Mathematical Constants

Copper (Cu) has a relative atomic mass because it is an average value that considers the different isotopes of copper and their abundance in nature. The relative atomic mass provides a more accurate representation of the average mass of an atom of copper compared to using just the mass number of the most abundant isotope.

Yes, atomic masses are typically measured in atomic mass units (amu), which are defined as one twelfth of the mass of an atom of carbon-12. This unit is convenient for expressing the masses of atoms because it allows for a more manageable scale of values compared to using the actual mass in kilograms or grams.

To find the average atomic mass of unobtanium-221, you would need to know the isotopic abundances of each isotope of unobtanium in nature. Then, you would calculate the weighted average of the isotopic masses based on their abundances. Without this specific information, the average atomic mass of unobtanium-221 cannot be determined.

Silicon has a Atomic Mass number (weight of protons and neutrons) of 28.09. Its actually 28.0855

The atomic mass of an element is the weighted average of the masses of its isotopes, taking into account their abundance. If the atomic mass of an element is 197.97, it represents the average mass of all naturally occurring isotopes of that element.

the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

*Avogadro's Constant is 6 x 10^23, representing the number of particles (ie. atoms/ions/molecules) in one mole of any substance :)

Tungsten is a metal element. Atomic mass of it is 184.

It has no diameter because it is a point particle (it has nothing inside it). It has mass because the mass has been measured experimentally. If this is hard to imagine, science has lots more concepts even harder.

Avogadro's number is represented as 6.022 x 10^23 and is a constant that represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. It is named after Italian scientist Amedeo Avogadro.

The element that has the closest mass to 89 is Yttrium(88.91).

Classical mechanics is the alternative to quantum mechanics. It is a branch of physics that describes the motion of macroscopic objects using principles established by Isaac Newton. Unlike quantum mechanics, classical mechanics assumes that objects have definite positions and velocities at all times.

The atomic mass of oxygen (O) is approximately 16 atomic mass units.

There is no "biggest" odd number as they continue infinitely. The largest odd number that can be represented in a finite way depends on the number system being used. In the decimal system, the largest odd number with a defined value would be 9.

The Atomic Mass is the total mass of all the sub atomic particles (i.e. the mass of the whole atom): Electrons, Neutrons and Protons.

Therefore, it identifies isotopes (as they have different number of sub atomic particales - even for the same element) and thus total mass differs.

There can be a fair amount of difference between the Atomic Mass of the most common isotope of an element and its Atomic Weight - which is averaged (weighted average). This makes a difference for single atom calculations, but makes little real difference in bulk calculations.

There are a few ways to determine the mass number, depending on what information you have about the isotope:

1. The mass number is calculated as the sum of an isotope's protons and neutrons.

2. The name of an isotope generally includes the mass number. For instance, carbon-14 has a mass number of 14.

3. The atomic mass (aka isotope mass or atomic weight) rounded to the nearest whole number is the mass number.

No, electrolyte levels can vary based on factors such as hydration status, diet, and certain medical conditions. It is important to maintain a balance of electrolytes in the body for proper functioning of muscles and nerves.

It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".

Joseph Louis Proust (1754-1826), In 1799 Proust stated that "Compounds always contain the same elements in a constant proportion by mass." This statement is now called law of definite composition or the law of constant proportion.

oxygen->16

ozone=3 atoms of oxygen

Therefore, atomic mass of ozone=16X3

=48u

please rate.........

Chlorine naturally occurs with mixed isotopes, and the number is an average of the atomic mass of those isotopes, in the proportion they are present.

The isotopes have the same atomic number (protons), but their mass number can be different due to the presence of a different number of neutrons. These atoms of an element having a different number of neutrons are called isotopes.

Avogadro's number is the number of particles (atoms, molecules, ions, etc.) in one mole of a substance, which is approximately 6.022 x 10^23. Therefore, 1 mole of any substance contains Avogadro's number of representative particles.

The value of the gas constant, denoted as R, is approximately 8.314 J/(mol·K) when expressed in SI units. It is a fundamental physical constant that relates energy, temperature, and the quantity of a substance in a system.

47 neutron and 36 proton and 36 electron because its atomic number is 36.
