1. Elements combine to form millions of A. metals.
B. mixtures
C. compounds.
2. The forces that hold atoms together in combinations are called
A. energy bonds.
B. nuclear bonds.
C. chemical bonds.
3. Every electron has a
A. neutral charge.
B. positive charge.
C. negative charge.
4. The exact positions of the electrons in an atom cannot be determined because
electrons are always
A. moving
B. sharing.
C. changing
5. Compared with electrons that are closer to the nucleus, those that are farther
away have
A. less energy
B. more energy
C. equal energy

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 previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

i believe the answer is three water molecules
