WebJun 3, 2024 · How many electrons does oxygen-18 have? 18O2− has 8 protons, 10 neutrons, and 10 electrons. What is the total number of neutrons in an atom of O 18? For example, … WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be …
WebAtoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively. Valence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds. ... When oxygen combines with hydrogen, how many valence electrons does oxygen end up with? Question #56d50. WebApr 9, 2024 · rrange the atoms and/or ions in the following groups in order of decreasing size. msp;a.O,O,O2b.Fe2+,Ni2+,Zn2+c.Ca+,K+,Cl. Define valence shell and valence …
WebOxygen is the eighth element with a total of 8 electrons. In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. WebLet us determine the Lewis structures of SiH 4, CHO 2 −, NO +, and OF 2 as examples in following this procedure: Determine the total number of valence (outer shell) electrons in the molecule or ion. For a molecule, we add the number of valence electrons on each atom in the molecule: SiH 4 Si: 4 valence electrons/atom × 1 atom = 4 + H: 1 ...
