What will the ratio of ions be in any compound formed from a group 1a metal and a group 1a nonmetal?

Answer 1

The ratio will be 1:1. When they react chemically with one another, the group 1A metals (the alkali metals) give up one electron, forming ions with a charge of 1+, and the group 7A (17) halogens gain the electron given up by the metal, forming ions with a 1- charge. When they react chemically with one another, they form a neutral ionic compound with a ratio of 1alkali metal:1halogen.

Na+ + Cl- --> NaCl

Li+ + Br- --> LiBr

K+ + F- --> KF

Answer 2

The answer is NaCl. Sodium, Na, is from the Group 1A and Chlorine, Cl, is from the Group 7A.

A chemical formula is a notation that shows what elements a compound contains and the ration of the atoms or ions of these elements in the compound.The chemical formula for sodium chloride is NaCl. From the formula, you can tell that there is one sodium ion for each chloride ion in sodium chloride.

This is an example of how i understood the question:

A magnesium atom cannot reach a stable electron configuration by reacting with just one chlorine atom. It must transfer electrons to two chlorine atoms. After the transfer, the charge on the magnesium in is 2+ and its symbol is Mg2+ (the 2+ is supposed to be in the upper right corner). The formula for the compound is MgCl2 (the 2 is supposed to be in the lower right corner). The 2 written to the right and slightly below the symbol for chlorine is a subscript. Subscripts are used to show the relative numbers of atoms of the elements present. If there is only one atom of an element in the formula, no subscript is needed.

I got this information from the science book : Prentice Hall "Physical Science Concepts in Action" by Whysession, Frank, and Yancopoulos

Answer 3

You need to do it yourself you cant cheat.

Answer 4

1:2

For example, magnesium and chlorine form magnesium chloride, MgCl2.

Answer 5

The ratio of ions in a compound formed from a group 1A metal and a group 1A nonmetal will typically be 1:1, as both elements tend to form ions with a charge of +1.
