WebHelium is an element, so to make an element you have to combine protons and neutrons which is much much harder than it sounds. There are only 2 environments that commonly make elements. First is inside stars where the pressure and heat are unimaginably high that the protons and neutrons flu around in massive soup until they can stick to each other. WebHelium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom …
WebThere are two protons because the element is helium. There are no electrons because 2-2 = 0. There are 2 neutrons because 4-2=2. 35 Cl-17 protons, 18 neutrons, 18 electrons. …
WebHelium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. in wall speakers surround soundWebAn element with three stable isotopes has 82 protons.
