Each aluminium ion should have a charge of +2, because the sum of oxidation numbers must be zero.
The uncharged aluminium atom must lose two electrons to become an ion with +2 charge.
what has to happen to an uncharged aluminum atom so that it will bond with oxygen?
It has to lose electrons to become positively charged, so it can attract a negatively charged oxygen ion
Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change .
Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt.
