What is periodic table?</h3>
Periodic table is defined as a tabular approach of showing the items so that they appear in the same vertical column or group when their attributes are similar. Phosphorus is the oldest chemical element, and hassium is the newest. Please take note that, unlike in the Periodic system, the elements do not exhibit their natural relationships with one another.
The elements that make up group 17 of the periodic table are the halogens. They are nonmetals that are reactive, such as iodine, bromine, chlorine, and fluorine. Halogens are non-metals that are very reactive. These substances share a lot of characteristics with one another.
Thus, the electron configuration of alkali metals would then resemble those of group 17 of the periodic table in the compounds they form.

Answer : The equilibrium concentration of is, 1.0 M
Explanation : Given,
Equilibrium concentration of = 0.26 M
Volume of solution = 1.00 L
Equilibrium constant = 4.0
The balanced equilibrium reaction will be,
The expression of equilibrium constant for the reaction will be:
From the reaction we conclude that the concentration of and are equal.
Let the concentration of be 'X'.
So, concentration of = X
Now put all the values in this expression, we get :
Thus,
The concentration of at equilibrium = X = 1.0 M
The concentration of at equilibrium = X = 1.0 M
Explanation:
Balanced chemical reaction equation will be as follows.
In human body, the neutral iron changes into (aq) cation. There will be an oxidation-half reaction and a reduction-half reaction. Equations for this reaction are as follows.
Oxidation: 2Fe^{2+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + 2e^{-}[/tex] .... (1)
Reduction: ...... (2)
On adding both equation (1) and (2), the overall reaction equation will be as follows.
Therefore, neutral iron is a part of Heme - b group of Hemoglobin and in an aqueous solution it dissolutes as a part of Heme group. Hence, then it becomes an cation.
