WebAug 14, 2024 · The octet rule doesn't actually say the highest shell should have eight electrons. It says that the atom achieves stability by gaining the electronic configuration … WebIn the progression thus far, three atoms—hydrogen, lithium, and sodium—have one electron in the outermost shell. As stated above, it is these outermost electrons that determine the chemical properties of an atom. Therefore, these three elements should have similar properties, as indeed they do.

Characteristics and Determination of Valence …

WebA sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. WebValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p … howard county jail inmate search

What number of electrons in the outer shell makes an element

WebEvery element in the first column (group one) has one electron in its outer shell. Every element in the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell. There are exceptions to the order when you look at the transition elements, but you get ... WebSimilarly, the atoms of all group 7 elements have similar chemical properties and reactions to each other, because they all have seven electrons in their outer shell. http://www.gcsescience.com/a3-electron-shell-energy-level.htm#:~:text=The%20maximum%20number%20of%20electrons%20in%20each%20shell%2C,that%20it%20will%20not%20react%20with%20other%20atoms. howard county iowa foundation grant
