Why the lithium is the most active alkali metal?
Lithium is NOT the most active alkali metal. Francium is the most active but is available in such trace quantities and radioactive that for practical purposes it is Cesium that is considered most active.
What is the last metal to be discovered?
The last metal to be officially discovered is francium, which was identified in 1939 by Marguerite Perey at the Curie Institute in Paris. Francium is highly radioactive and is extremely rare in nature, making it difficult to study. It is classified as an alkali metal and is produced from the decay of actinium. Due to its instability and short half-life, francium has limited practical applications.
Is americium good conductor of heat?
As it is a metal it would be if you had a large enough quantity to be practical, but because of its radioactivity it is rarely available in amounts larger than a pinhead. So it isn't used for that purpose.
Is roentgenium a metal?
Roentgenium (atomic number 111) - Rg is expected to be a transition metal, although sufficient tests haven't been conducted to prove this. It is at the bottom of the transition metals on the Periodic Table and in the Copper family. The synthetic element next to it (Copernicium) has been confirmed as a transition metal.
Why do some M1 carbines have metal handguards?
Metal slotted handguards were used on the fully automatic M2 for better cooling. Some people now put them on M1 carbines simply because they like the look. They were never used on M1s in the military.
What is a practical application of the process of electroforming?
A metal mold can be made at the cathode of a cell.
What has the author A Delafons written?
A. Delafons has written: '150 practical ideas in metal working production'
What are two practical uses for an acid?
Two practical uses for an acid is for cleaning, like rust off metal and for eating, like when you eat sour foods. Hope it helped! :)
Is rutherfordium a metal or a nonmetal?
Rutherfordium is a synthetic element and is considered a transition metal. It is a highly radioactive element with no practical applications and is not found in nature, being produced through nuclear reactions in laboratories.
How do you get metal?
Metal is actually a chemical element, so there is more than one way to make it, but alloys (two or more elements in a solid solution) are usually needed to make a metal hard enough for practical use.

What is a practical use for the colours of metal salts?
Metal salts, when burned, emit distinct colors due to the presence of metallic ions. This property is utilized in fireworks to produce vibrant and colorful displays. It is also used in flame tests to identify the presence of specific metal ions in compounds.
Cite practical applications of electrolysis?
to separate metal from ore for the purpose of electroplating separation of useful metals using electochemistry
What is aluminimum used for?
Strong and lighweight metal used for contrruction of airplanes.
