Atoms form ions to increase their stability. For example consider sodium which has a single electron in its outermost shell. If it looses this electron it will have a complete octet in its outermost shell which is way more stable than a single electron in the outermost shell. So to increase their stability in a way that is energetically feasable, atoms usually form ions.
When an element becomes an ion, it can either gain or lose electrons. If it loses electrons, it becomes a positively charged ion (cation). If it gains electrons, it becomes a negatively charged ion (anion). The charge of an ion is determined by the number of electrons it has gained or lost.
Tellurium typically forms a 2- ion.
The oxygen family in Group 16 is most likely to become a -2 ion by gaining two electrons to achieve a full outer shell of eight electrons. This family includes elements like oxygen, sulfur, and selenium.

Some elements become ions by gaining or losing electrons to achieve a stable electron configuration. When an element gains electrons, it becomes a negative ion (anion), while losing electrons results in a positive ion (cation). This process allows the element to achieve a full outer electron shell and become more stable.
Alkaline metals and hydrogen, all the elements in the first column of the Periodic Table.
Cat-ion
Two elements that commonly form ionic compounds are sodium (Na) and chlorine (Cl). When they combine, sodium loses an electron to become a positively charged ion (Na+), while chlorine gains an electron to become a negatively charged ion (Cl-), forming the ionic compound sodium chloride (NaCl).

No, aluminum does not become a negative ion; like all metals, it forms a positive ion.

No, a polyatomic ion is a molecule composed of two or more atoms covalently bonded that carries a net charge. A molecule of dissimilar elements with a net charge is generally referred to as an ion, but not specifically as a polyatomic ion unless it contains multiple atoms of different elements.
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
