Chemical nomenclature , replete as it is with compounds with complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics a fundamental resource will reveal not just the whimsical work of chemists , but the sometimes peculiar compound names that occur as the consequence of simple juxtaposition. Some names derive legitimately from their chemical makeup, from the geographic region where they may be found, the plant or animal species from which they are isolated or the name of the discoverer.

Privacy 13 methane CH4. Write formulas for the ionic compounds formed by the following ions.? Name each ionic compound. Part A. Thanks for visiting our site. Unformatted text preview: General Science Practice naming ionic compounds when given the formula.

Chemical compound names and formula can be very complex. Naming conventions vary by chemical compound type and involve Greek prefixes and knowledge of how chemicals react to one another. Below is a simplified guide on how to correctly write chemical names and formula in your research paper so you can get started! The primary function of chemical names is to be as specific as possible: the naming system is designed to ensure that there is no question what chemical compound is being referred to. Generally, the use of brand names should be avoided and generic names should be written instead. IUPAC rules are the most commonly used worldwide. Let us examine some of the common issues scientists encounter with chemical nomenclature.

The formula of the ionic compound formed by lithium and nitrogen is this is the only stable nitride of an alkali metal B Li3N.

The empirical and molecular formulas discussed in the preceding section are precise and informative, but they have some disadvantages. First, they are inconvenient for routine verbal communication. In such cases, it is necessary for the compounds to have different names that distinguish among the possible arrangements. Many compounds, particularly those that have been known for a relatively long time, have more than one name: a common name sometimes several , and a systematic name, which is the name assigned by adhering to specific rules. Like the names of most elements, the common names of chemical compounds generally have historical origins, although they often appear to be unrelated to the compounds of interest.

Calcium bromide — CaBr2. Determine the formula of the following compounds: Aluminum oxide — Al2O3. Let us help you simplify your studying. Put the two names together, metal first and that's it - you've named a ternary ionic compound. Common compound names.

The atoms in all substances that contain multiple atoms are held together by electrostatic interactions—interactions between electrically charged particles such as protons and electrons. Electrostatic attraction between oppositely charged species positive and negative results in a force that causes them to move toward each other, like the attraction between opposite poles of two magnets. In contrast, electrostatic repulsion between two species with the same charge either both positive or both negative results in a force that causes them to repel each other, as do the same poles of two magnets.

If you keep an eye on the latest trend followed by SSC for General Awareness questions , you would notice that Science facts are covering major portions of it. To help you quickly take a look at List of Chemical Formulas and their Common Names , we are providing you in this article. To help you attempt the chemistry questions without any glitches, we are sharing with you a detailed list of Chemical Formulas and their Common Names. Chemical formulas are expressions which state the number and types of atoms present in a molecule of a substance. Before moving ahead have a look at the Chemical compounds.

In the GCSE exams, chemical formulae are often given to you in the question. Remember our top three tips for each type of compound… and writing chemical formulae will never be a problem again! First off, decide if the compound is covalent or ionic. Remember that covalent bonding happens when all the elements in a molecule are non-metals e. The name starts with the atom at the centre of the molecule, and then tells you how many of the other elements there are.

A chemical compound is a chemical substance composed of many identical molecules or molecular entities composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A chemical formula specifies the number of atoms of each element in a compound molecule, using the standard abbreviations for the chemical elements and numerical subscripts. For example, a water molecule has formula H 2 O indicating two hydrogen atoms bonded to one oxygen atom.


Ionic compound is represented by a formula unit, the lowest ratio of atoms in the compound. Page Naming Ionic Compounds. (positive metal ion +.

Think about what you call your friends. Some of your friends might have full names long names and a nickname short name. These are the words we use to tell others who or what we are referring to. Their full name is like the substances name and their nickname is like the substances formulae. Without these names your friends would have no idea which of them you are referring to. Chemical substances have names, just like people have names. This helps scientists to communicate efficiently.

Although we still cling on to a few of these names, most chemicals are now named systematically on the basis of their composition. Despite this, to a novice chemist, ammonia and sulfuric acid can be equally as ambiguous as spirit of hartshorn or oil of vitriol.

3.1: Types of Chemical Compounds and their Formulas

Со всех сторон его окружали высокие стены с узкими прорезями по всему периметру. Выхода. Судьба в это утро не была благосклонна к Беккеру.

Это за четыреста-то баксов. Я сказал ей, что даю пятьдесят, но она хотела. Ей надо было выкупить билет на самолет - если найдется свободное место перед вылетом. Беккер почувствовал, как кровь отхлынула от его лица. - Куда.

Танкадо имел основания ему верить. Стратмор замялся, не зная, что ответить. - Отключите ТРАНСТЕКСТ, - взмолилась Сьюзан.  - Мы нашли Северную Дакоту. Вызовите службу безопасности.

Этот волшебный вечер был шесть месяцев назад, до того как Дэвида неожиданно назначили главой факультета современных языков. С тех пор их отношения развивались с быстротой скольжения по склону горы. ГЛАВА 4 Потайная дверь издала сигнал, выведя Сьюзан из состояния печальной задумчивости.

Люди на подиуме с нетерпением ждали, когда на экране появится их бывший сослуживец Энсей Танкадо. Ускоренное проигрывание видеозаписи придавало изображению некоторую комичность. Вот Танкадо вышел на открытое место и залюбовался открывшимся перед ним зрелищем.

Это два разных элемента. Люди на подиуме перешептывались. - Уран и плутоний! - воскликнул Джабба, и в его голосе впервые послышались нотки надежды.

 - Пусть директор разбирается. Она посмотрела ему в. - Ты представляешь, что произойдет, если выйдет из строя система охлаждения ТРАНСТЕКСТА. Бринкерхофф пожал плечами и подошел к окну.

Сьюзан открыла рот, желая сказать, что она все понимает, но ее слова были заглушены внезапным пронзительным звуком. Тишина шифровалки взорвалась сигналом тревоги, доносившимся из служебного помещения ТРАНСТЕКСТА. Сьюзан и Стратмор в недоумении посмотрели друг на друга.
