Atomic Mass

The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).

The atomic mass of a radioactive atoms is changed during the radioactive decay (alpha decay, neutron decay, proton decay, double proton decay), spontaneous or artificial fission, nuclear reactions.

The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.

The molar mass of tin is 118.7amu, 118.7 grams per mole

The average atomic mass of an element is calculated by considering the percentage abundance of each of its isotopes and multiplying it by the mass of each isotope. This calculation results in the weighted average mass of all the isotopes.

The atomic mass of honey is not a well-defined value as honey is a complex mixture of sugars, water, minerals, and other compounds. It does not have a single atomic mass like an element on the periodic table.

aright so lsn up bi**** and dumb a**** of all ages who cant answer this f****** simple question. you will fail if u dont knw it fa*****. all u do is 60.00 x 68.026 + 70.925 x 40.00... n whatver the f*** u get u divide it by 100!!! f***ing simple isnt it fa*****?

The atomic mass of strontium is not a whole number because it is an average value that takes into account the abundance of different isotopes of strontium in nature. These isotopes have different masses and occur in different proportions, resulting in a weighted average atomic mass that is not a whole number.

The atomic mass of a phosphorus (P) atom is approximately 31.0 atomic mass units.

First of all, the charge on most atoms is zero. A charged atom is called an ion, and is due to the atom gaining or losing electrons. I assume that you are referring to the charge and mass on the nucleus.

Every proton contributes charge and mass. Every neutron contributes only mass. Thus, there is a positive correlation between the two, but due to the fact that different atoms have diffirent isotopes, it is impossible to say, based on mass, what the charge is, or visa versa.

For example, most hydrogen nuclei are just single protons. Deuterium has a proton and neutron for a nucleus, and tritium has a proton and 2 neutrons. All of these nuclei have diffirent masses, but same charge.

The atomic mass listed on most periodic tables is actually the average atomic mass representing the average atomic masses of the various isotopes of an element depending on their percent natural abundance. Refer to the answers.com question: What is the formula for finding average atomic mass? for a detailed explanation on how to calculate this value.

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.

Magnesium (Mg) is part of the alkaline earth metals.

The chemical element with a relative atomic mass of 173 is Ytterbium (Yb).

The student who is determining the atomic mass of sodium is most likely conducting a chemistry experiment. They would be researching the atomic mass of sodium, which is approximately 22.99 grams per mole.

The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.

The atomic mass number of gadolinium is 157.25 g/mol.

The atomic mass is the mass in grams of one mole of the atoms concerned. Thus, 5 X 132.9 = 664.5 grams.

The atomic mass of the isotope 15N is 15,000 108 898 2(7).

The atomic mass listed in the periodic table is the weighted average of the masses of all the isotopes of an element, taking into account their abundance in nature. It is measured in atomic mass units (amu) and provides an average value that reflects the isotopic distribution of the element.

At the bottom, the atomic number is at the top.

For any element, the atomic number is the number of protons in the nucleus. And for any element, the atomic mass is the number of protons plus the number of neutrons in the nucleus. For an element with the atomic number 47 and an atomic weight of 107, it will have 107 - 47 neutrons in its nucleus, or 60 neutrons in its nucleus. Whether or not an atom is a neutral atom or not makes no difference here.

Molybdenum's atomic number is 42 and its atomic weight is 95.94

To determine the atomic mass of chlorine, you would need to know the relative abundances of its isotopes and their respective atomic masses. Chlorine has two stable isotopes: chlorine-35 and chlorine-37. By using the abundance of each isotope and their atomic masses, you can calculate the average atomic mass of chlorine.

Chlorine has no stable isotopes with a mass of 5. The atomic mass value listed for chlorine on the periodic table is an average of the masses of its isotopes, weighted by their natural abundance. As a result, the atomic mass of chlorine is not exactly 5 but rather around 35.5.
