The archs to move through _ a _ _ o _​

Answer:

1.alkali metals are never found in nature uncombined because they are unstable and they react fast to other elements easily by losing the electron. They bond well with all elements except the noble gases. When these elements are in the air, they quickly turn black.

Therefore, we can conclude that alkali metals are highly reactive chemically and do not exist in a free or native state and are not easily found in nature.

2. Diagonal relationship between Lithium and Magnesium

Lithium shows a diagonal relationship with Magnesium.

Due to its small size lithium differs from other alkali metals but resembles magnesium, as its size is closer to lithium. The diagonal relationship is formed due to the identical size of ions.

As we move downward across a group in the periodic table then the size of the atoms gradually increases.

As we move towards right across a period in the periodic table, then the size of the atom reduces.

A diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods (first 20 elements) of the periodic table.

Answer:

When the dispersion medium is gas, the dispersed phase can be solid or liquid but not gas. Colloids of gas with dispersed phase as solids or liquids are called Aerosols. Fog is an example of an aerosol particle thus cloud or fog is a colloidal system in which the dispersed phase is liquid and dispersion medium is gas.
