79-Br is more common because its abudance is 50.69%. 81-Br's abudance is 49.31% making it less common. Abudance is the rate at which the isotope is found in nature. In this case out of every 100 Bromine atoms you found 51 would be 79-Br and 41 would be 81-Br.
The isotope has 20 protons and 24 neutrons. This isotope is called calcium-44, and it is a stable isotope of calcium.
BromineThe number of protons in an element is always the same as the atomic number, which is 35 in this case. In a neutral atom (no charge), the number of electrons equals the number of protons, so it will be 35 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two isotopes of Bromine, 79Br and 81Br, having 44 neutrons and 46 neutrons respectively.See link below for more information on Bromine, as well as the related question below that will show you how to find the number of each subatomic particle in any atom.
Carbon-12 is more abundant on Earth than carbon-14. Carbon-12 is the most common and stable isotope of carbon, accounting for about 98.9% of all carbon atoms, while carbon-14 is a radioactive isotope with a much smaller abundance in the environment.
The hydrogen isotope with a mass of 3 is tritium. It consists of one proton and two neutrons, making it heavier than the more common hydrogen isotopes deuterium (mass 2) and protium (mass 1). Tritium is radioactive and is often used in nuclear reactions and research.
There are two isotopic kinds of HCl: hydrogen chloride (HCl) and deuterium chloride (DCl). Deuterium chloride is composed of deuterium, an isotope of hydrogen with one proton and one neutron in its nucleus, instead of the more common isotope of hydrogen with just one proton.

One way to write the isotope of bromine with 10 more neutrons than its atomic number is 81Br (atomic number 35 + 10 = 45 neutrons). Another way is to use the mass number notation and write it as bromine-81, where the mass number is the sum of protons and neutrons.
Oxygen-18 is a relatively rare isotope, making up about 0.2% of naturally occurring oxygen. It is often used in scientific research, such as studying climate history through ice cores or tracking the movement of water in the environment. Its rarity compared to the more common oxygen-16 isotope means that it can provide valuable insights in various fields.
Without additional information about the specific element in question, it's not possible to determine which isotope is more abundant solely based on the atomic masses. The abundance of isotopes depends on various factors such as stability and nuclear properties of the specific element.
Isotope A is more radioactive because it has a shorter half-life, indicating a faster rate of decay. A shorter half-life means that more of the isotope will undergo radioactive decay in a given time period compared to an isotope with a longer half-life.
The atomic number of Bromine is 35. That means the number of protons for the Bromine atom is 35 protons.The number of electrons in the Bromine atom is also 35.Bromine has two stable isotopes, 79Br (50.69%) and 81Br (49.31%). At least 23 radioisotopes are known. Accordingly, the number of neutrons for these two stable isotopes is respectively 44 and 46 neutrons.The isotopes of bromine range from 67Br to 98Br. That means the number of neutrons in a Bromine atom ranges from 32 to 63 neutrons.Refer to link below for more information.
Yes, 18O is an isotope of oxygen. It has a different number of neutrons compared to the more common isotope of oxygen (16O), which affects its atomic mass.
Aluminum has more neutrons than magnesium. The atomic number of aluminum is 13, which means it has 13 protons and typically 14 neutrons (in its most common isotope, aluminum-27). In contrast, magnesium has an atomic number of 12, with 12 protons and typically 12 neutrons (in its most common isotope, magnesium-24). Thus, aluminum has one more neutron than magnesium.
The isotope has 20 protons and 24 neutrons. This isotope is called calcium-44, and it is a stable isotope of calcium.
Lead-210 (Pb-210) is an isotope of lead where the atoms have 3 more neutrons than lead-207, which is the most common version of lead.
Heavy water has also been called deuterium oxide, D2O.
Carbon-13 is a stable isotope of carbon, meaning it has the same number of protons but a different number of neutrons compared to the more common isotope, carbon-12. It makes up about 1.1% of naturally occurring carbon and is often used in scientific research, such as in nuclear magnetic resonance (NMR) spectroscopy to study the structure of molecules.
