Phosphorus Trichloride

Most polyatomic ions are oxyacid which means that the acid/compound contains oxygen

Mono is only used on the second element, if the first element has one atom it would not use prefix.

part 2 Common molecules

NaCl Sodium and chloride come together to form table salt which is used for everyday life also in mostly food.

CO2 One carbon and two oxygen come together to form carbon dioxide which is a harmful gas

Covalent bond

H20 2 hydrogen and one oxygen come together and form water which we use in everydaylife to stay hydrated, cook food, clean our body etc.

ionic compound

Chemical Namings

Ions

-Is a charged particle when the atom has gained or lost electrons -The formula for an atom losing or gaining electron is called ionic charge

For example The ionic charge for Lithium would be + 1 because there is one more proton than electrons The formula would be

Atoms

For example Lithium has 3 protons, 3 electrons and 4 neutrons

Is a subatomic particle that has an equal number of electrons and protons which makes it neutral

Criss-Cross method

The criss cross method does a simpler and easier way of writing the compound formula after understanding the concept.

Polyatomic ions

Binary acids

Binary acids are molecular compounds that is combined with the element hydrogen.

For example

Is a group of atoms with a charge

Multivalent ionic compound

Chemical names with transition metal have roman numeral numbers because it shows how much charge the atom has, since transition metals can have multiple charges.

Multivalent atoms are transition metals because they have more than one charge

Subtopic

These middle elements are called transition metals

Purple ones

Metals

metal ion

positive charge

Cation

a positively charged ion

Non-Metals

Non metal atoms

Non metal ion

negatively charged

Suffix

"-ide"

Only non metal atoms always have the suffix ending of ide at the end of every chemical name. (the suffix only applies to the non metallic atoms)

Anion

a negatively charged ion

Two non metals

Molecular compounds

formed with 2 or more non metals

Diatomics

these are molecules of only 2 atoms that can only be seen together

These diatmoic elements are only seen alone when they are in a a compound with another atom

Covalent bonds

Is a attraction that holds together 2 atoms which (only non metals

Prefixs

covalent compounds naming always starts with prefix in front on the element name to indicate how many atoms the compound consists of.

Ionic compound

Special cases

NO2 + H2O  HNO3

Simplifying equations

C6H12O6

CH6O

Harder compounds

Barium nitride

Nitrogen

-3 electron charge

-6 electron charge with 2 nitrogen atoms

Barium

Both barium and nitrogen should have he same amount of charge in order for the elements to react with each other

2 electron charge

6 electron charge with 3 barium atoms

now both have equal amount of charges where the compound consists of 3 bariums and 2 nitrogen

Br3N2

Also known as a binary ionic

A mixture of two things

Ionic bonds

Is a attraction that would hold a positive and negative charged ions together in a compound. It's a transfer of electrons from a metal to a non metal.

Is a chemical bond or compound that is formed by two or more ions that are held together (metal ions and non-metal ions)
