Answer:-
[Kr] 5s1
Explanation:-
Atomic number of rubidium = 37
Atomic number of Kr = 36
So only 1 electron needs to be assigned an orbital.
Kr is also the last element of the fourth period
So the shell number for the 1 electron will be 5 since it is after Kr
Since s subshell is filled first the electron will go into 5s.
Hence the electron configuration for rubidium (Rb) in noble-gas notation is
[Kr] 5s1
Answer: Polarity is the dipole-dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule
An example is H2+ (SO4)2- in Tetraoxosulphate (VI) Acid
Explanation:
In the acid H2SO4, ionization results in the formation of a Positively charged hydrogen ion (2H+) and a negatively charged Sulphate ion (SO4)2-
The slightly positive and negative parts in the ACID generates the DIPOLE (two poles) and THUS explains polarity
D. Has a uniform composition and is only able to be separated by chemical means.
