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.

Example: a calcium atom has 20 electrons, with two of these in its outer energy level. To become an ion, these 2 outermost electrons will be transferred to a non-metal (say, oxygen).

What charge results when specific elements become an ion?
Either it loose electron or gain and if loose then it get positive charge and if gain then be negatively charged ion
What is a positive and negative ion?
when an atom loose electron it become negative ion and when it gains electron it become positive ion
How does tellurium become an ion?

P3- ion (phosphide ion) is formed
What type of element loses an electron to become an ion?
Alkaline metals and hydrogen, all the elements in the first column of the Periodic Table.
What is the purpose of elements to lose or gain valence electrons to become an ion?
they want to become stable by having all of the valence filled they want to become stable by having all of the valence filled

Does aluminum become a negative ion before bonding yes or no?
No, aluminum does not become a negative ion; like all metals, it forms a positive ion.
How does arsenic atom become an ion?
Arsenic must gain 3 electrons to become the As-3 ion.

elements..., but fluoride is a polyatomic ion.
What does an atom become when it loses or gains electrons?
it becomes an ion
