What else can I help you with?
Is lithium manmade?
No. Lithium is a naturally occurring element.
What is the origin of francium?
Francium is a naturally occurring radioactive element that is produced as a decay product of uranium and thorium. It is found in tiny amounts in uranium and thorium ores. Francium was first discovered in 1939 by Marguerite Perey in France.
What are the 4 naturally liquid elements?
The four elements that are naturally liquid at room temperature are: mercury, bromine, francium, and cesium. Mercury and bromine are the most common naturally occurring liquid elements.
Is francium strong?
Francium is a soft, highly reactive metal. It is the most unstable of all the naturally occurring elements due to its large atomic size and low electronegativity. It readily reacts with other elements, so it is typically stored in inert gas to prevent this.
Does francium have a high or low boiling point?
Francium has a very low boiling point of approximately 677°C (1251°F). It is the second rarest naturally occurring element, and its melting and boiling points are among the lowest of all the elements.
Are minerals manmade?
No. By definition a mineral is naturally occurring.
Is tar manmade?
No, it is a naturally occurring petrochemical.
Is lithium manmade?
No. Lithium is a naturally occurring element.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
Is zinc manmade or naturally occurring?
Both. Zinc can be found in nature and also can be manmade.
Is a dress manmade or is it from nature?
A dress is manmade. It is created by humans using a variety of materials such as fabric, thread, and embellishments. It is not naturally occurring in nature.
Is pumice natural or manmade?
Pumice is a naturally occurring volcanic rock.
Is zircon manmade?
Zircon itself is a naturally occurring mineral, so it is not manmade. However, some zircon gemstones undergo treatments, such as heat treatment, to enhance their color or clarity, but the base mineral itself is natural.

Give the names of naturally occurring elements?
In the attached list manmade elements are: technetium, promethium and the elements with atomic number between 94 and 118.
Is hydrogen manmade?
Hydrogen is the most abundant element in the universe and is naturally occurring. However, most of the hydrogen used by humans is produced through industrial processes such as steam methane reforming or electrolysis of water.
