Look at the group number (the number along the top). Those in group I (Na, K, Li, etc) are 1+. Those in group II (Mg, Ca, etc) are 2+. Those in group III (Al, e.g.) are 3+.
The ionic charge of: alkali is +1 alkaline earth metals is +2 aluminium is +3
To recall the ionic charges of alkali metals, alkaline earth metals, and aluminum using the periodic table, note their group locations. Alkali metals (Group 1) typically have a +1 charge, alkaline earth metals (Group 2) have a +2 charge, and aluminum (found in Group 13) usually carries a +3 charge. These charges correspond to the number of electrons lost when these elements form cations. By remembering their group numbers, you can easily determine their common ionic charges.
This question is a little confused. The gram-atomic mass for aluminum is approximately 27 (look at a periodic table if you want more significant figures; I don't recall them off the top of my head). It doesn't matter if you have a mole or a planet-sized mass of the stuff, the gram-atomic mass is always going to be the same.
The term nucleon is applied to any particle that makes up an atomic nucleus. That means it can be applied to either a proton or a neutron (but only when we are talking about them as the components of an atomic nucleus). The nucleon with the positive charge is the proton. You'll recall that the neutron is a neutral particle; it has no charge.
Remembering
In the periodic table, alkali metals are located in group 1 and have a +1 ionic charge, while alkaline earth metals are in group 2 and have a +2 ionic charge. Aluminum is located in group 13 and typically has a +3 ionic charge. The group number can help you recall the typical ionic charge of these elements.
The ionic charge of: alkali is +1 alkaline earth metals is +2 aluminium is +3
Just look at the number of the family it is in, like alkali metals have a 1, alkaline earth metals have a 2, and aluminum has a 3. Then just put a plus sign in front of it and you have the charge of the ion.

The ionic charge depends on the number of valence electrons. Alkali metals, alkaline earth metals and aluminium have 1, 2 and 3 valence electrons respectively and will hence form ions with +1, +2 and +3 charges respectively.

No.
If a safety problem is discovered in a car, the car company must initiate a recall to fix the problem at no charge to consumers.

The 2002 Nissan Altima has one recall. The recall for this years make and model is that the air bags are defective. The air bags sensor does not work as expected. This is not a safety recall and dealerships must replace them free of charge.
