X in ionic compounds : Al₂X₃ is in the VIA class, Elements that absorb 2 electrons to achieve stability according to octet rules

X in ionic compounds XCO₃ is in group IIA,Elements that release 2 electrons to achieve stability according to octet rules

The noble gas element is a stable class of elements. The noble gas element is monatomic. Stability of noble gases is caused by an electron configuration that has a stable configuration of 8 (has 8 valence electrons) except He with a duplet configuration (has 2 valence electrons)

Other elements that do not yet have electron configurations such as noble gases will try to achieve their stability by forming bonds between elements.

This is generally called octet rule, using the principle of electron handover

In the Al₂X₃ compound, the ionization reaction that occurs is

Al₂X₃ -> 2Al³⁺ + 3X²⁻

From this equation shows that X ions absorb 2 electrons so that X²⁻ ions are formed

Elements that absorb 2 electrons to achieve stability according to octet rules are the VIA group

So that element X is in the VIA class

For example O with its electron configuration: 2 6 absorbs 2 electrons into 2 8 according to the electron configuration of the noble gas from Ne

In the XCO₃ compound, the ionization reaction that occurs is

XCO₃ ---> X²⁺ + CO₃ ²⁻

Here element X releases 2 electrons so that X²⁺ ions are formed

Elements that release 2 electrons to achieve stability according to octet rules are group IIA

So that element X is in group IIA

For example, Mg with an electron configuration of 2 8 2, releases 2 electrons into 2 8 according to the electron gas noble configuration of Ne
