Атом какого химического элемента содержит 79 электронов?
The element with 79 electrons is Gold, which is represented by the chemical symbol 'Au'. In the periodic table, Gold is located in period 6 and group 11, making it a transition metal. Its atomic number is 79, meaning it contains 79 protons and 79 electrons.
Gold has a total of 118 known isotopes, but only one is naturally occurring, which is the stable isotope 197Au. The other isotopes are radioactive and have very short half-lives.
The arrangement of electrons in an atom is determined by its electron configuration. In the case of Gold, the electron configuration is 281832181, which means its outermost shell (valence shell) has one electron. This makes Gold a very stable element, as most noble gases also have one electron in their valence shell.
Gold has many unique properties, such as its beautiful yellow color and high malleability. It is a highly valued precious metal in various industries, including jewelry, electronics, and medicine.
So, to answer your question, the atom of Gold contains 79 electrons.
