![]() Element: Cl Atomic Number: 36 Mass Number: 37 of Protons Select 17 18 of Neutror 20 37 of Electrons: 18 Charge: 1+ Answer 1: 36 Answer 2: 17 Answer 3: 18 Answer 4: 1+ 1/4 pts Partial. Partial Question 33 Select the correct answer from the dropdown menu in each opening. Transition metals (transition elements) have atomic numbers as follows: Group 3 to Group 12 First transition series: 21 Sc to 30 Zn, Second transition series. Atomic number of chlorine 17 number of proto. ![]() The elements that are liquids at room temperature are Hg and Br. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Elements that are gases at room temperature 27 o C: H 2, He, N 2, O 2, Ne, Cl 2, Ar, Kr, Xe and Rn. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. When an organism dies, it stops taking in carbon-14, so the ratio of carbon-14 to carbon-12 in its remains, such as fossilized bones, will decline as carbon-14 decays gradually to nitrogen-14 2 ^2 2 squared. Chlorine is a chemical element with atomic number 17 which means there are 17 protons in its nucleus. As animals eat the plants, or eat other animals that ate plants, the concentrations of carbon-14 in their bodies will also match the atmospheric concentration. As plants pull carbon dioxide from the air to make sugars, the relative amount of carbon-14 in their tissues will be equal to the concentration of carbon-14 in the atmosphere. These forms of carbon are found in the atmosphere in relatively constant proportions, with carbon-12 as the major form at about 99%, carbon-13 as a minor form at about 1%, and carbon-14 present only in tiny amounts 1 ^1 1 start superscript, 1, end superscript. For example, carbon is normally present in the atmosphere in the form of gases like carbon dioxide, and it exists in three isotopic forms: carbon-12 and carbon-13, which are stable, and carbon-14, which is radioactive.
