Atomic Mass

The element with an atomic mass of 222 amu is radon (Rn).

Neon's atomic mass is approximately 20.1797 atomic mass units.

The total mass of protons and neutrons in the nucleus was traditionally called the 'Atomic weight', but in more recent times the term 'Relative Atomic Mass' has been used instead. This is really a better term as the mass is relative, and not an actual weight in terms of a weight unit like grams.

One has to distinguish between the mass of the element as it exists in most common form, which may be a mixture of isotopes, and the mass of one particular isotope where all atoms are identical. thus Uranium as found in nature is neither 235 or 238, but a weighted figure depending on proportions of the isotopes.

the atomic mass of seaborgium is 263.o amu. ------------------------- Seaborgium has 16 isotopes and 1 isomer; each isotope has a different atomic mass. See for details at: http://en.wikipedia.org/wiki/Isotopes_of_seaborgium.

There are various isotopes of tin with different atomic mass. The average atomic mass of tin is 118.71 amu. The symbol commonly used for tin is Sn.

The atomic mass of an element is located below the element's symbol in the periodic table. It is typically shown as a decimal number. The atomic mass represents the average mass of an atom of that element, taking into account the different isotopes and their relative abundance.

The atomic mass of indium is approximately 114.82 atomic mass units.

The atomic mass of osmium (Os) is 190.23 grams per mole.

To find the number of atoms in the sample, we need to first calculate the number of moles of nickel present in the sample using its molar mass. The molar mass of nickel is 58.69 g/mol. Dividing the mass of the sample by the molar mass gives us 0.200 moles of nickel. Finally, multiplying this by Avogadro's number (6.022 x 10^23 atoms/mol) gives us approximately 1.20 x 10^23 atoms in the sample.

The element with an atomic mass of 35.453 is chlorine. It is a halogen and has the atomic number 17.

Sulfur symbol is S, and its atomic mass is 32.

actually the atomic mass is the same as the amount of protons so if you want to be lazy here are the atomic number (in which is 47 also the same as the atomic mass) and the atomic mass 47, and the number of protons 47.

The atomic mass of carbon dioxide (CO2) is 44.01 grams per mole. This value is calculated by adding the atomic masses of one carbon atom (12.01 g/mol) and two oxygen atoms (16.00 g/mol each) together.

Zerconium is a metal element. Atomic mass of it is 91.

No, the valance electrons determine the charge, the atomic number is determined by the number of protons. Generally, electrons are equal to protons, but in ions it is different, so use protons.

so the mass of an atom is determined by the number of protons and neutrons in an element. For a given element, the number of protons is the same but the number of neutrons can vary (an element can have various isotopes). Therefore, the average atomic mass of an element is simply a weighted average of the masses of all the isotopes of that element.

(a weighted average means that how common an isotope is is taken into account when incorporating it into the average, so rare isotopes will not count as much as common isotopes)

Please see the Periodic Table of Elements.

Mass is a fundamental concept in physics, roughly corresponding to the intuitive idea of how much matter there is in an object. Mass is a central concept of classical mechanics and related subjects, and there are several definitions of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.

In everyday usage, mass is more commonly referred to as weight, but in physics and engineering, weight means the strength of the gravitational pull on the object; that is, how heavy it is, measured in units of force. In everyday situations, the weight of an object is proportional to its mass, which usually makes it unproblematic to use the same word for both concepts. However, the distinction between mass and weight becomes important for measurements with a precision better than a few percent (due to slight differences in the strength of the Earth's gravitational field at different places), and for places far from the surface of the Earth, such as in space or on other planets.

Antoine Lavoisier - developed the Law of Conservation of Mass.

Sorry no where does it inidcate who discovered the term "mass".

Hope my info helps

The atomic mass of an atom with 11 protons and 12 neutrons is calculated by adding the number of protons and neutrons together. In this case, the atomic mass would be 11 (protons) + 12 (neutrons) = 23 atomic mass units.

Scientists use the symbol "u" to represent atomic mass unit.

Cadmium is a metal element. Atomic mass of it is 112.

In 1803 Dalton suggested 1H as the basic unit for the atomic mass unit(amu). Ostwald recommended 1/16 mass of Oxygen. However, this suggestion was made before the isotopes 17O an 18O were discovered. Since 1961, the unit is based on 1/12 mass of 12C.

The scientific unit of mass is the kilogram, symbolized as "kg." It is defined as the mass of the international prototype of the kilogram, a platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France.

The relative atomic mass of chlorine is 35.5. The two main isotopes are chlorine-35 and chlorine-37.
