Bonding between two elements of equal electronegativity would be

The given question is incomplete. The complete question is :

Bonding between two elements of equal electronegativity would be

a.100% covalent

b.50% ionic

c. metallic in character

d. primarily ionic

a. 100% covalent

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals. When the two non metals have equal electronegativities, the bond is called as non polar covalent.

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals.In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions.

your answer would be a. 12.5 kg
