The answer is (3)Ne. Usually, the elements belongs to group 18 all have completely filled valence electron shell. Among the four elements carbon, vanadium, neon and antimony, only neon belongs to group 18.

In the ground state, the atom that has a completely filled valence electron shell is NEON, Ne.

In the periodic table of elements, the elements that have completely filled valence electron shell are the noble gases and neon is one of them. The noble gases has eight electrons each in their outermost shells, this makes them to be stable and thus, they are unreactive in nature. The other elements in the periodic table usually undergo chemical reactions in order to have eight electrons in their outermost shells just like the noble gases.

In the naturally occurring D series of ketoses, the carbonyl group is found on carbon number ___________, whereas in aldoses, th
Elena-2011 [213]

Answer:

second carbon atom from the  end

end carbon atom

Explanation:

Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen. The general molecular formula of Carbohydrates is C_x(H_2O)_y.

Carbohydrates can be classified based on structures,

Carbohydrates with the structure of alkanals (-CHO) are known as aldose while those of the structure of alkanones (C=O) are known as ketose.

In stereochemistry , D series is a kind of configurational arrangement where the hydroxyl group attaches itself to the right hand side.

Thus; in naturally occurring D series of ketoses, the carbonyl group is found on carbon number <u>second carbon atom from the  end </u>whereas in aldoses, the carbonyl group is found on carbon number <u> end carbon atom.</u>

The reaction is a synthesis reaction.

<h3>What are synthesis reactions?</h3>

Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.

Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.

The different elements that combine are referred to as the reactants while the result of the combination is known as the product.

For example: A + B --> AB

In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.

This is a good example of a synthesis/combination reaction.
