Question

An Element X has been discovered. Element X forms an Xt ion and

Answer 1

Answer: The chemical symbol of the compound formed is $XCl$ or $NaCl$

Explanation:

An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).

The element losing electron (metal) forms a positive ion known as a cation while the element gaining electron (non-metal) forms a negative ion known as an anion.

Element X has the atomic number 11 which is sodium. The electronic configuration of it is $1s^22s^22p^63s^1$

This element will lose 1 electron to form $X^+$ ion of $Na^+$

Chlorine has the atomic number 17. The electronic configuration of it is $1s^22s^22p^63s^23p^5$

This element will gain 1 electron to form $Cl^-$ ion

When these two ions combine, they lead to the formation of an ionic compound having a chemical formula of $XCl$ or $NaCl$

Hence, the chemical symbol of the compound formed is $XCl$ or $NaCl$
