What nuclide is used as standard relative scale for atomic masses?
12 grams of carbon-12 isotope.
This element was assigned relative atomic mass of one because it is the lightest element?
hydrogen
How do you determine the number of protons in a nuclide?
The number of protons in a nuclide is the atomic number for that element on the periodic table.
What is the nucleus of an isotope with a certain atomic mass and number?
Nuclide
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.

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 is an atomic species, having a defined number of protons, neutrons and also electrons on the orbit.
The element was assigned a relative atomic mass of one because it is the lightest element?
Hydrogen.

How are the atomic number and mass number of a nuclide affected by the emisson of gramma radiation?
Any change of the atomic number.
What radioactive decay processes do not reduce the atomic number of a nuclide?
Beta Decay.
What is the approximate atomic mass of a nuclide of phosphorus that an atomic number of 15 and that has 16 neutrons?
The atomic mass of phosphorous-31 is 30,97376163(20).
What does the relative atomic mass of an element tell us about the relative abundance of an isotope?
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
