Answer:

Correct answer is B. Three electrons are gained, creating Al ^ -3

Explanation:

Aluminum in its valence shell has 3 electrons, this shell can have a maximun of 6 electrons. Then, to fill its valence shell, 3 electrons must be gained, and then the valence shell would have 6 electrons and would be complete.

If 3 electrons are gained, then Aluminum, would have a charge of -3, since each electron gained gives negative charge to the atom.

Al^ -3 is a ion of aluminum with charge -3.

Explain why pressure is not proportional to volume if the temperature changes?

Katen [24]

When temperature increases the particles of the substance move further away from each other and the substance expands, leading to an increase in volume. Since the particles are further away from each other pressure is reduced and that's why pressure is not proportional to volume when temperature changes.

Unless there is service it wifi, no. To access most features on a cellphone you need wifi or service. These features can include communicating with others or watching a video. Cellphones are practically useless without internet connection.
