WebDec 30, 2016 · An oxide ion has 8 protons and 10 electrons. Explanation: Oxygen has atomic number eight. This means that the nuclei of all oxygen atoms have eight protons. A neutral oxygen atom will also have eight electrons. In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10. WebFor any atom, stability is achieved by following the octet rule, which is to say all atoms (with a few exceptions) want 8 electrons in their outermost electron shell (just like noble gases). The electrons present in the outermost shell of an atom are called valence electrons. how do i put live wallpapers on opera gx

WebJun 2, 2024 · 30 - 2 = 28 electrons If the ion has a 1- charge (simply written with a minus superscript), then there are more electrons than the number of protons. For F -, the number of protons (from the periodic table) is 9 and the number of electrons is: 9 + 1 = 10 electrons Find the Number of Neutrons WebThe oxygen molecule (O2) has 16 electrons. In ground state (the most stable state of oxygen), the last two electrons of the oxygen molecule are located in a different π* antibonding orbital. These two unpaired electrons have the same quantum spin number (they have parallel spins) and qualify ground state oxygen to be a di radical. how do i put full screen on my computer
