Valence electrons - Cadence

Japanese: 価電子 - カデンシ
Valence electrons - Cadence

Also called atomic valence electrons. These are electrons that are involved in electron pair bonds with other electrons. In general, chemical bonds are formed by two elements donating one electron each to share, so the valence electrons of an atom must be isolated, unpaired electrons. Therefore, the number of valence electrons is equal to the atomic valence of the element. [See alternative terms] Atomic valence state

Japanese:

原子価電子ともいう.他電子との間の電子対結合に関与している電子をいう.一般に,化学結合は互いに1個の電子をだしあって共有することにより形成されるから,原子の価電子は孤立した不対電子でなければならない.したがって,価電子の数はその元素の原子価と等しい.[別用語参照]原子価状態
