What is the atomic mass of polonium?
The standard atomic weight of polonium is [210], after IUPAC rules.
What is the atomic mass of polonuim?
Polonium is a metal element. Atomic mass of it is 209.
What is the charge of polonium 210 nucleus?
The atomic no for Polonium is 84 so its nuclear charge is + 84.
What is the atomic structure of polonium 210?
I am pretty sure it Alpha radiation because you cannot be effected by it if it is outside the body, all other types of radiation can penetrate the skin
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
How many neutrons are in Pb-210?
The "210" is the mass number. The mass number is the sum of the number of neutrons and the number of protons. So if you can locate a Periodic Table, you can see that lead's atomic number of 82, which means it has 82 protons. If you do a little subtraction (210-82), you can find the number of neutrons in this particular isotope, which is 128.
How many neutrons are in lead with a mass number of 210?
Number of neutrons = Mass number - atomic number = 210 - 82 = 128
What is the Atomic mass of astatine?
The atomic mass of astatine is 209.9871 atomic mass units (amu). The atomic mass is given for the longest lived isotope of astatine, which is astatine-210, with a half life of 8.3 hours.
What is the atomic number of astatine?
The atomic number of astatine (At) is 85.The atomic weight of At is 210 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
What is the mass number of polonium?
Polonium is a metal element. Atomic mass of it is 209.
What type of radioactive decay occurres when lead-210 becomes bismuth-210?
When lead-210 undergoes radioactive decay to become bismuth-210, it undergoes beta decay. In this process, a neutron in the lead-210 nucleus is converted into a proton, emitting a beta particle (an electron) and an antineutrino. This transformation increases the atomic number by one, resulting in the formation of bismuth-210 while the mass number remains the same.
The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Given the molecular formula mass of 210 amu, the subscripts for C, H, and O in the actual molecular formula can be determined as follows: the atomic mass of carbon (C) is 12 amu the atomic mass of hydrogen (H) is 1 amu the atomic mass of oxygen (O) is 16 amu Thus, the subscripts for C, H, and O are calculated as follows: Subscript for C: 210 amu / 12 amu = 17.5 (approx. 18) Subscript for H: 210 amu / 1 amu = 210 Subscript for O: The compound doesn't contain oxygen since the sum of 18 (C) and 210 (H) exceeds 210, which is the given molecular formula mass.
