  1. 4 days ago · Neutrons are represented as n n. A proton is said to be very stable whether it's in its free state or inside the atoms. They do not decay spontaneously. Electrons are stable. An atom is said to be stable if its outermost shell has electrons to complete the octet. They are unstable and decay liberating beta particles.

  2. 3 days ago · Note- The mass of the proton is about 1800 times more than the mass of the electron, in other words the proton is approximately 1800 times more massive than the electron. Its momentum (at the same speed) is 1800 times that of an electron and therefore the de-Broglie wavelength is 1800 times smaller than that of the electron.

  3. 5 days ago · According to the question, the distance covered by the electron while falling is-$ \Rightarrow S = 1.5cm \\ \\ \Rightarrow S = 1.5 \times {10^{ - 2}}m \\ $ As we know that-The mass of an electron is ${m_e} = 9.10 \times {10^{ - 31}}kg$ The mass of a proton is ${m_p} = 1.672 \times {10^{ - 27}}kg$

  4. 4 days ago · Hence, the electrostatic force of attraction between a proton and an electron in a hydrogen atom is $9.216 \times {10^{ - 8}}{\text{ N}}$ . Note: Although the magnitude of the charge on an electron and a proton is the same but their signs are opposite of each other. The charge on a proton is positive whereas the charge on an electron is negative.

  5. 2 days ago · -Electrons: The electron is a subatomic particle (denoted by symbol ‘${{e}^{-}}$ ’) and its electric charge is negative one elementary charge. It revolves around the nucleus of the atom and has a mass which is approximately $1/1836$ that of the proton. Both electrons and protons cancel each other's charge to maintain the balance.

  6. 3 days ago · After the removal of a charged electron from an atom, a charged particle called proton is made. These fast-paced protons from the anode rays. Hence the anode rays particles are called protons. These are positive charged particles. Therefore the correct answer is option (B). Note: It should be noted that hydrogen atoms are the lightest of all ...

  7. 5 days ago · As we know that mass number= number of protons + number of neutrons. Hence, the number of neutrons will be = 27 - 13 = 14. - Hence, we can conclude that there are 13 protons, 14 neutrons and 13 electrons are present in an atom of aluminium-27. Note: - We should note that the total number of neutrons present in the nucleus is equal to the ...
