Writing and naming covalent compounds powerpoint

The following elements have only one possible charge, so it would be incorrect to put a Roman numeral after their name. She includes these "Go Fish Directions. If so, does it need a Roman numeral? Developing and using models because students learn to model the formation of covalent and metallic compounds.

Binary Covalent namingBinary Covalent NomenclatureThe purpose of this page is to describe the guidelines for constructing the names for binary covalent compounds, which are pure substances that consist of two nonmetallic elements.

A prefix will always be present on the name of the second element. Writing and naming covalent compounds powerpoint general formula is MaAb, with M representing the symbol of a metallic element, A representing the symbol for a nonmetallic element, and lowercase a and b representing subscripts in the formula unless one or more of the subscripts are assumed to be 1.

This is a copy of one student's filled in notes. Name tells you the formula. Everything you ever wanted to teach about hydrates! We do not write mono- at the beginning of a compounds name. Mono 1, di- 2, tri 3, tetra- 4, penta- 5, hexa- 6, hepta- 7, octa 8, nona- 9, deca - 10 prefix mono- is omitted for the 1st elementlast vowel of the prefix is dropped when the second element begins with a vowel Pentoxide The same prefixes are used to indicate the number of water molecules in hydrates Covalent vs.

Developing and using models Introduction In this lesson students delve into covalent bonding through taking notes and practicing with whiteboards and individual practice. Formula of ionic compound depends on the charges of the ions combinedIonic Compounds ContinuedThe total positive charge must equal the total negative charge because the number of electrons lost by one element or group of elements must equal the number gained by the other s.

If more than one polyatomic ion is needed, put it in parentheses, and place a subscript outside the parentheses. For the making molecules practice I have students use model kits. Try this " Chemical Compounds " wordsearch puzzle.

Drop the positive and negative signsCrisscross the superscripts so they become subscripts. There arent any since the two atoms share electrons, they do not take on a charge.

Classifying a compound is not an easy task, but for the purposes of naming them, we employ a simple test: Never use oxidation numbers to determine the formula. As students take notes there is an opportunity for students to perform practice questions. Metals lose all their valence electrons and become cations.

Subscripts are determined directly from the prefixes in the name. The name of N2O3 is dinitrogen trioxide. They also perform practice questions on slides 16 and 17 for covalent naming. Ionic Compounds Ionic bonds do NOT form moleculesChemical formulas for ionic compounds represent the simplest ratio of ion types Made of anions and cationsBinary ionic compounds contain only two different types elements.

Attach the selected prefix to the name of the first element in the formula. In fact, it is common for hydrogen atoms to be transferred from one ion or molecule to another ion or molecule.

WRITING AND NAMING IONIC COMPOUNDS - PowerPoint PPT Presentation

Which elements are involved in covalent compounds? Atoms combine to form individual molecules. We'll even convert your presentations and slide shows into the universal Flash format with all their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides.

Or have students bond with each other in their "Bond with a Classmate" activity that includes the cards. WarmUpWhat is necessary to write ionic compounds?

Metallic and Covalent Bonds- Formation and Naming

Engage Building on prior knowledge In this section of the lesson I engage students in the topic in two ways. Then write the name of the negative ion check the back of your PT to find namesFormulas: You can figure out what their charges are based on their names they will have roman numerals that indicate their charge.Chart and Diagram Slides for PowerPoint - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects.

Writing formulas and naming compounds

· Covalent bonds – sharing of electrons. The Octet Rule – Ionic Compounds. Ionic compounds form so that each atom, by. gaining or losing. electrons, has an octet of electrons in its highest occupied energy level.

Metals lose electrons to form positively-charged fmgm2018.com · Web view. · To name a covalent compound, you need the molecular formula, knowledge of the prefixes used for naming, and a way to look up the name of an element given its atomic symbol.
