Promethium is an element with atomic number 61. It has no stable isotopes, the longest lived one has half life 17 years. It can be recovered from spent nuclear fuel in small amounts, but in nature it occurs only in minute amounts associated with uranium, from which it is being formed continually and then decaying, so it never accumulates to any extent. It is one of the lanthanides or 'rare earth' elements, and had never been separated until after nuclear reactors had started to operate, providing a source of it.
What else can I help you with?
Is promethium a solid liquid or gas?
Promithethium is a solid not liquid or gas
What are the states of matter an element can be?
An element can exist in three states of matter: solid, liquid, or gas. The state of a particular element depends on factors like temperature and pressure.
How many phases of element?
Chemical elements may be solid, gas or liquid.
Can an element be a solid liquid or gas?
Yes they always are, unless of course they are a plasma. Only some elements can achieve the plasma state, where it is thousands or millions of degrees and it turns so volatile it is virtually uncontrollable.Some elements in their natural formats:Oxygen - Gas. Turns to liquid in extreme cold.Nitrogen - Gas. Famous for super-cold Liquid Nitrogen.Mercury - Solid. Used in liquid form for thermometers.Hope that helped :)
What is the normal phase for the element?
The normal phase of an element refers to its most stable physical state at room temperature and pressure. It can be solid, liquid, or gas. The normal phase of an element can be determined by observing its melting and boiling points.
Is promethium a solid liquid or gas?
Promithethium is a solid not liquid or gas
What state of matter is promethium at room temperature?
Promethium is a radioactive element with no stable isotopes, so it does not exist in a solid, liquid, or gas state at room temperature. Instead, it exists in a highly unstable and radioactive state, undergoing radioactive decay into other elements. Due to its instability, promethium is typically stored and handled in a controlled environment to prevent contamination and potential health hazards.
What is the physical state of promethium at room temperature?
The radioactive metal, Promethium, is a solid at room temperature and standard pressure. It becomes a liquid at 1040ºC and a gas or vapor at 3000ºC.
What element changes brick?
Solid. Liquid & Gas
Is Li a solid liquid or gas element at room temperature?
gas
What are the states of matter an element can be?
An element can exist in three states of matter: solid, liquid, or gas. The state of a particular element depends on factors like temperature and pressure.
What are the solid element?
The answer is trivial. Some are solid, some liquid and some are gas. The solid ones are those (that at normal conditions) are not liquid (such as mercury) nor a gas (such as oxygen).
What is the difference between a liquid gas solution and a liquid solid solution?
A liquid gas solution is a liquid made up of an element(s) that are normally gas at room temperature. A liquid solid solution is made up of an element(s) that are normally solids at room temperature... Which is around 21 degrees Celsius.
Could you produce liquid cardon dioxide by cooling the gas or by warming the solid?
No because Liquid C02 can only be in solid or gas form not Liquid due to the propeties of the element.
Is wool a solid liquid or a gas?
