3 days ago · Note: In this question we assumed the charge of the proton as $ + {\text{e}}$ and the mass of the proton as ${\text{m}}$ therefore the charge of the alpha particle is $ + 2{\text{e}}$ and the mass of the alpha particle is $4{\text{m}}$, then we found the specific charge for both of them using the formula and after that we calculated that the ...
4 days ago · Now to calculate number of electron, proton and neutrons in 1 mole 16O−2 16 O − 2 ion, we will multiply number of electron, proton and neutrons in one 16O−2 16 O − 2 ion to Avogadro’s number i.e. 6.022x1023 6.022 x 10 23. Now the number of electron in one mole 16O−2 16 O − 2 ion = 10 x 6.022x1023 6.022 x 10 23. = 6.022x1024 6.022 ...
3 days ago · As we know that mass number= number of protons + number of neutrons. Hence, the number of neutrons will be = 14 - 7 = 7. - Hence, we can conclude that there are 7 electrons, 7 protons, and 7 neutrons that nitrogen-14 have and it isn’t an anion or cation. It is a neutral atom.
4 days ago · Rank the three subatomic particles in order of increasing mass: (a) neutron, (b) proton, (c) electron. ... 56 neutrons, and 43 protons, what is its approximate atomic ...
4 days ago · As mentioned earlier, a positron is a positive electron, which means that the charge on a positron is equal to that of an electron, but positive in charge, unlike an electron. The charge on an electron is −1.6 ×10−19 coulomb − 1.6 × 10 − 19 c o u l o m b. So, the charge on a positron will be just the same in magnitude but opposite in ...
5 days ago · The atom with atomic number 20 is calcium. Hence, the symbol for the atom having 20 protons and 22 neutrons is Ca. Note: The calcium atom has atomic number 20 that is the number of protons, while it has a mass number of 42, that represents the number of neutrons as, mass = protons + neutrons. So, neutrons = mass – protons, therefore, 42 ...
3 days ago · A proton is converted into a neutron or vice versa within the nucleus of a radioactive sample in beta decay. This and alpha decay allow the nucleus of a radioactive sample to get as close to the ideal neutron/proton ratio as possible. The nucleus produces a beta particle, which can be an electron or a positron, as a result of this process.
