Selenium-79 is a radioisotope of selenium present in spent nuclear fuel and the wastes resulting from reprocessing this fuel. It is one of only 7 long-lived fission products. Its fission yield is low (about 0.04%), as it is near the lower end of the mass range for fission products. Its half-life has been variously reported as 650,000 years, 65,000 years, 1.13 million years, 480,000 years, 295,000 years, 377,000 years and most recently with best current precision, 327,000 years.

Selenium is a chemical element with atomic number 34 which means there are 34 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 . Selenium - Mass Number - Neutron Number - Se. Mass numbers of typical isotopes of Selenium are 74; 76; 77; 78; 80. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. . Gold is a chemical element with atomic number 79 which means there are 79 protons .
Bromine is a classified halogen and its symbol is ‘Br’. Bromine is the 35th element of the periodic table so its atomic number is 35. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a bromine atom has thirty-five protons and thirty-five electrons. The number of neutrons in an atom .
Selenium, atomic structure Identify the atom or ion that has 23 electrons, 26 protons, and 28 neutrons. Identify the atom or ion that has 28 electrons, 30 protons, and 35 neutrons. Identify the atom or ion that has 8 electrons, 8 protons, and 8 neutrons. Identify the atom or ion that has 18 electrons, 15 protons, and 16 neutrons.Conclusion. In conclusion, selenium has 34 protons, 34 electrons, and various numbers of neutrons depending on the isotope. It has unique chemical properties due to its atomic structure and is essential for human health. Selenium can also be toxic in high concentrations and can affect the environment. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) ( + 1) and a mass of 1 atomic mass unit (amu) ( amu), which is about 1.67 ×10−27 1.67 × 10 − 27 kilograms. Together with neutrons, they make up virtually all of the mass of an atom. An element must always have the same number of protons, however atoms of the same element can have different numbers of electrons (ions) or neutrons (isotopes). You can get the atomic number .Number of Protons: 34: Number of Neutrons: 45: Number of Electrons . Boiling Point: 684.9° C: Density: 4.79 grams per cubic centimeter: Normal Phase: Solid: Family: Nonmetals: Period: 4: Costs: $300 per pound . Common Compounds: Hydrogen selenide (H 2 Se) Sodium selenite (Na 2 SeO 3) Selenious acid (H 2 SeO 3) Selenium trioxide .First, to find the number of protons, we need to realize that the neutral atom had 53 electrons because it is the additional one electron that makes it a 1- anion. Now, because the atom has 53 electrons, it must also have 53 protons, and to find the number of neutrons we subtract this from the mass number. # n = A – # p = 127 – 53 = 74 .While protons and neutrons are located inside the nucleus at the center of the atom, electrons are located outside the nucleus in what is often called the electron cloud. Figure 4.4.1 4.4. 1: Electrons are much smaller than protons or neutrons. If an electron was the mass of a penny, a proton or a neutron would have the mass of a large bowling .
The charge of an atom is defined as follows: Atomic charge = number of protons − number of electrons (1.8.1) (1.8.1) Atomic charge = number of protons − number of electrons. As will be discussed in more detail later in this chapter, atoms (and molecules) typically acquire charge by gaining or losing electrons.
