What are hydrated salt?
An inorganic salt hydrate (hydrated salt or hydrate) is an ionic compound in which a number of water molecules are attracted by the ions and therefore enclosed within its crystal lattice. These water molecules may be referred to as water of crystallization or water of hydration.
Which halide exist as a hydrated salt?
LiCl or lithium chloride is formed hydrated salt.
Which element has highest hydration energy?
Lithium
Why are alkali metals not in Free State?
Alkali metals are the first group in the periodic table. They are never found in nature uncombined because they are unstable and they react fast to other elements. They bond well with all elements except the noble gases.
How can alkali metals be extracted?
Alkali metals are generally extracted by electrolysis of their ores. Only electrolytic method is suitable because of high reactive nature of alkali metals.
Why alkali metals are highly electropositive?
We know that alkali metals are highly electropositive, as they can readily lose an electron to reach the noble gas configuration. Since, caesium is an alkali metal, it has to lose only one electron. Hence, it is highly electropositive.
Why metals are highly electropositive in nature?
Metals are electropositive because they lose electrons and form positively charged ions. For example, Na, K ,Ca, Mg, loose electrons form positive charged ions so they are electropositive in nature.
Why elements of Group 1A and 2a are Electropositive?
Answer: The group 1A elements with their ns1 valence electron configurations are very active metals. They lose their valence electrons very readily. They have low ionization energies and react with nonmetals to form ionic solids.
What ionic charge does Group 2A have?
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges.
What is the name of the group 17 elements?
Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
