Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
What nuclide is used as the standard in the relative scale for atomic masses and What is it's assigned atomic mass?
Carbon 12
What is the standard for atomic mass unit called?
One twelfth (1/12) the mass of a carbon-12 atom is one atomic mass unit (amu, or just u).
What is Atomic Mass unit based on?
The mass of any isotope is based on the mass of an isotope of carbon, which is assigned a mass of 12.

What is carbon's atomic mass?
Carbon's atomic mass is ~12.0107. All of those decimals at the end tell us that there is more than one isotope of carbon. If you round the number, you will find the most common isotope of carbon. (Carbon12)IUPAC recommend in this case the expression atomic weight, not atomic mass.The atomic weight of carbon (IUPAC Table, 2009) is [12,0096; 12,0116]. This mean that the atomic weight is variable between the above mentioned limits, depending on the type of the sample.
What is the name of the two numbers assigned to every element on the periodic table?
Atomic number (protons) and atomic mass (not to be confused with atomic weight, even if the difference is slight)
How much atomic mass unit 1 g substance has?
Atomic mass is not a measure assigned to gross mass such as grams, kilograms, pounds, stones, tons etc.Atomic mass of an element is determined by the number of protons there are in the nucleus of that element.The amu (atomic mass unit) is standardized as 1/12 of the mass of an atom of Carbon
How many electrons does silicon -28 have?
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The Atomic Mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)
How do you find the atomic weight on the periodic table?
On many Periodic Tables, the small number directly below the chemical symbol is the atomic mass. On mine, there is a small 12.011 under the large C for carbon. While most carbon is 12, there are naturally occurring carbon13 and carbon14, so this is an average mass of all naturally occurring isotopes, with the majority of isotopes being carbon12
