Question

K and K^+ have different atomic number. State true or false. Justify your answer.

Answer 1

Dear student
It is a false statement .
K and k⁺ have same atomic number but different number of electrons.
If K is Potassium n then K has atomic number 19 and x number of electron. K⁺ has atomic number 19 but number of electrons is x-1 as it looses one electron i.e. negative charge and gains one positive charge.
