Aluminum loses 3 electrons. Since electrons have a negative charge losing them would make the aluminum atom lessnegative, which is positive. Hence, Al+3
Al ------> Al3+ + 3 e-
An aluminum ion
This charge is +3; the cation is Al3+.
The aluminium ion is Al(3+).
+3
there are 3 valence electrons in the atom of aluminum
Aluminum (Al) is in group 3A and so has 3 valence electrons. It can easily lose these to become Al^3+, so the charge would be +3.
Number of valence electrons depends on number of electrons in uncharged atom(= atomic number), not on mass number. Al has atomic number = 13 and it belongs to group 13( III A) of periodic table so it's uncharged atom has 3 valence electrons. But valence electrons in ions is different. No. of valence electrons in an ion = No. of valence electrons in uncharged atom + negative charge or - positive charge1. 1. for charges only their magnitude is taken i.e. if charge is +2 or -2 then 2 is taken and put in equation.
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
For an aluminium atom to gain a 3+ charge, it must lose its 3 outermost electrons; its valence electron. It then becomes an aluminium cation.
there are 3 valence electrons in the atom of aluminum
Because Aluminium has valence shell electronic configuration of 3s2 3p1 This indicates it has 3 valence electrons and so, it has to loose 3 electrons to gain stability, . Aluminum has 13 protons(+ve charge) and 13 electrons(-ve charge) and after poising 3 electrons it's net charge becomes 13 - 10 that is + 3 .
It would become an Aluminum ion that has a 3+ charge

the effective nuclear charge on barium is 2.

An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
Formal charge is used when creating the Lewis structure of a molecule, to determine the charge of a covalent bond. Formal charge is the difference between the valence electrons, unbound valence electrons, and half the shared electrons.
