What does the roman numeral stand for when naming compounds?
The charge.
Why are there roman numerals in Compounds?
Its there too tell you the charge of the compound.
What is a nonpolar compound?
Polar compounds are those which have a net charged moment. Nonpolar compounds do not have a net charge, they are equal and neutral
What is a double-replacment?
A double replacment is a way of forming a new homogenous mixture. Generally double-replacement reactions involve the exchange of positive ions between two reacting compounds. Typically the compounds are in aqueous solution and are often characterized by the production of a precipitate. Explained: When dealing with two ionic compounds dissolved in water to form a homogenous mixture, there are two possiblities when they are mixed togeather. *They form a new homogenous mixture *A chemical reaction will occur,
Why is Roman numerals used in the names of compounds that contain transition metals?
Numbers are used to indicate the valency of the metal in the compound. By convention Roman numerals are used so that the number isn't mistakenly confused with the numbers present in the formula.
What do non metals and metals tend to do?
Metals and nonmetals tend to form ionic compounds by forming ionic bonds when they combine.
What is a property of metals?
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
Do metals receive electrons while forming their compounds?
Metals are more likely to donate electrons to form ionic compounds. However, some transition metals such as mercury and tin can form covalent bonds in which the metal shares an electron with another atom
What do electrons do to the charge of something?
they generally dont change charges, they are usually rearanged forming new compounds.
When forming a compound the chemical formula or compound is made stable with a net charge of zero by changing or adding?
When forming a compound the chemical formula or compound is made stable with a net charge of zero by the sharing of electrons (covalent compounds/molecules) or the transfer of electrons (ionic compounds).
What will be the charge for hydrogen when it becomes ions?
The ionic charge of a hydrogen ion can be -1 in compounds of hydrogen with very active metals such as sodium but will be +1 in most other compounds that contain hydrogen ions.
What happens to iron electrons in a chemical bond?
Iron atoms discharge electrons to form ions while forming compounds with non metals.
Which metals do not form compounds?
All metals can form chemical compounds.
What has a charge of plus 2 when forming ionic compounds?
Anything in the second column of the periodic table: beryllium, Magnesium, calcium, etc. AND many of the transitional metals (though they can also be 3+, 4+, or even more), commonly: iron, nickel, zinc, manganese.
What tend to lose electrons in order to become stable?
In chemistry, metals are the elements that tend to lose electrons when they react to form compounds; Non-metals tend to gain electrons when they form compounds. When metals and non-metals react and exchange electrons with one another they form an ionic bond.
Why are alkali metals not the alkaline-earth metals found uncombined in nature?
There are nothing uncombined. They are forming compounds inn nature.
What compounds are formed with the element of chlorine?
chlorine forms ionic compounds with metals and covalent compounds with non-metals.
