Because all atoms are neutral, the number of protons and electrons in an atom must be equal. 因为所有的原子都是电中性的,因此质子数与电子数一定是相等的。 figure 4.15-0 Thus, once you know the atomic number of an element, you know the number of protons and the number of electrons an ato...
How To Calculate Polarity With some chemical knowledge, you can fairly easily guess if a molecule will be polar or not. Each atom will have a different level of electronegativity, or ability to attract electrons. Actually calculating the polarity of a molecule precisely, however, requires ...

We even split the atom into smaller pieces called subatomic particles. But what exactly is an atom? What is it made of? What does it look like? The pursuit of the structure of the atom has married many areas of chemistry and physics in perhaps one of the greatest contributions of modern...
Electron configuration shows how the electrons are arranged in an atom (starting with the electrons closest to the nucleus). What is the full electron configuration of a neutral sodium atom? (a) 1s^2 2s^2 2p^6 (b) 1s^2 2s^2 2p^6 3s^2 3s^4 (c) 1s^2 2s^2 2 ...
Atomic massis the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the ...
