I- number of electrons
WebElectrons are subatomic particles that hold an elementary charge of magnitude -1. The charge of an electron is equal in magnitude to the charge held by a proton (but has an opposite sign). Therefore, electrically neutral atoms/molecules must have an equal number of electrons and protons. Although the magnitude of the charges held by protons and ... WebAccording to Bohr’s formula, the fourth shell will have twenty-five electrons but the fourth shell of iodine will have eighteen electrons and the remaining seven electrons will be in …

WebStep-by-step solution. 100% (13 ratings) for this solution. Step 1 of 4. Atomic number of an element is equal to the number of protons and mass number is equal to sum of protons and neutrons. (a) As per the provided data, the atomic number is 5 and mass number is 10. Since atomic number is equal to number of protons so number of protons is 5. WebThe maximum number of electrons changes dramatically from one energy level to the next. The first energy level can contain 2 electrons, and the third and fourth levels can hold up to 18 and 32 electrons. Mathematicians would describe the increase as exponential. Scientists do not ordinarily apply this equation to levels higher than the fourth one.
WebOct 11, 2015 · Iodine, I, is located in period 5, group 17 of the periodic table, and has an atomic number equal to 53. That means that a neutral iodine atom will have a total of 53 … WebIn our example, krypton's mass number is 84 since its atomic weight, 83.80, rounds up to 84. The mass number is a count of the number of particles in an atom's nucleus. Remember that the nucleus is made up of protons and neutrons. So, if we want, we can write: Mass Number = (Number of Protons) + (Number of Neutrons) For krypton, this equation ...
WebA number of electrons are accelerated from rest through a potential difference V. They are then incident on a double slit setup with slit spacing d = 47.4nm. The m= 494 order … WebEach shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold …
WebApr 8, 2015 · The atoms have their electrons stripped by being fired through a carbon film, and their nuclear charge is then measured as a side effect of accelerating them. For a carbon nucleus we measure a charge of + 6, therefore a neutral carbon atom must have six electrons. Share Cite Improve this answer Follow answered Apr 7, 2015 at 17:45 John …
