Three-quarters of the chlorine found in nature is chlorine-35, and the remaining quarter is chlorine-37. The formula used for the relative masses on the periodic table is: Relative atomic mass = (isotope 1 mass × isotope 1 abundance + isotope 2 mass × isotope 2 abundance + ...) ÷ ...
Give the reason why hydrogen can be placed in both group one and group seven of the Periodic Table? Why are the properties of alloys generally superior to their constituent components? Why do boron-10 and boron-11 exist in an abundance of 20% boron-10 and 80% boron-11?

I am looking to correct my understanding about the relative abundance of particles and antiparticles created before the two periods of annihilation: (1) protons/neutrons and anti-protons/anti-neutrons, and (2) electrons and positrons. In a previous thread... Buzz Bloom Thread Nov 21, 2015 Ta...
For synthetic elements, there is no natural isotope abundance. So, for these elements, the total nucleon count (sum of the number of protons and neutrons in the atomic nucleus) is usually cited in the place of the standard atomic weight. The value is given within brackets so that it's un...
Because waterfowl are an important economic resource, wildlife scientists study how waterfowl abundance is related to various environmental variables. In such a study, the variables shown in Table 1.15 were observed for a sample of 52 ponds. Table 1.15. Waterfowl data. OBSWATERVEGFOWL 1 1.00 0.00...
In total, 471 proteins were identified across all samples; 199 protein groups showed altered relative abundance by day of lactation (fold change ≥2, P < 0.05), but none were altered significantly by parity. Higher relative levels of immune proteins were found in colostrum, and milk fat ...
