Answer:

just do it √ you can do it I no power

Answer 2

Answer:

Explanation

• The number of nucleons gives the total number of protons plus neutrons in the atom. The number of nucleons is always very close to the atomic weight of the atom (which is 15.9994 for Oxygen).

• In contrast, a nuclear isomer would be two nuclear species that have the same number of protons and neutrons, but the elements vary in energy state. An isobar is similar to an isotope or isotone in that it describes a different atomic nucleus with similarities.
• The mass number (symbol A, from the German word Atomgewicht [atomic weight]),[1] also called atomic mass number or nucleon number
• The elements in groups (vertical columns) of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. However, there are also other patterns in chemical properties on the periodic table. For example, as we move down a group, the metallic character of the atoms increases. Oxygen, at the top of group 16 (6A), is a colorless gas; in the middle of the group, selenium is a semiconducting solid; and, toward the bottom, polonium is a silver-grey solid that conducts electricity.
• Gallium atoms have 31 electrons and the electronic shell structure is [2, 8, 18, 3] with Atomic Term Symbol (Quantum Numbers) 2P1/2.
• In the modern periodic table, the elements are listed in order of increasing atomic number.  The atomic number is the number of protons in the nucleus of an atom.  The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).  The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element.
