WebBromine is a chemical element with atomic number 35 which means there are 35 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. WebDec 3, 2024 · To solve this problem we need to calculate the number of moles of CH₂Br₂ in 35.2 g. Now we use Avogadro's number to calculate the number of Br atoms in 0.2025 moles of CH₂Br₂, keeping in mind that there are 2 Br atoms for each CH₂Br₂ molecule: Because the symbol for bromine is Br and the make-up of the elements say that there are 2 ... howe siding austin mn
