Group 2 elements have two valence electrons. Which kind of bond will they most likely form, and why?(1 point) Responses A covalent bond is likely because they want to share those two valence electrons in order to become stable. A covalent bond is likely because they want to share those two valence electrons in order to become stable. An ionic bond is likely because they will want to give away two valence electrons in order to become stable. An ionic bond is likely because they will want to give away two valence electrons in order to become stable. A metallic bond is likely because they are metals and can bond with other metals. A metallic bond is likely because they are metals and can bond with other metals. An ionic bond is likely because they are metals and will want to bond with nonmetals.

The correct response would be: An ionic bond is likely because they will want to give away two valence electrons in order to become stable.

Group 2 elements, also known as alkaline earth metals, have two valence electrons. To achieve a stable electron configuration, they tend to lose these two electrons, forming cations with a +2 charge, and typically bond with nonmetals that can accept those electrons, leading to the formation of ionic bonds.

Why is carbon so useful in molecules for living things?(1 point) Responses Many molecules in living things have millions of carbon atoms in them. Many molecules in living things have millions of carbon atoms in them. Carbon is produced in photosynthesis and carries the energy needed for life. Carbon is produced in photosynthesis and carries the energy needed for life. Carbon can form the backbone for millions of compounds found in living things. Carbon can form the backbone for millions of compounds found in living things. Carbon is produced in respiration, making it a readily available element.

The correct response is: Carbon can form the backbone for millions of compounds found in living things.

Carbon is unique in its ability to form stable covalent bonds with many elements, including itself, allowing the creation of a vast array of complex molecules. This versatility and ability to form different structures (such as chains, rings, and branches) make carbon a fundamental element in biological molecules, including carbohydrates, lipids, proteins, and nucleic acids.

Which structure defines the hydroxyl functional group?(1 point) Responses SH SH OH OH NH2 NH 2 CH3

The structure that defines the hydroxyl functional group is OH.

The hydroxyl group is characterized by a hydrogen atom bonded to an oxygen atom (-OH), and it is commonly found in alcohols.
