An electron, being a point particle, by definition has a diameter of zero. This has no relation to its mass.
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
Protons are found in nucleus, as neutrons are also.
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
the electron is the smallest in terms of mass. 9.11E-31kg/electron 1.67E-27kg/neutron 1.67E-27kg/proton
Electron is the lightest sub atomic particle it is 1836 times less than as that of the mass of the proton it's mass is 9.1*10-31kg
Ans: 5
68.3lbs is 31kg
31 Kg is 31,000 grams
31kg = 68.343 pounds.
68.34lbs is 31kgs
An electron has a mass of 9.109 X 10-31 kg, approximately 1⁄1840 the mass of a proton. However, the term mass number doesn't apply to electrons, it applies to atomic nuclei. The mass number of a nuclear isotope is the total number of protons and neutrons, together known as nucleons, of the isotope, and is denoted by (A).
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
It is way smaller (9.11x10^-31kg) than a proton or neutron (1.67x10^-27kg)
1 electron has a charge of -1.602 x 10-19 Coulombs (remember electrons are negative charged and a mass of 9.1095 x 10-31 kg. So divide: (-1.602 x 10-19 coulombs per electron)/(9.1095 x 10-31 kg/electron) = -1.759 x 1011 coulombs per kilogram. Therefore, charge of 4.7 kg electrons = 4.7 x 1.759 x 10-19, i.e 8.2673 x 10-19 coulombs.
You can do it in 5 steps. Against the stone (S) weigh 1kg of Rice (1R) Move 1R to the same side as S and, against S+1R, weight 2R Move 2R to the same side as S and, against S+3R, weight 4R Move 4R to the same side as S and, against S+7R, weight 8R Move 8R to the same side as S and, against S+15R, weight 16R 15R + 16R = 31R.
