Plutonium has six allotropes.
For the properties see the link below.

Yes, many reactors use uranium as their nuclear fuel, but some use plutonium or a uranium-plutonium mix.
Matter is anything that has mass and occupies a space. Matter has 2 properties physical properties and chemical properties. And 2 physical properties include mass and shape (solid, liquid and gas).Other physical properties of molecular matter include:VolumeColorOdorLusterHardnessMelting PointFreezing PointBoiling PointDensityMalleabilityDuctilityConductivity
three
It is not entirely correct to talk about "the" three phases. There are actually more than three phases of matter. In the case of water, the three "main" phases are called: "ice" (for solid water), "liquid water" or just "water" for the liquid phase, and "water vapor" for the gaseous phase. In the case of water, and many other substances, there is also a "supercritical" phase (among others). I don't think this one has a special name, in the case of water. The supercritical phase is used for dry cleaning; although it is more common to use carbon dioxide for this purpose, since it requires less temperature and pressure.
Wax, like all matter, comes in many phases. What are the three possible phases? gas. liquid, and solid
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.

There are actually quite a few more phases of matter, but the commonest three known are solid, liquid, and gas. Some texts cite as many as fifteen. At super-cold temperatures a phase with unusual properties, known as BEC can be manifest (Bose-Einstein Condensate); at very high temperatures, electrons can dissociate from their atoms in the Plasma phase. Between and within phases are sub-phases, sone of which describe matter during changes in phase (phase transition) and some of which are stable.
Chemical elements may be solid, gas or liquid.
Two phases: a solid one = the paper, and a mobile one = the liquid you put on the paper.
cornstarch has many properties. when hit hard, it is a solid. when touched lightly it is liquid.
Uranium is a natural chemical element, plutonium is an artificial element (but note that plutonium exist also naturally in the earth crust in extremely low concentrations). Uranium has the atomic number 92 and plutonium 94. The critical mass of uranium is greater than the critical mass of plutonium. The melting and boiling points of U and Pu are different. Uranium has an orthorombic crystalline structure; the structure of plutonium is monoclinic. And many other physical and chemical properties are different.
Plutonium has 94 electrons.
