the most likely answer would be zinc
A krypton-85 atom consists of 36 protons, 49 neutrons, and 36 electrons. Protons and neutrons are located in the nucleus at the center of the atom, while electrons orbit around the nucleus in various energy levels or shells.
Krypton has an atomic number of 36.
One atom of (^{36}Cl) contains 20 neutrons. This can be calculated by subtracting the number of protons (which is 17 for chlorine) from the atomic mass number (36).
Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.
36 electrons, 36 protons, and 49 neutrons
The mass number of an atom is the sum of its protons and neutrons. Copper has an atomic number of 29, which means it has 29 protons in its nucleus. If it has 36 neutrons, then its mass number would be 29 (protons) + 36 (neutrons) = 65.
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.
For a zinc atom with a mass number of 66, the number of neutrons can be calculated by subtracting the atomic number (30 for zinc) from the mass number. Therefore, there are 36 neutrons in a zinc atom with a mass number of 66.
The number of neutrons is different for each isotope. Chlorine-35 has eighteen neutrons. Chlorine-36 has nineteen neutrons. Chlorine-37 has twenty neutrons. ....... etc.
An atom of Krypton-78 contains 36 protons and 42 neutrons. Krypton has an atomic number of 36, which corresponds to the number of protons. Subtracting the atomic number from the atomic mass gives the number of neutrons.
That is not enough information to answer the question, because you didn't specify whether the atom with 47 neutrons and 36 electrons has a net charge. If the atom is electrically neutral, then it has 36 protons to match the 36 electrons, but if it is an ion, it has more or fewer protons.Krypton-83 has 36 protons and 47 neutrons, and 36 electrons if it is electrically neutral.
This is the radioactive isotope bromine-78.
