Dalton's Atomic Theory explained a lot about matter, chemicals, and chemical reactions. If the universe had a net charge, then scientists should be able to measure their tendencies and effects on all electrical field lines in a way such that, instead of connecting from positive charges to negative charges, they would never end. For hydrogen, the number of protons is 1. For a circuit with voltage 3 V and resistance 5 that is applied for 10 seconds, the corresponding current that results is I = V / R = 3 V / 5 = 0.6 A, and the total charge would be Q = It = 0.6 A 10 s = 6 C. If you know the potential difference (V) in volts applied in a circuit and the work (W) in joules done over the period which it is applied, the charge in coulombs, Q = W / V. Electric field, the electric force per unit charge, spreads radially outward from positive charges towards negative charges and can be calculated with E = FE / q, in which FE is the electric force and q is the charge which produces the electric field. If you're not told the element name or its atomic number, it's hard to know the correct answer. This force of attraction keeps electrons constantly moving through the otherwise empty space around the nucleus. Direct link to Arushi Singla's post what mean is by integer m, Posted 5 years ago. How many electrons does it have? The net charge is the charge that there is more of in an object. Each element is defined by the number of protons found in each of its atoms.
