What will the ratio of ions be from a group 1A metal and a group 7A non-metal?

Physical science

The 1A ions have +1 each,the 7A have -1 each.

Didn't we in 1990 get rid of those 1A etc groups, and went to I,II, III, roman numerials, as specified by IUPAC? http://en.wikipedia.org/wiki/Group_%28periodic_table%29

To determine the ratio of ions formed between a Group 1A metal and a Group 7A non-metal, we need to understand the principle of ion formation.

Group 1A metals, also known as alkali metals, have one electron in their outermost energy level (valence electron), while Group 7A non-metals, also known as halogens, have seven electrons in their outermost energy level (valence electrons).

When a Group 1A metal reacts with a Group 7A non-metal, the metal tends to lose one electron and form a +1 cation (positively charged ion), while the non-metal tends to gain one electron and form a -1 anion (negatively charged ion). This process occurs to achieve a stable electron configuration for both atoms.

To determine the ratio, we need to find the least common multiple between the charges of the cation and anion. Since the cation is +1 and the anion is -1, the least common multiple is 1.

Therefore, the ratio of ions formed between a Group 1A metal and a Group 7A non-metal is 1:1.
