What element is common among all of the biomoleules and essential for life on earth?
All the bio molecules are organic compounds. Carbon is the element common among all these compounds. Carbon is a tetravalent element.
Is polonium most radioactive element?
no it is not i believe it is uranium uranium is only a mild alpha emitter, radium is most radioactive natural element, then polonium. The best candidate among the first 92 elements is probably astatine. All three of its naturally occurring isotopes have half-lives of less than a minute.
Which element will sink in both water and mercury?
Any element denser than 1bout 13.5 g/cm^3 will sink in both water and mercury. Such elements include gold, platinum, tungsten, osmium, and uranium among others.
What south American country that lists uranium among its mineral resources?
Argentina and Brasil have uranium mines.
Which country in in South American country lists uranium among its mineral resources?
Brazil is the South American country that lists uranium among its mineral resources. It has significant reserves and is one of the world's top uranium producers.
Would there be a gravitational force acting among the particles of a helium nucleus or the particles of a uranium nucleus?
There is a stronger gravitational force acting among the particles of a uranium nucleus compared to the nucleus of helium. This is because uranium has more mass than helium.
What elements is most electonegative phosphorus carbon chlorine boron iodine?
Chlorine is a group 17 element and has the highest electronegativity among the elements given.
Would there be a stronger gravitational force acting among the particles of a helium nucleus or the particles of a uranium nucleus?
There is a stronger gravitational force acting among the particles of a uranium nucleus compared to the nucleus of helium. This is because uranium has more mass than helium.
Why is diamond a mineral if it is composed of carbon and we define mineral as inorganic?
Some minerals are called elemental minerals. Among those are gold, silver, copper, and others. Carbon exists in a variety of allotropes, which are different forms of the same element. Diamond and graphite are both allotropes and minerals consisting entirely of the element carbon. To be a mineral, a substance needs to be inorganic, and carbon is a naturally occurring inorganic element, found on Earth long before life evolved.
Which country in South America has uranium among it mineral sources?
Argentina and Brasil
Which lanthanide element and which transition element have only radioactive isotopes?
All or almost all elements have radioactive isotopes if artificial isotopes are included. Among the naturally occurring elements, uranium, polonium, radium, and thorium have naturally occurring radioactive isotopes on earth.
What south American country lists uranium among its mineral resources?
Argentina and Brazil
