What is metals non metals and metalloids?
Most elements are metals. They are typically shiny, good conductors of heat and electricity, have a high density, and only melt at high temperatures. Metals are ductile and malleable, so their shape can be easily changed into thin wires or sheets. Metals will corrode, gradually wearing away like rusting iron. Nonmetals, are very different from metals. Their surface is dull and they are poor conductor of heat and electricity. As compared to metals, they have low density and will melt at low temperatures. The shape of a nonmetal cannot be changed easily as they tend to be brittle and will break. Metalloids have properties of both metals and non-metals. Some of the metalloids, such as silicon and germanium, are semi-conductors. This means that they can carry an electrical charge under special conditions. This property makes metalloids useful in computers and calculators .
What are diaatomic elements?
Diatomic elements are unique because they are the only seven elements that, when the atoms are under normal conditions in the elemental state, form pairs of atoms. Most elements are organized into crystalline structures, like metals, metalloids and solid nonmetals, or lone gaseous atoms, like the noble gases. Hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine and bromine form H2, N2, O2, F2, Cl2, I2, and Br2, respectively. They are also all of the elements that are non-noble gases at normal pressure and temperature, with the exception of bromine, which is a liquid.
Where do you find the metalloids on the periodic table?
The metalloids are found bordering the stair-step line, except for Aluminium and Astatine. The stair-step line divides the metals and non-metals and is near the right side of the table.
What are the metalloids?
Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal. However, a few elements with intermediate properties are referred to as metalloids. They are sometimes called (and confused with) semiconductors and semimetals. The following elements are generally considered metalloids: * Boron (B) * Silicon (Si) * Germanium (Ge) * Arsenic (As) * Antimony (Sb) * Tellurium (Te) * Polonium (Po) Inclusion of polonium is somewhat academic because all its isotopes are radioactive.
What are unreactive nonmetals that do not react with other elements under normal conditions?
unreactive nonmetals are called noble gases
Why are the staircase elements special?
Because they are metalloids, which have some of the properties of metals and some of the properties of nonmetals, except for aluminum, which is not a metalloid. Because this answer isn't true I tell you why later
What are the four regions of the periodic table?
The regions or sections of the periodic table of elements are, the metals, the transition state elements, the nonmetals, the noble gases, and underneath those regions, the lanthanide series and the actinide series. Hydrogen is sometimes placed above all the other sections, by itself. Technically it is a metal (even though it does not look like one under normal conditions). It has a single valence electron.

What are the major uses of metalloids?
Metalloids are elements that have properties of both metals and nonmetals. They are often used as semiconductors meaning they can be used to conduct electricity under certain conditions. The major uses of metalloids include: Electronics Metalloids are used in transistors and diodes which are essential components of almost all electronic devices. Solar Cells Metalloids such as silicon are used in solar cells to capture and convert solar energy into electricity. Aerospace Metalloids are used in the aerospace industry for various purposes including wiring and fuel systems. Medicine Metalloids can be used to create medical implants and prosthetics as well as drug delivery systems. Industrial Metalloids are used in the production of various industrial products such as steel aluminum and other alloys.Metalloids are also used in the production of optical lenses and as a catalyst in chemical reactions. These elements are essential to many industries and have numerous uses in modern society.

How are medolloids different to medals and non medals?
metalloids are different from metals and non metals as they consist the properties of both metals and non metals. but they cannot put under any of the catergories. just a metalloid

unreactive nonmetals are called noble gases
Which elements are used to make computer chips due to their ability to conduct electricity only under certain conditions?
metalloids
Is the following sentence true or false All elements easily form compounds with other elements?
False. Many elements easily react, such as those in the Alkali Metals and Alkaline Earth Metals, VI, and halogen groups. Other elements react only under the right conditions, such as the transition metals. Some elements, such as the noble gases, do not react or react only under very stringent conditions.
What elements are not malleable and do not conduct electricity?
Insulators. Their valence electrons are tightly bound because the valence shell is close to full or full. Since each shell can only only hold a certain amount of electrons, the number of electrons depends on which shell is the outer or valence shell.
