Question

All the statements are true about the formation of KBr except:
A: Potassium (K) belongs to Alkali metals.
B: Bromine (Br) forms anion.
C: Potassium atom lose two electrons.
D: Ionic bond has been formed.

Answer 1

Answer:

C option

Explanation:

Potassium does not lose two electrons because its oxidation state is +1

Answer 2

Answer :-

Option - C

EXPLANATION:-

Option - A :- Pottasium (K) belongs to Alkali metals

It is correct

Reason :-

As pottasium is a 1A group element So, We know that 1A group elements are called Alkali metals . Since Option A is correct

Option - B :- Bromine forms anion

It is correct

Reason :-

Bromine is a non - metaal So, it forms a anion that is" -1" It represents as Br - Since , Option- B is correct

Option- C :- Pottasium lose two electrons

It is incorrect

Reason :-

Pottasium lose only 1 electron as it is called valence electron .Because it needs to lose 1 electron to gain stable electronic configuration of Argon . So, it need to lose only 1 electron Since , Option - C is incorrect

Option - D :- Ionic form has been formed

It is correct

Reason :-

Ionic bond means two different that should one is cation and anion i.e

• Pottasium is a cation (+)
• Bromine is anion (-)

Since it forms the ionic bond Option- D is correct
