What nuclide is used as standard relative scale for atomic masses?
Carbon-12 is used as the standard relative scale for atomic masses. This is defined as having a mass of exactly 12 atomic mass units (u). Other elements are compared to this standard to determine their atomic masses.
This element was assigned relative atomic mass of one because it is the lightest element?
hydrogen
What nuclide is used as the standard in the relative scale for atomic mass?
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.
How do you determine the number of protons in a nuclide?
The number of protons in a nuclide is determined by its atomic number, which is unique to each element. The atomic number is typically listed in the periodic table and represents the number of protons in the nucleus of an atom.
What is a correct representation for a nuclide of radon?
A correct representation for a nuclide of radon in atomic symbol notation would be ^22286 Rn. This indicates that the nuclide has 222 nucleons (sum of protons and neutrons) and an atomic number of 86 (number of protons).

Standared for the atomic mass unit?
The standard a.m.u. is 1/12th of the mass of a Carbon 12 nuclide.

What is a nuclide symbol?
A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.
The carbon 12 atom is assigned a relative mass of exactly?
The carbon-12 atom is assigned a relative mass of exactly 12 atomic mass units (amu). This is used as the reference point for measuring the atomic masses of other elements on the periodic table.
What is nuclide writing?
Nuclide writing is a notation system used to represent a specific nuclide of an element. It includes the chemical symbol, atomic number, and mass number of the nuclide. This notation is helpful for identifying different isotopes of an element.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
How relative atomic mass of an atom can be determined?
The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø
