Which option describes the structure of the electron shells in a neutral carbon atom?(1 point) Responses The inner shell is complete with three electrons. The outer shell is incomplete with three electrons. The inner shell is complete with three electrons. The outer shell is incomplete with three electrons. The inner shell is complete with four electrons. The outer shell is incomplete with two electrons. The inner shell is complete with four electrons. The outer shell is incomplete with two electrons. The inner shell is incomplete with three electrons. The outer shell is incomplete with three electrons. The inner shell is incomplete with three electrons. The outer shell is incomplete with three electrons. The inner shell is complete with two electrons. The outer shell is incomplete with four electrons.

Answer 1

The correct option describing the structure of the electron shells in a neutral carbon atom is:

"The inner shell is complete with two electrons. The outer shell is incomplete with four electrons."

In a neutral carbon atom, which has an atomic number of 6, there are two electrons in the inner shell (first shell) and four electrons in the outer shell (second shell).

Answer 2

Which type of bonds can carbon atoms form with other carbon atoms?(1 point) Responses single, double, and triple bonds single, double, and triple bonds single and double bonds single and double bonds double and triple bonds double and triple bonds double, triple, and quadruple bonds

Answer 3

The correct response is:

single, double, and triple bonds.

Carbon atoms can form single (sigma), double (one sigma and one pi), and triple bonds (one sigma and two pi) with other carbon atoms.

Answer 4

Which structure defines the sulfhydryl functional group?(1 point) Responses SH SH OH OH SH2 SH 2 SOH

Answer 5

The structure that defines the sulfhydryl functional group is:

SH

This represents a sulfur atom bonded to a hydrogen atom, which is characteristic of the sulfhydryl (-SH) group.

Answer 6

Which option explains why this amino acid can act as both an acid and a base? (1 point) Responses It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can increase acidity, while the carboxyl group can decrease acidity. It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can increase acidity, while the carboxyl group can decrease acidity. It contains both an amino functional group and a methyl functional group. In a solution, the amino group can decrease acidity, while the methyl group can increase acidity. It contains both an amino functional group and a methyl functional group. In a solution, the amino group can decrease acidity, while the methyl group can increase acidity. It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can decrease acidity, while the carboxyl group can increase acidity. It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can decrease acidity, while the carboxyl group can increase acidity. It contains both an amino functional group and a methyl functional group. In a solution, the amino group can increase acidity, while the methyl group can decrease acidity.

Answer 7

The correct answer is:

It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can increase acidity, while the carboxyl group can decrease acidity.

However, to clarify: the amino group can accept a proton (acting as a base), while the carboxyl group can donate a proton (acting as an acid). This dual capability allows the amino acid to function as both an acid and a base.
