Which atom would tend to gain 1 valence electrons from another atom in order to become stable
Mrrafil [7]

Answer: Option (D) is the correct answer.

Explanation:

Atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.  

So, in order to attain stability it tends to gain one electron from a donor atom. Therefore, a chlorine ion is formed as Cl^{-1}.

As it gains only one electron that is why, -1 charge occurs.

Whereas Ar is a noble gas with atomic number 18. As it has completely filled octet so it will be unreactive in nature as it is already stable.

Similarly, He is also a noble gas so it is unreactive in nature.

Atomic number of boron (B) is 5 with electronic distribution 2, 3. So, in order to attain stability it needs to lose 3 electrons.

Thus, we can conclude that Cl is the atom which tends to gain 1 valence electron from another atom in order to become stable.

Butane is used as a fuel in disposable lighters. Write the Lewis structure for each isomer of butane.
AVprozaik [17]

Answer:

Lewis structure for isomers of butane has been given below.

Explanation:

Butane is a saturated alkane with molecular formula C_{4}H_{10}. Due to different positing of methyl groups, positional isomerism exists in butane.

Butane has two positional isomers with same molecular formula. One is n-butane and another one is isobutane. Lewis structures of these two isomers have been given below.
