WebSep 9, 2024 · Yes it has a mass and velocity but mass can be neglected as it very small as nucleus contain proton and neutron. And the mass of a proton is equal to the mass of a neutron. And the mass of a neutron or proton = 1800 times that of an electron. So nucleus is bigger than electron by 3600 times (As 2×1800) So electron have mass but very small … WebMar 30, 2024 · Question 3 Page 200 Calculate the number of electrons constituting one coulomb of charge.We know thatCharge on 1 Electron = 1.6 × 10−19 C1 Electron = 1.6 × 10−19 C 1.6 × 10−19 C = 1 Electron1 C = …
WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds. WebWhen there is an excess of electrons, the object is said to be negatively charged. When there are fewer electrons than the number of protons in nuclei, the object is said to be positively charged. When the number of …
