A template of a Venn diagram representing common and differentiating characteristics of covalent and ionic bonds is shown.
Which of the following characteristics can be written only in space A?

Formed between atoms of similar electronegativities
Formed between two metal atoms mostly found on the left of the periodic table
Formed between two non-metal atoms mostly found on the right of the periodic table
Formed between an atom that tends to lose electrons and an atom that tends to gain electrons

Formed between an atom that tends to lose electrons and an atom that tends to gain electrons

Explanation:

Exclusively, space A is made up of atoms that tends to lose electrons and an atom that leads to gain of electrons.

This is one of the unique properties of ionic or electrovalent bond.

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.
