<span>Since chlorine favours a (-1) oxidation state, it forms an ionic bond with group one metals with the formula XCl. All group one metals react vigorously with chlorine gas; and each reaction gets more violent as you move down Group 1 and produces a white crystalline salt. The reaction with chlorine is as follows 2X + Cl2 which gives 2XCl. Where X is an Alkali metal.</span>
Answer: LOL. I think thats how-
There are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles in the substance by its molecular mass.
However, given that the number of molecules in calcium hydroxide is 4.07 x 10¹⁵molecules, we need to calculate the number of moles in Ca(OH)2 as follows:
no. of moles of Ca(OH)2 = 4.07 x 10¹⁵ ÷ 6.02 × 10²³
no. of moles = 0.676 × 10-⁸
no. of moles = 6.76 × 10-⁹ moles.
Molar mass of Ca(OH)2 = 74.093 g/mol
Mass of Ca(OH)2 = 74.093 × 6.76 × 10-⁹ moles
Mass = 5.01 × 10-⁷grams.
Therefore, there are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.

Answer: Option (d) is the correct answer.
Explanation:
Metals are the species which contain more number of electrons.
When a specie loses electrons then it acquires a positive charge. Whereas when an atom gains electrons then it acquires a negative charge.
Thus, as metals have more number of electrons, therefore, in order to gain stability metals readily lose electrons.
Hence, metals naturally form positive ions, by losing electrons to empty the valence shell.
