What does curium look like?
Curium is a silvery-white, radioactive metal that tarnishes in air. It is not found in the natural environment and is typically produced in laboratories through nuclear reactions. Its most stable form is curium-247.
What is an element on the periodic table named after a scientist?
Curium: (Symbol Cm, At No 96, At Wt 247, Melt Pt 1337ºC, Boil Pt 3110ºC) is named after Pierre and Marie Curie.
What is the longest lasting synthetic periodic element?
A good candidate would be curium 247 (247Cm), which has a half-life of 1.56 × 107 years. That's 15,600,000 years (15.6 million years).
What page is the word rue on in the bronze bow?
the bottom of page 247 "He left a concoction of Rue and departed, with a resigned shrug of his shoulders and a gentle pity in the wise eyes behind their wrinkled lids" Hope this helps :)
What pressure exists in a 200-L tank containing 5.0 kg of neon gas at 300 K?
I believe you would have to use the formular PV=nRT for this problem. First convert n from kg to moles, knowing that Neon is 20.1797 g/mol: (5 kg x 1 mol) / .0201797 kg = 247 mols Next, identify all the variables: P = ? V = 200-L T = 300 K n = 247 mols R = 0.08206 (L*atm)/(K*mol) Now plug the values into the formula: PV = nRT therefore P = nRT /V P = (247 mols)(0.08206 (L*atm)/(K*mol))(300 K) / 200-L = 30.4 atm
What is the atomic mass of curium?
IUPAC consider the atomic weight of curium 247; this is the mass of the isotope 247Cm, the curium isotope with the longest half life.
What is the equation for decay of californium 251?
251Cf --> 247Cm + 4He 247Cm --> 243Pu + 4He 243Pu --> 243Am + e- 243Am --> 239Np + 4He 239Np --> 239Pu + e- 239Pu --> 235U + 4He 235U --> 231Th + 4He 231Th --> 231Pa + e- 231Pa --> 227Ac + 4He 227Ac --> 223Fr + 4He, 227Th + e- 223Fr --> 219At + 4He, 223Ra + e- 227Th --> 223Ra + 4He 219At --> 215Bi + 4He, 219Rn + e- 223Ra --> 219Rn + 4He 215Bi --> 215Po + e- 219Rn --> 215Po + 4He 215Po --> 211Pb + 4He 211Pb --> 211Bi + e- 211Bi --> 207Tl + 4He, 211Po + e- 207Tl --> 207Pb + e- 211Po --> 207Pb + 4He 207Pb: stable
What is the atomic mass number of the curium?
The atomic number if curium (Cm) is 96 and its approximate atomic mass is (247). The () denotes that the exact mass is not confirmed, as curium is radioactive and unstable. So it is not easy to calculate the exact mass of all its isotopes.
What is the balance nuclear equation for alpha decay of 251 N0?
The balance nuclear equation for the alpha decay of ^251No (Nobelium-251) is: [ ^{251}{102}No \rightarrow ^{247}{100}Fm + ^{4}_{2}\alpha ] In this equation, Nobelium-251 decays into Californium-247 while emitting an alpha particle ((^4_2\alpha)). The mass and atomic numbers are conserved in the reaction.

What does curium look like?
Curium is a silvery-white, radioactive metal that tarnishes in air. It is not found in the natural environment and is typically produced in laboratories through nuclear reactions. Its most stable form is curium-247.
How many neutrons does the most naturally occurring isotope of curium have in its nucleus?
Curium is an artificial chemical element. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; and atomic mass is 247 so no of neutrons is 151.
How many naturally occurring isotopes are in curium?
Practically none, though it seems plausible that trace amounts of Cm-247 exist in uranium ore.
What is an element on the periodic table named after a scientist?
