Each atom/element has an electron configuration
The electron configuration shows the energy level of the electron
Each electron configuration has 4 quantum numbers, namely n, l, ml, and ms
- n = the principal
- l = the angular momentum / azimuthal
- ml = the magnetic
- ms = the electron-spin
We make an example of the element Mg which is in group 2 with the atomic number 12
Electron configuration of Mg: [Ne] 3s² or 1s² 2s² 2p⁶ 3s²
if Mg removes 2 electrons then Mg will form a positive ion (cation) Mg²⁺
This cation is included in the monatomic ion because it is formed from one element (in contrast to the polyatomic ion, which is formed from two or more elements such as SO₄²⁻, ClO₃⁻)
Electron configuration of Mg²⁺ : 1s² 2s² 2p⁶
So atoms can be positively or negatively charged depending on removing or attracting electrons
Answer:
Protonation occurs at the carbonyl oxygen because the resulting conjugate acid is stabilized by resonance.
Explanation:
The carboxyl group is an organic and a functional group that consists of a carbon atom that's singly bonded to a hydroxyl group and double-bonded to an oxygen atom.
In the presence of strong acids, protonation occurs at the carbonyl oxygen because the resulting conjugate acid is stabilized by resonance.
The subgroup that comes after genus is species. It is often defined as the largest group of organisms in which two individuals are capable of reproducing fertile offspring, typically using sexual reproduction. Hope this answers the question. Have a nice day.
Answer:
A one-point pH change indicates the strength of the acid or base has increased or decreased tenfold; a 2-point change indicates a 100-fold change in acidity or alkalinity, and a 3-point change in pH indicates a 1000-fold change. Examples: • An increase in pH from 7.0 to 8.0 means the water is 10 times more basic.
