Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 x 10^-27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles calle
28、So we get at the number of neutrons indirectly because we know theprotonnumber here.(所以,我们可以间接得到中子数,因为我们知道质子数了。) 29、The researchers think these may be able to work asproton-exchange membranes in their own right.(研究者们认为这些“完全的膜”其本身就具有交换质子的...

IN 1933 Elsasser 1 pointed out that some of the properties of atomic nuclei correspond to greater stability for certain numbers of neutrons and protons (given the name magic numbers) than for other numbers; the magic numbers for both N (neutron number) and Z (proton number) are 2, 8, 20...
A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles pres...
Protons have arelative massof 1, which is the same as the relative mass of neutrons. Thenumber of protons in an atomis called the 'Atomic Number' of that atom and is sometimes referred to as 'Z'. This is important because itdefines the type of atom, i.e. whichelementit is an atom...

number, is different for every element (seeperiodic table). The mass of the proton is about 1,840 times the mass of the electron and slightly less than the mass of theneutron. The total number of nucleons, as protons and neutrons are collectively called, in any nucleus is the mass ...
