How many neutrons does mercury have? The most common isotope of uranium has 92 protons and 146 neutrons. … It has one proton and no neutrons. Some light materials such as boron will absorb neutrons while hydrogen will generally scatter neutrons, and many commonly used metals allow most neutrons to pass through them. Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. 78. Show … The only exception is hydrogen (H), which is made of one proton and one electron. The "2+" charge tells us that we have lost two electrons. They are a component of "heavy water" and are used in things like fusion research. How many protons does platinum have? So it's proton number will always be #1#.. A neutral hydrogen atom does not have any charge. The mass number, on the other hand, is a sum total of the number of protons and neutrons. For example, silicon has 14 protons and 14 neutrons. Hydrogen has NO neutrons. How many electrons does mercury have? Answer the following - Are isotopes atoms of the same element or different elements? The thing that makes the different forms of hydrogen different is the number of neutrons in the nucleus, which have no charge. Hydrogen-2 (deuterium) has 1 proton and the extremely rate hydrogen 3 (tritium) has 2 neutrons. If an isotope of ‘H’ has mass no. U just made my day . All elements have an equal number of protons and neutrons, so the atomic number is also the number of electrons. A hydrogen atom has an atomic number of #1#.. How many neutrons does platinum have? Solution for 1. 2.1 Electrons, Protons, Neutrons, and Atoms. 2. Deuterium is an isotope of hydrogen designated as hydrogen-2. CharlesF .
