Every neutral atom of a given element has the same number of what two subatomic particles? A. Protons and neutrons
B. Protons and electrons

B. Protons and Electrons

Explanation:

Protons have a positive charge and electrons have a negative charge. When an element contains the same number of both of those particles the charges will cancel out leaving the atom with a neutral charge, as neutrons already have a neutral charge.

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.
