silicon, germanium, arsenic, antimony, and tellurium.

Is boron a good conductor of electricity?
Boron is not a good conductor of electricity at room temperature, but is a good conductor at a high temperature.
In group 3A of periodic table all elements are metals while Boron is metalloid why is it placed in this group?
Although boron is a metalloid and the other elements in group 3A of the Periodic Table are metals, it is placed with group 3A because it has three valence electrons at its highest-energy orbitals. It is also a good conductor of electricity.
What element has a name that means not good for monks?
Antimony/antimonium
Is boron a good insulator?
Yes
Is boron a good conductor of heat?
Yes it is but it is not good for electricity!!
Is boron a good heat conductor?
Yes it is but it is not good for electricity!!
Metal used in control rods of nuclear reactor?
Usually boron is alloyed with steel, boron is a very good neutron absorber.
