Which of the following is possible for aluminum to have a full outer shell?i need the answer asap a. three electrons are lost, creating al-3. b. three electrons are lost, creating al+3. c. three electrons are gained, creating al-3. d. three electrons are gained, creating al+3.

The answer is; B.

This is called an aluminum cation. Aluminum forms bonds with anions in which it can donate its three valence electrons so it can achieve stable electron configuration. Stable electron configuration is having 8 electron in the outer shell. By donating its 3 outer valence electrons, the aluminium will have the more stable 2.8 electron configuration. The +3 means it has lost 3 electrons hence has 3 extra protons (that are not matched by an electron) in its nucleus (also indicating its valency).

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
