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
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
You need to do it yourself you cant cheat.
1:2
For example, magnesium and chlorine form magnesium chloride, MgCl2.

I don't know but what i do know is that two metals combined form a strip of metal called Bimetallic.
False. When a metal reacts with a nonmetal an ionic bond is formed.
ionic = metal + nonmetal covalent = nonmetal + nonmetal So your compound is covalent because P (Phosphorus) is a nonmetal and O (oxygen) is a nonmetal.
Neptunium beryllide (NpBe3) is a solid chemical compound (not metal, nonmetal or metalloid).
None of the above. Thiamin is a compound and the terms metal, nonmetal and metalloid apply to elements.

A covalent bond is formed. A molecular compound is formed.
A covalent bond is formed. A molecular compound is formed.

There are ionic compounds which is a compound formed by a positive metal ion and a negative nonmetal ion. And there are convalent compounds which is a compound formed in which atoms share electrons.
It depends on the elements that are combining. if they are a metal and a nonmetal then it would be an ionic compound. If they are both nonmetals then it would be a molecular compound.
A salt could be formed by an alkali metal and a(n)
If the electrons are "stolen" from the metal by the nonmetal, an ionic bond is formed. If the electrons are shared between the metal and the nonmetal, a covalent bond is formed. If the electrons "resonate" between the metal and the nonmetal, a resonance bond is formed.
False. When a metal reacts with a nonmetal an ionic bond is formed.
ionic = metal + nonmetal covalent = nonmetal + nonmetal So your compound is covalent because P (Phosphorus) is a nonmetal and O (oxygen) is a nonmetal.
Chloride is a term used for salts. Chlorine is a chemical element, nonmetallic.
No. It is a compound of a metal and a nonmetal. Magnesium on its own is a metal.
