Webthe ions have the electronic structure of a noble gas (group 0 element), with a full outer shell For elements in groups 1, 2 and 3, the number of electrons lost is the same as the group number.... WebTwo (or more elements) can share electrons so that each attains the electron configuration of the nearest noble gas. The alkali metals will lose an electron to resemble the next lowest noble gas; thus, all the alkali metals form +1 ions. K loses an electron so that it will have the same electron configuration as Ne. Since K loses one electron ...
How many electrons must be lost or gained by each of …
WebThe number of electrons which must be gain or lose by a l to acquire an electronic configuration identical to the neat noble gas should be determined. Concept Introduction: Octet rule: generally all atoms will lose, gain or share electrons to attain 8 valence electrons; the electronic configuration of the nearest noble element. WebApr 16, 2024 · Lithium, an alkali metal with three electrons, is also an exception to the octet rule. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons. There are two ways in which atoms can satisfy the octet rule. birds fighting video
Solved Part 6 Section 2.7 9) How many electrons must be …
WebAug 13, 2024 · Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what … WebJun 9, 2014 · [2,8]^(2+) A magnesium atom has atomic number 12, so 12 protons in the nucleus and therefore 12 electrons. These are arranged 2 in the innermost (n=1) shell, then 8 in the next (n=2) shell, and the last two in the n=3 shell. Therefore a magnesium atom is [2,8,2] The magnesium ion Mg^(2+) is formed when the magnesium atom loses the two … WebJun 15, 2015 · The explanation is simple: the story is that nice and smooth, when you have to loose one or two electrons. Things in the middle don't just lose 8 electrons or get 5 extra. Extra charge means extra energy: an ion with a large charge is actually getting unstable because of the coulomb energy. birds fighting snakes
