Answer:
Option (d) chlorine has a greater ionization energy than sodium
Explanation:
Ionization energy is the energy required to remove an electron from a gaseous atom or ion. Sodium has just 1 electron in it's outmost shell and chlorine has 7.
Sodium needs 7 electrons to complete it's octet configuration and chlorine needs just 1.
Sodium can not attract 7 electrons to complete it's octet configuration instead it will easily lose the 1 electron in it's outmost shell to form cation. On the other hand, it will be difficult for chlorine to lose any of it's outmost electrons. This makes chlorine to have higher ionization energy than sodium.
I definitly believe the answer is c. 2
Surface tension. Im not sure if this is completely right but I hope I helped :)
Answer:
basic in nature
Explanation:
Litmus Test -
It is the very basic test , used to determine if the solution is acidic in nature or is basic in nature .
There are two type of litmus paper available , i.e. , blue and red .
- If the solution is acidic in nature ,
putting a blue litmus paper turns red ,
and putting a red litmus paper would not show any change .
And , hence it can be concluded that the solution is acidic in nature .
Similarly ,
- If the solution is basic in nature ,
putting a red litmus paper turn blue ,
and putting a blue litmus paper would not show any change .
And , hence it can be concluded that the solution is basic in nature .
The answer is D. Ne, which stands for Neon.
