Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If two or more atoms bond together by sharing unpaired electrons, and they equally share these electrons the bond between the atoms would be considered a ____ bond
A
Polar Covalent
B
Nonpolar Covalent
C
Ionic
D
H Bond
Explanation: 

Detailed explanation-1: -A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction. This occurs in gas molecules; also known as diatomic elements.

Detailed explanation-2: -A nonpolar covalent bond is a covalent bond in which the bonding electrons are shared equally between the two atoms.

Detailed explanation-3: -Although there are no hard and fast rules, the general rule is if the difference in electronegativities is less than about 0.4, the bond is considered nonpolar; if the difference is greater than 0.4, the bond is considered polar.

Detailed explanation-4: -The two atoms can share their unpaired electrons to make a covalent bond: In this molecule, the hydrogen atom does not have nonbonding electrons, while the fluorine atom has six nonbonding electrons (three lone electron pairs).
