When the outer electron shell is full in an element, this creates a Noble gas.
<u>Explanation</u>:
Noble gases are the elements that belong to group 18 in the periodic table. Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.
There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.
Answer:
Sphenoidal.
Explanation:
Water's method is a medical technique used for the production of the maxillary sinuses and facial bones. The 37 degree angle forms with the orbitomeatal line and the plane of image receptor.
Sphenoidal sinus group can be demonstrated with the patient as position for the parietoacanthal projection. The projection with CR is directed through when the patient's mouth is open.
Thus, the correct answer is option (D).
The functional groups that are bounded to the central carbon of every free amino acid monomers are CARBOXYL GROUP [COOH] AND AMINO GROUP [NH2].
A typical amino acid is made up of a central carbon which is attached to an amino group, a carboxyl group, a unique R group and a hydrogen atom.
