Does anyone know any online calculators where I can easily find out net ionic equations? Thanks :)

Explanation:

here are some websites that has it

but searching for "net ionic equation calculator" is a lot easier

hope this helps :]

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.  

it's c. elements are placed in rows based on how may valencies electrons have.
