Selenium is the only brittle element among the four listed: The others are all metals, with the usual ductility of metals, but selenium is only a metalloid at most.
is magnesium brittle or can it be bent and shaped?
I don't know what is if or if it has one, this site is worthless, get off of it. It won't help you.
Normally magnesium in liquid nitrogen (-196 deg Celsius) turns brittle and can be broken into pieces but when magnesium is fuse lit in liquid nitrogen it forms magnesium nitrate and burns rigorously with bright light. Mg + N2 = MgN2 + heat R . C Salvi rcsalvi@rediffmail.com
WHAT IS RIGID BRITTLE ROCK CALLED? WHAT IS RIGID BRITTLE ROCK CALLED? we have no clue
Elements that are brittle and dull are likely to be nonmetals. Nonmetals tend to have brittle, dull properties compared to metals which are typically malleable and lustrous. Examples of brittle and dull elements include carbon in the form of graphite and sulfur.
yes selenium is brittle, it it is struck it will usually crumble.
Selenium is the most brittle of the elements listed: The others are all full metals, but selenium is only a semi-metal or a metalloid, and ductility, the negative of brittleness, is a property primarily of metals.
Selenium is generally more brittle than sodium. While sodium is a soft, malleable metal that can be easily cut with a knife, selenium, a nonmetal, tends to be more rigid and can break or fracture under stress. The brittleness of selenium makes it more prone to cracking compared to the ductile nature of sodium.
Aluminium would be too brittle, light, and expensive
An aeroplane body is made up of an alloy (meaning: mixture of metals) of aluminium and copper. This is as aluminium is very light and cheap, but it needs copper as aluminium is too brittle. This way the plane have a weight of aluminium but the felexibility of copper!
Selenium is a brittle metalloid, not malleable like metals such as copper or gold. It can easily break, crumble, or be powdered under pressure instead of flattening or bending.
Its ushualy a 50/50 mix of aluminum and magnesium, its quite brittle.
is magnesium brittle or can it be bent and shaped?
Yes Magnesium Can Be Hammered Into Shape !
No, pure magnesium metal is a hard and brittle material that cannot be easily cut with a knife. It is commonly used in alloy form for industrial applications.
acetons
Cast iron, is one example of a non-ductile metal. Unlike ductile metals, copper, steel, aluminium - cast iron is too brittle to be reworked.
