is yttrium a metal or nonmetal?
312840
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element".

Metals are dense, shiny, good conductors of heat and electricity, and easily lose electrons in chemical reactions. Nonmetals are not dense, dull, do not conduct heat and electricity, and tend to gain electrons. ... They are dull or shiny, and partially conduct heat and electricity.

just by seeing its physical properties. metals are ductile ,malleable, luster,whereas nonmetals are not. ... The main difference between metal and non-metal is that metal give electron to another atom or compound while non metal accept electron from other substances. this is because of their electronic configuration.

The rare earths metals are silver, silvery-white or gray metals which have a high luster, but tarnish readily in air. The rare earth metals have high electrical conductivity.

Metals that have iron in them attract magnets well. Steel is one. Metals like brass, copper, zinc and aluminum are not attracted to magnets. Non-magnetic materials such as wood and glass are not attracted to magnets as they do not have magnetic materials in them.

Yttrium is found in most rare-earth minerals, it is found in some uranium ores, but is never found in the Earth's crust as a free element. About 31 ppm of the Earth's crust is yttrium, making it the 28th most abundant element, 400 times more common than silver.

Stainless steel is a common form of ferrous metal. Non-ferrous metals, on the other hand, do not contain any iron. These metals may be raw metals, purified metals, or alloys. Common non-ferrous metals include aluminum, copper, tin, and precious metals like gold and silver.

The rare earths are silver, silvery-white, or grey metals. The metals have a high luster, but tarnish readily in air. The metals have high electrical conductivity. There are very small differences in solubility and complex formation between the rare earths.

Potassium (group 1) is a metal, and iodine (group 17) is a nonmetal; KI is predicted to be ionic.

A metalloid is an element that possesses properties of both metals and non metals, and which is therefore hard to classify as either a metal or a nonmetal. ... Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids.

They are typically shiny, good conductors of heat and electricity, have a high density, and only melt at high temperatures. ... 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.

A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals tend to have relatively high ionization energy, electron affinity, and electronegativity. They gain or share electrons when they react with other elements and chemical compounds.

Rare earth metals are a group of 17 elements - lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium - that appear in low concentrations in the ground.

Metals tend to be strong and conductive, and have high melting points. However, like nonmetals, their forms occur as a distinct combination of electrons, protons and neutrons. All elements, metal or otherwise, can change state or react.

Chemical Properties of Nonmetals Nonmetals are poor conductors of heat and electricity. ... Unlike metals, nonmetals aren't malleable and ductile. Nonmetals react more with metals than with nonmetals. Usually, nonmetals react with other nonmetals in high temperature.
