it's called a non metal
Because it doesn't have the properties of a metal.
When a compound lacks water, it is called anhydrous.
Talc is not magnetic because it is a non-metallic mineral composed mostly of hydrated magnesium silicate. It does not exhibit magnetic properties as it lacks the necessary elements to interact with magnetic fields.
A non-metal is an element on the periodic table that does not have the properties of a metallic element, such as malleability. Nonmetals are usually found in nature as gases or weak, brittle solids. All group 17 and 18 elements are nonmetals, as well as hydrogen, carbon, nitrogen, oxygen, phosphorous, sulfur, and selenium.
Newlands' Law of Octaves, proposed in 1865, has several limitations. It only applies to the first 16 elements of the periodic table, as it was based on the observation of similar properties in every eighth element, which does not hold for heavier elements. Additionally, it does not account for the existence of noble gases and the transition metals, and it fails to explain the periodicity observed in elements beyond the initial grouping. Consequently, it lacks the predictive power and comprehensive framework that later periodic laws, such as Mendeleev's periodic table, provided.
That would be the noble gases
It nonmetal ! I know this one! I had it on a worksheet!
Silicon is a metalloid, which means it has properties of both metals and non-metals. It is often considered a semiconductor due to its electrical conductivity, but it lacks typical metallic properties like luster and ductility.
Chlorine is considered a nonmetal because it lacks metallic properties such as malleability, ductility, and conductivity. It tends to gain electrons in chemical reactions, forming anions, rather than lose electrons like metals do.
Iron is a metal because it has metallic properties such as being malleable, ductile, and having luster. Sulfur is a non-metal because it tends to gain electrons in chemical reactions, forming negatively charged ions, and it lacks the luster and malleability of metals.
A mineral that lacks silicon or oxygen is called native elements. These minerals consist of a single element or a combination of elements without silicon or oxygen in their chemical composition. Examples include gold, silver, copper, and sulfur.
Silicon is classified as a metalloid because it has properties of both metals and nonmetals. It does not conduct electricity as well as metals but can conduct under certain conditions. Additionally, silicon has a crystalline structure like metals but lacks the luster and malleability typically associated with them.
NONMETAL
Because it doesn't have the properties of a metal.
nonmetals
When a compound lacks water, it is called anhydrous.
Sulphur is not magnetic because its atoms do not have unpaired electrons to create a magnetic field. Magnetic properties are typically associated with elements that have unpaired electrons, which sulphur lacks.
