A cell with an especially good FIT is like an extra-strong link in the chain, it is probably a waste of resources since it is the weakest links that determine the strength of the chain just as it is the cells w
For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...
Because an atom’s mass depends mainly on the number of protons and neutrons it contains, and because protons and neutrons have masses close to 1 amu, you might expect the atomic mass of an element to always be nearly a whole number. 原子的质量主要取决于质子数和中子数,质子与中子的质量都...
Understanding ionization energy is important because it reflects an element's ability to participate in some chemical reactions or form some compounds. If you must determine which element from a list has the highest ionization energy, find the elements' placements on the periodic table. Remember that...
“volatile,” meaning that they are easily vaporized by impacts and ion sputtering. Each element exists in the form of several isotopes. An isotope is a variation of the same element, that consists of the same number of protons but a slightly different number of neutrons. For instance, ...
Different isotopes of the same element (same element with different amounts of neutrons) do not have the same atomic mass. Carbon-13 has an atomic mass of 13 amu. Atomic weight, unlike the weight of an object, has nothing to do with the pull of gravity. It is a unitless value that ...
How to find the mass number of an isotope?What are Isotopes?Isotopes are different 'versions' of an element differing in the number of neutrons found in the nucleus. The atomic weight for an element is usually not an integer as it is the weighted averages of all the isotopes of that ...
One mole of any substance equals6.022∗1023quantities of that substance. A mole is a unit of counting similar to a dozen or stone etc. Answer and Explanation:1 Step 1: Determine the molar mass of the substance( say M). It is determined using the number of protons and neutrons in on...
Isotopes:Isotopes represent the same element. They are atoms that have the same number of protons but differ by the number of neutrons, and therefore differ by their total mass. Mass Spectrum:A mass spectrum is the readout of mass spectrometry. This shows peaks corresponding ...
How much would remain in the atmosphere, and how much would fall back to theEarth'ssurface? How much sunlight would such smokecloudsdeflect? During which season would the attack occur? If an attack occurred during the actual winter, might the results be far less severe?
