Which of the following molecules would one expect to have a non-polar covalent bond?
Ivahew [28]

b. F₂ have a polar covalent bond

Explanation:

The type of bond depends on the difference of the electronegativity of the two elements.

if the electronegativity difference is under 0.4 the bond is non-polar covalent

if the electronegativity difference is between 0.4 and 1.7 the bond is polar covalent

if the electronegativity difference is greater 1.7 the bond is ionic

a. HCl

electronegativity of Cl - electronegativity of H = 3 - 2.2 = 0.8, so the bond is polar covalent

b. F₂

electronegativity of F - electronegativity of F = 4 - 4 = 0 , so the bond is non-polar covalent

c. HF

electronegativity of F - electronegativity of H = 4 - 2.2 = 1.8, in this case because non-metals are involved in the bond we consider this to be a polar covalent bond.

d. ClF

electronegativity of F - electronegativity of Cl = 4 - 3 = 1, so the bond is polar covalent

Based on the position of the elements in the periodic table, what is the charge of the ions they are most likely to form?
Rainbow [258]

Explanation:

The charge on an ion denotes the amount of electrons lost or gained or even shared by an atom.

An atom will lose, gain or share an equal amount of electrons that will make it stable and achieve an octet and perfect configuration.

This is often synonymous with the component number of electrons in their outermost shell. The valence shell.

For metals on the periodic table, they are always willing to give up electrons due to their large electropositivity.

Metals will give up the number of electrons in their outermost shell to become stable.

Groups 1 and Group 2 will have charges +1 and +2 on them.

For non-metals , they will gain the exact number of electrons that will make them stable.  We must note that half -filled and fully filled orbitals are equally stable.

Elements in groups 6 and 7 are electronegative and will have a charge of -2 and -1 respectively.

For those in groups 3, 4 and 5 they either gain, lose or share commensurate amount of electrons that will make them stable.

Group 8 elements are stable and have no charges.

Generally on the periodic table, metals are to the left and are always positively charged. Non - metals are to the right and are negatively charged.
