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 is the least abundant of the eight rock-forming elements that make up most of the continental crust?
The 3 least abundant elements are Francium (Fr), Astatine (At),and Plutonium (Pu). Francium and Astatine come from the decay of Thorium (Th) and Uranium (U), are much more abundant. At any one time in the entire earth's crust there is only 30 grams of Francium and 25 grams of Astatine. Plutonium is only found in Uranium minerals. The amount of Plutonium is microscopic. Here are the 3 least abundant elements. Lowest 3. 89. Francium 90. Astatine 91. Plutonium
What is the smallest magnitude earthquake that can be felt by humans?

True or false Floods are the least destructive of all geologic hazards to humans and their property?
False
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.
Why is mercury used in barometers instead of water?
Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of mercury, the barometer must be at least 15m high.
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 human beings.
Are all metals safe for humans?
No. Lead, at least, is definitely poisonous.

What are some properties and some of the pros and cons of using plutonium?
only known element to have 5 different solid phases, each with different densities and coefficients of expansion (at least one phase contracts when heated).the metal has a high enough alpha decay rate that it is always hotter than ambient temperature. several people that have held pieces of plutonium say it is like holding a rabbit.being an alpha emitter plutonium dust should never be inhaled or ingested, it will almost certainly cause cancer.it requires far less plutonium than uranium to make a functioning fission bomb.both plutonium and uranium are chemically toxic heavy metals (like lead and mercury) but plutonium is not the most toxic material there is (as many popular authors have written).both plutonium and uranium have multiple chemical oxidation states with a variety of colors.both uranium and plutonium are pyrophoric (i.e. dust can spontaneously ignite in air)etc.
