Actually Rb or Rubidium in zero state has the following
electron configuration:
<span>1s22s2</span><span>2p6</span><span>3s2</span><span>3p63d10</span><span>4s2</span><span>4p65s1</span>
However we can see that the ion has a 1 positive charge,
which means that it lacks 1 electron, therefore the answer from the choices is:
<span>d.
rb+: 1s22s22p63s23p64s23d104p6</span>
Ionization energy, also called ionization potential, in chemistry, the amount of energy required to remove an electron from an isolated atom or molecule

Answer: The salt which has the highest pH is 
Explanation: Salts are formed by the reaction of acid and base. General equation for the generation of salt is given by:

The given salts are formed from the reaction of acids and bases.
1) 
This is a salt formed by the reaction of strong base (KOH) and strong acid
. So, this salt is a neutral salt.

2) 
This is a salt which is formed by the reaction of weak base
and strong acid
. So, this salt is an acidic salt.

3) 
This is a salt which is formed by the reaction of weak base
and strong acid (HCl). So, this salt is an acidic salt.

4) 
This is a salt which is formed by the reaction of strong base (NaOH) and weak acid
. So, this salt is a basic salt.

Now, we have to find the salt which has the highest pH value.
Highest pH value means that the salt must be basic in nature and from the given salts, only
is basic salt. Hence, this salt has the highest pH value.
