that's what I'm trying to figure out too...
No, they are not.
Around 80 percent of the elements on the Periodic Table are metals. Some of the metals are tin, aluminum, francium, lead, and magnesium.
Metals, nonmetals, and metalloids which are elements that have some of the same properties as metals but not all properties to make them a metal
Nearly 100 of the elements are metals.
There several elements tend to be malleable and shiny. Some of them include potassium, sodium, lithium and many more.
For cosmologists, all elements except hydrogen and helium are considered to be "metals".For ordinary purposes, some metallic elements are:lithiumberyliumsodiummagnesiumaluminumpotasiumcalciumscanfdiumtitaniumvanadiumchromiummanganeseironcobaltnickelcopperzincgalliumrubidiumstrontiumyttriumzerconiumniobiummolybdenumtechnetiumrutheniumrhodiumpaladiumsilvercadmiumindiumtincesiumbariumlanthanumceriumpraseodymiumneodyniumpromethiumsamariumeuropiumgadoliniumterbiumdysprosiumholmiumerbiumthuliumytterbiumlutetiumhafniumtantaliumtungstenrheniumosmiumiridiumplatiniumgoldMercurythalliumleadbismuthpoloniumfranciumradiumactiniumthoriumprotactinumuraniumneptuniumplutoniumamericiumcuriumberkeliumcaliforiumeinsteiniumfermiummendeleviumnobeliumetc.
No, not all metals are considered to be elements. Brass for example is a combination of elements but is not an element itself.
Uranium is a member of the actinoids family. These chemical elements are:- they are considered frequently transition metals- they are radioactive elements- some are artificial elements- they have variable valence
The metallic elements in the Periodic Table includes the alkali metals, alkaline earth metals, transition metals, post-transition metals, Lanthanides, actinides, and other elements that are considered metal. You can refer to the metallic elements in Wikipedia for the full details of which elements belong to this classification.
Some elements are metals; others are not. You are familiar with the general physical properties of common metals such as iron, copper, silver and gold. The other metallic elements are those that have similar physical or chemical properties. There are also some other elements that are similar enough, such as antimony, that they considered to be metals by some people. Metals are typically at least somewhat hard, shiny, able to be pressed or hammered into shape without breaking or cracking (unlike glass, for example) and good conductors of electricity and heat.
No, they are not.
Chemical elements, solids, metals
Around 80 percent of the elements on the Periodic Table are metals. Some of the metals are tin, aluminum, francium, lead, and magnesium.
The elements of the d-block are mostly considered to be metals and have a lustrous metallic appearance.
Metals considered minerals are composed of one element. Those elements considered metallic have some shared properties in electrical conductivity and luster.
The Lanthanides consist of the elements in the f-block of period six in the periodic table. While these metals can be considered transition metals, they have properties that set them apart from the rest of the elements.
Metaloids are elements that have characteristics of both metals and non-metals.
