10.So what EXACTLY is the cause of THREE different STATES of matter?
In your explanation you must use
words such as
Molecules or Atoms
Movement
Arrangement
Kinetic energy
Closely packed
Spread out

Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed molecules and atoms .A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.

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.
