Question

multiple choice question
a covalent bond in which electrons are shared equally by both atoms is called a(n)______

nonpolar bond
ionic bond
polar bond
double bond

Explanation:

• Nonpolar bond: In a non - polar covalent bond, the electrons are shared equally between the two atoms. This occurs when the two atoms have the same electronegativity (e.g., \(H_2\), \(Cl_2\)).
• Ionic bond: An ionic bond is formed by the transfer of electrons from one atom to another, resulting in the formation of ions (e.g., \(NaCl\) where \(Na\) donates an electron to \(Cl\)).
• Polar bond: In a polar covalent bond, the electrons are shared unequally. One atom has a higher electronegativity and pulls the electron pair closer to itself (e.g., \(H_2O\) where \(O\) is more electronegative than \(H\)).
• Double bond: A double bond is a type of covalent bond where two pairs of electrons are shared between two atoms (e.g., \(O = O\) in \(O_2\)). It is about the number of electron pairs shared, not about equal or unequal sharing of electrons in the context of polarity.

Answer:

nonpolar bond
