Plutonium, lead, and Mercury are all heavy metals. If you knew nothing but that, you should be able to guess that the correct answer is iron.
(It might also help to try the various elements in the phrase "Fortified with ____!", and see which of them sounds most familiar from the labels on vitamins or cereals.)
What else can I help you with?
Which was least likely to have been a component of earth?
Plutonium is least likely to have been a component of Earth as it is a man-made element that is not naturally occurring in significant quantities.
What is the least abundant of the eight rock-forming elements that make up most of the continental crust?
The least abundant of the eight rock-forming elements in the continental crust is potassium, with an average abundance of around 2.6%. The other rock-forming elements are oxygen, silicon, aluminum, iron, calcium, sodium, and magnesium.
What is the air pollutant least successfully removed from the air by technologies in developed nations?
Mercury is one of the air pollutants that is least successfully removed from the air by technologies in developed nations due to its volatility and tendency to persist in the atmosphere. Advanced emissions control technologies are required to effectively capture and remove mercury emissions from industrial processes.
What is the smallest magnitude earthquake that can be felt by humans?
The smallest magnitude that could be felt by humans is at least a 5.5
What minerals are in mercurys rock?
In the planet Mercury, closest to the Sun? Difficult to know for sure, because we've never landed a probe there. But Mercury is the second-densest planet, after Earth. So we expect that Mercury has a fairly large iron core, with a crust at least vaguely similar to Earth's, made up of silicate rock.
Is plutonium least poisonous to humans?
Plutonium is a very toxic element; also is a radioactive element.
Which is least poisonous to human plutonium lead or iron?
Iron is the least poisonous to humans among plutonium, lead, and iron. Iron is an essential nutrient for the body and is required for making red blood cells, while lead can cause various health issues even in small amounts, and plutonium is a radioactive element that can be extremely harmful if ingested or inhaled.
Is plutonium-238 a liquid?
no. it is a solid isotope and is the least harmful of the plutonium isotopes.
Are all metals safe for humans?
No, not all metals are safe for humans. Some metals can be toxic when ingested or inhaled in high amounts, such as lead, mercury, and arsenic. It is important to be aware of the potential risks of exposure to certain metals and follow safety guidelines to minimize any negative health effects.
Can you get power from the radioactive element plutonium?
Yes, at least theoretically
What is the date when mercury was descoverd?
