The electrons can move freely within these molecular orbitals, and so each electron …
How many valence electrons does "Na" have? Socratic
WebSince the atomic number indicates both the number of protons and the number of electrons present in an atom, this isotope contains 19 protons and 19 electrons . The number of neutrons in the isotope can be calculated from its mass number, which is written as a superscript in a nuclear symbol. Mass Number = # of Protons + # of Neutrons WebJul 1, 2024 · On the left, a sodium atom has 11 electrons. On the right, the sodium ion only has 10 electrons and a 1+ charge. Now, let's consider chlorine atom, Cl: 1s22s22p63s23p5 Only one more electron is needed to achieve an octet in chlorine’s valence shell. When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. smart beds and nursing
