The correct answer is option A.

According to octet rule, there is a tendency of the atoms to lose, share or gain electrons in order to complete their octet, the octet is the presence of 8 electron in the outermost shell. The sulphur has 6 valance electrons in its outer shell. The chlorine has 7 valance electrons in its outer shell. To complete the octet, the one chlorine atom shares 1 electron pair with the sulphur in SCl2.
The mass number, also known as an atomic mass number or nucleon number, refers to the total number of neutrons and protons (in a combination known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. However, while calculating the mass number, the small contribution of mass from electrons is ignored.
Mass number is equal to Number of protons + Number of neutrons
Mass number = 11 + 7 = 18.
Hence, the correct answer is 18.
Answer: Prokaryotes, archaea, protists, fungi, algae.
Explanation:I don’t think there are any single celled organisms that are today classified as animals. So basically I just left the animal kingdom out. Both metazoans and sponges are for the most part multicellular.
Answer:
Smooth muscles
Explanation:
Smooth muscles are controlled by the autonomic nervous system that is responsible for involuntary movements that you do not have to think about. Smooth muscles are found in walls of hollow organs such as as your gastrointernal tract and blood vessels. They are responsible for peristalsis during digestion, internal muscle contractions when urinating and for pushing a baby during child-birth.
