What are the basic units of mass? What's the difference between atomic and mass numbers in an atom? From the atomic mass (mass number), one can deduce the number of ___ in each atom of an element. If an atom has 1 proton, no neutrons, and 1 electron, what element is it, what...
解答一 举报 An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12C.and NA=6.02*10^23therefore ... 解析看不懂?免费查看同类题视频解析查看解答 ...
The different forms of an element (same atomic number) with different mass numbers are called isotopes, and the atomic mass of an element depends on the abundance of each isotope. The products of fractional abundance and mass numbers of each ...

Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
Because protons are units of matter, atomic numbers are always whole numbers. At present, they range from 1 (the atomic number of hydrogen) to 118 (the number of the heaviest known element). As more elements are discovered, the maximum number will go higher. Theoretically, there is no maxi...
While weight is commonly measured in units like pounds (lbs) or newtons (N), density is expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). This reflects the different nature of these two quantities: weight as a force and density as...

The particle portion of the wave-particle duality involves how objects can be described as “quanta.” A quanta is the smallest discrete unit (such as a particle) of a natural phenomenon in a system where the units are in a bound state. For example, a quanta of electromagnetic radiation, ...
