Atomic Mass

if you mean phosphorus then the atomic mass is 30.973762. i don't think phosphate is an element.

The atomic mass of an atom is calculated by adding the number of protons and neutrons. In this case, the atom has 28 protons and 34 neutrons, so the atomic mass would be 28 (protons) + 34 (neutrons) = 62.

Saturn is not the name of a chemical element and therefore does not have any atomic mass unit.

Atomic mass of an element is calculated based on the mass of it's protons and neutrons. This is why we get isotopes.

But I think you are talking about Carbon; the periodic table is based on 12.

If the atomic mass of elements in the periodic table increases, it means the number of protons and neutrons in the atomic nucleus has increased. This can affect the element's chemical properties, such as reactivity and stability. Elements with higher atomic masses tend to be less common in nature and are often radioactive.

Iodine has a higher atomic number (53) because it has one more proton in its nucleus than tellurium (52). However, iodine's lower atomic mass compared to tellurium is due to differences in their isotopic composition. Isotopes of iodine with lower mass numbers are more abundant, leading to a lower average atomic mass for iodine compared to tellurium.

The atomic mass number of an atom, if the atom's mass number is approximately equal to 0.33 that of carbon-12, would be 4. If the question is about actual masses rather than mass numbers, the mass of a helium-4 atom is about 4.00260 atomic mass units, while the mass of a carbon-12 atom is, by definition, exactly 12.000..... atomic mass units.

The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994

Chlorine is a non metal element. Atomic mass of it is 35.45.

If your asking "how does the mass show there are isotopes", then the answer is this: Isotopes are found by using a mass spectrometer, and the abundance (percent amount) of each isotope is determined. Using this percent of abundance, the AVERAGE mass is reported on the periodic table. For example, if carbon 12 had mass of 12 and carbon 13 had mass of 13, but the percent abundance of 12 was 99% and the abundance of 13 was 1%, then the atomac mass would be

12*.99+13*.01=12.01

You can tell it has isotopes by seeing that the mass is a decimal and not a whole number. It is harder to tell with carbon, because it's only off by .01, but looking at chlorine it is more clear. Most isotope weights are very close to being whole numbers, like Cl35 mass is 34.98 and Cl37 is 36.97. But looking at Cl atomic weight, it is 35.45; the .45 tells you it is a average because the value lies between the whole numbers as a decimal. Cl is 35.45, which is an average of 35 and 37 that's 76% and 24% abundance respectively.

17 electrons - atomic mass 35.5 and atomic number 17

Elemental hydrogen and helium have atomic masses less than twice their atomic numbers.

The atomic mass of oxygen is approximately 16.00 atomic mass units.

A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.

All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.

Any "stable bound system" is stable because there is a "mass deficit" or "binding energy" that is surrendered to the Universe at large. It takes that much or more energy to break the system apart...

A mass spectrometer is an instrument that measures the atomic mass of atoms and molecules. It does this by ionizing the sample and then separating the ions based on their mass-to-charge ratio. The resulting mass spectrum provides information on the relative abundance of different isotopes present in the sample.

The atomic number of chlorine is 17, which indicates the number of protons in its nucleus. The atomic mass number of chlorine is about 35.5, which represents the average mass of its isotopes considering their relative abundances.

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.

(203 x 0.30) = 60.9

(205 x 0.70) = 143.5

60.9 + 143.5 = 204.4

The answer is 204.4 amu !

Yes, true: the mass of 1 proton is exactly the same as of 1 neutron: 1 a.m.u.

To find the mass defect, subtract the atomic mass of tritium (3.016049) from the sum of the masses of the individual particles (3 protons and 2 neutrons). To find the binding energy, use Einstein's equation E=mc^2, where m is the mass defect calculated earlier.
