Match each atom to the corresponding number of electrons it will steal or give away.
Stella [2.4K]

Answer:

1. Fluorine (7 electrons) => c. steals 1 electron

2. Calcium (2 electrons) => a. gives away 2 electrons

3. Oxygen (6 electrons) => d. steals 2 electrons

4. Lithium (1 electron) => e. gives away 1 electron

5. Xenon (8 electrons) => b. neither gives away nor steals any electron

Explanation:

Given the following valence electrons of the atoms listed above, each atom can be matched to its corresponding number of electrons it can steal or give away as they form bonds and attain a stable state:

1. Fluorine (7 electrons) => this will steal 1 electron from another atom to attain a stable state when it comes to make the number of electrons 8.

2. Calcium with 2 valence electrons, will give away this 2 electrons in its outer shell to be stable and form bond with another atom that will accept these 2 electrons.

3. Oxygen with 2 valence electrons, will steal 2 electrons to make the electrons in its outer shell 8, as it bonds with another atom to become stable.

4. Lithium will give away 1 electron to become stable when it combines.

5. Xenon with 8 electrons in its outer shell is in a stable state and kind of inert. It doesn't need to receive or steal any electron from or to any other atom in this state.

Lipids and carbohydrates differ in which of the following fundamental respects?
Schach [20]

Answer:

Carbohydrates are hydrophilic  whereas Lipids are hydrophobic.

Explanation:

Carbohydrates can be most commonly understood as hydrates of carbons. They generally contain more than two carbon atoms and are easily soluble in water, thus giving them the characteristics of hydrophilic compounds. Sugar and glucose are some of the important examples of carbohydrates.

On the other hand, lipids comprise a polar region, which attracts water and a much larger non-polar region, which repels water. This non-polar region dominates the polar region of lipid molecules thus making it a hydrophobic compound. Oils, fatty substances, steroids, and waxes are some of the important examples of Lipid molecules.
