How many electrons are in the outermost electron shell of the halogens? a. {eq}2 {/eq}. b. {eq}5 {/eq}. c. {eq}1 {/eq}. d. {eq}7 {/eq}. Halogens: The term halogen refers to a substance that creates salt when reacted with metals. Fluori...
Note:The K shell has one sub-shell (s), the L shell has two sub-shells (s, p), the M shell has three sub-shells (s, p, d), the N shell has four sub-shells (s, p, d, f). The valence electrons are the total number of electrons in the last shell combining all the sub...
Concept Introduction: Each electron in an atom is described by four different quantum numbers. The first three (n, l, m l ) specify the particular orbital of interest, and the fourth (m s ) specifies how many electrons can occupy that orbital. Principa...
<p>To understand how carbon shows a covalency of four despite having only two unpaired electrons in its valence shell, we can break down the explanation into several steps:</p><p><strong>Step 1: Understand the Electronic Configuration of Carbon</strong>
When one shell was filled, electrons were found at higher levels. Chemical properties were based on the number of electrons in the outermost shell. Elements with full outer shells do not react. Other elements take or give up electrons to get a full outer shell. ...
The electronic configuration of an atom is important because it determines many of its physical and chemical properties. For example: Valence electrons are in the outermost shell and affect how an atom bonds with others. Atoms gain or lose electrons to achieve eight valence electrons (or two for...
Magnesium is atomic number 12. That means it has 12 electrons and 12 protons. Now, how are the elections configured, and how many electrons are in the valence shell? The first two shells are full, the first with two electrons and the second with eight. All that is left are two electron...
