What do valence electrons have to do with bonding?

In terms of actual , there is literally only one example. You can consider that their oxidation states have never gotten higher than $+8$, except for Iridium: In terms...

Well, both magnesium and barium are $"alkaline earths...."$, the which give dications upon oxidation.... ...from Group 2 of . And given Group 2, there are TWO , which are readily...

Nitrogen is in Group V. It has 5 . Do I win £5-00?

And the zinc cation is $Zn^(2+)$. When the ions form a salt, clearly they form an electrically neutral species; and thus the formulation of the salt is $Zn_3P_2$. Each phosphorus...

We formally invoke a triple bond in $:C-=O$, a double bond in $O=O$, and a single bond in $Cl-Cl$. Given these representations, there are $6$, $4$, and $2$ electrons in...

Group 2 has two valance electrons. Group 18 would have 8 valance electrons. ( The 10 d electrons will drop down into the next lower shell and are...

The carbon atom has an electronic configuration of $1s^(2)2s^(2)2p^(2)$. The $2s$ and the $2p$ orbitals participate in ; a tetrahedral $sp^3$ hybridization scheme is commonly invoked in order to describe...

As a chalcogen, sulfur generally behaves as does oxygen. However, sulfur can form up to 6 covalent bonds: $SF_6$ is an example.

The for phosphorus is $1s^2 2s^2 2p^6 3s^2 3p^3$. The are usually the outermost s and p electrons and in this case, there are 2 3s electrons and 3 3p...

Look at the group number at the top of . The column number at the top is the group number. For example, the column with Be at the top is...
