Which of the following describes the distribution of sodium and potassium between cells and body
fluids?

a) little of either in the cells, but large amounts of each in the body fluids
b) na+ mainly in the cells, k+ in the body fluids
c) k+ mainly in the cells, na+ in the body fluids
d) equal amounts of each ion in the cells and body fluids

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
