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.

Which cell organelle is shown by the diagram above?
tatiyna

Answer:

cell membrane

Explanation:

The cell membrane in the diagram consists of lipids, bilayers, and proteins. The lipids, located within the cell membrane, are known as hydrophobic, meaning they are afraid of water. In other words, the lipids keep out the water. Whereas the bilayer, otherwise known as the phospholipid bilayer, is attracted to water. While the proteins simply enable molecules and other microscopic parts travel within and out the cell membrane, through the protein.
