Notice though, that they have the same atomic number, they have the same number of protons in the nucleus. Right, it's one proton in the nucleus. And that's important because if you change the number of protons, you're changing the element, and that's not what we're doing here...
How Moseley's work on atomic numbers shows that atomic number is a fundamental property of elements rather than atomic weight. View Solution Assertion: The atomic number of an element has a more fundamental property than its atomic mass. Rationale: The atomic number is equal to the number of ...
The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer processors, such as the recently announced Apple A12 Bionic chip and Huawei Kirin 980, use 7 nm processes with 6.9 billion transistors on a centimeter square chip. The limits are being pushed to ...
Mosley (1913) obtained the X-ray spectrum of different elements and found that the frequency nu of the lines in the spectrum is related with the atomic number (Z) of the element, as sqrt(nu) = a(Z-b) a,b are constants for any selected series of lines i
However, the conditions that need to be satisfied by the rows and columns of a unitary matrix, as well as the requirement that the determinant of the matrix should be +1, reduce the number to eight independent real parameters. These eight parameters lead to eight generators of the SU(3) ...
Considering that elemental combinations are infinite, and the number of new materials is still growing rapidly, the next interesting questions might be (1) what the ultraincompressible materials of the future are? (2) how to efficiently design and discover the ultraincompressible materials of the fu...
It summarizes what must hold for a statement about t to make sense. It is not the kind of expression that is true or false. For example, when we say 0∈ℕ, we are thinking that 0 is a natural number. This is a fact. We are thinking “0 is−a ℕ,” and it does not ...
If the technology works by destroying and reconstructing, there are a number of possible uses that are rarely used, like bodily restoration after injury or death, copying/mass-production of reconstructible objects, copying/mass-production of people, etc. Artificial Gravity: If your Cool Starship ha...

There are any number of grievances that can and have triggered military uprisings. There are any number of reasons or lessons from history wherein an industrious, hard-working group of close-knit people have taken a sharp turn in their external affairs to become a military threat. And there ...
