The question is incomplete, the elements to be arranged as required are shown in the image attached to this answer.
Answer:
K<Mg<P<O
Explanation:
Electronegativity is the ability of an atom of an element in a compound to attract the shared electrons of a bond towards itself. Atoms of highly electronegative elements tend to polarize a covalent bond leading to polar covalent bonds and dipole moments. Electronegativity increases across the period but decreases down the group hence the arrangement of elements in the answer provided above.

Answer:
An aqueous solution of will be an acid and have a pH of less than 7.
An aqueous solution of will be a neutral solution and have a pH equal to 7.
An aqueous solution of will be an base and have a pH of more than 7.
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.
Thus,
<u>An aqueous solution of will be an acid and have a pH of less than 7.</u>
<u>An aqueous solution of will be a neutral solution and have a pH equal to 7.</u>
<u>An aqueous solution of will be an base and have a pH of more than 7.</u>
