Question

question 1 2 pts match the type of bond associated with each description. terms may be used more than once. ionic choose covalent choose hydrogen choose a weak electrical attraction that holds individual water molecules together. a positively charged sodium ion is attracted to a negatively charged chloride ion to form table salt. an unequal sharing of electrons within an individual water molecule. carbon shares electrons with oxygen atoms in a carbon dioxide molecule. some structure in a protein molecule is due to weak electrical attractions. hydrogen choose

Explanation:

1. A weak electrical attraction that holds individual water molecules together is a hydrogen - bond. Hydrogen - bonds are intermolecular forces.
2. A positively charged sodium ion attracted to a negatively charged chloride ion to form table salt is an ionic bond. Ionic bonds occur between ions of opposite charges.
3. An unequal sharing of electrons within an individual water molecule is a polar covalent bond. In water, oxygen is more electronegative than hydrogen, leading to unequal electron - sharing.
4. Carbon sharing electrons with oxygen atoms in a carbon dioxide molecule is a covalent bond. In $CO_2$, carbon and oxygen share electrons to achieve stable electron configurations.
5. Some structure in a protein molecule due to weak electrical attractions is often due to hydrogen - bonds. Hydrogen - bonds contribute to the secondary and tertiary structure of proteins.

Answer:

1. hydrogen
2. ionic
3. covalent
