Atomic Mass

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.

As electrons have almost negligeable mass when compared to a proton, the mass of an atom mostly depends on the number of protons and neutrons in its nucleus. The mass of an electron is almost 1800 times smaller than the mass of a proton or neutron so in most calculations it can be safely assumed to be zero. In other words the mass of an atom depends on its atomic number.

The Order of Mass (Latin: Ordo Missae), also called the Ordinary of the Mass, is the set of texts of the Roman Rite Mass that are generally invariable. This contrasts with the proper, which are items of the Mass that change with the feast or following the Liturgical Year. ...

The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.

To determine the atomic mass of chlorine, you need to know the relative abundance of its isotopes (chlorine-35 and chlorine-37) and their respective atomic masses. By using the weighted average of these isotopes based on their abundance, you can calculate the atomic mass of chlorine.

Length of the edge , a = 290 pm =290 x 10-10 cm

Volume of unit cell = ( 290 x 10-10 cm )3 = 24.39 x 10-24 cm3

Since it is bcc arrangement,

Number of atoms in the unit cell, Z = 2

Atomic mass of the element = 50

Mass of the atom = atomic mass/ Avogadro number = M/No = 50/6.02 x 1023

Mass of the unit cell = Z x M/No = 2 x 50/6.02 x 1023 = 100/6.23 x 1023

Therefore , density = mass of unit cell / volume of unit cell

= 100/6.023 x 1023 x 24.39 x 10-24 = 6.81 g cm-3

An isotope with 35 neutrons and a charge of 2+ means it has 33 electrons (atomic number - charge). The atomic number can be calculated by subtracting the number of neutrons (mass number) from the relative atomic mass, so in this case, the atomic number is 30 (65 - 35).

That would Beryllium, with an atomic number of 4 and mass number of 9

Hope this helped!

The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.

No, the atomic number and atomic mass are different. Atomic number represents the number of protons in an atom's nucleus, while atomic mass is the average mass of an atom of an element, taking into account the number of protons and neutrons.

Atomic mass refers to the mass of an atom of a chemical element, which is the sum of the number of protons and neutrons in the nucleus. On the other hand, molecular mass refers to the sum of the atomic masses of all the atoms in a molecule, including the contributions from electrons. In general, atomic mass is specific to individual atoms, while molecular mass relates to groups of atoms bonded together.

You can either look at the element on a periodic table and the big number is the atomic mass or you can count how many protons are in one atom of the element. If something isn't an element, you can't easily or accurately find its atomic mass because it has an insane amount of atoms of different elements which you need a complex equation to combine into a reliable atomic mass. Even if you had and could use said equation, you would have to know the exact proportions of each element in the substance. That's why it's easier to use a periodic table for a pure element.
