Identifyind ionic covalent and metallic compounds lab report

It has the same pattern of atoms as the diagram above, except that two colors are used to reperesent the carbon atoms. Ionic bonds are those in which a large difference in electronegativity exists between two bonding species.

A sodium chloride crystal, showing the rigid, highly organized structure. These each involve similar electrostatic interactions to the ones described in ionic and covalent bondsbut even those extensions are far from the end of the bonding story. That has now been transferred to a separate introduction to kinetic theory page in the physical chemistry section of Chemguide.

In reality even the most classic examples of ionic bondingsuch as the sodium chloride bondcontain characteristics of covalent bonding, or sharing of electrons of outer shell electrons.

Since phosphorus is the more metallic element left of sulfurit must be named first. You first name the confident metal ion, then you definately name the negative ion.

Steps to Naming Ionic and Covalent Compounds

An ability to dissolve in polar solvents such as water, whose partially charged nature leads to an attraction to the oppositely charged ions in the lattice. And there are a lot of ionic compounds which are insoluble in water, of course. To name this acid, the ending -ite is switched to -ous.

In the case of molecules, dots are placed between two atoms to depict covalent bondswhere two dots a shared pair of electrons denote a single covalent bond. As a result, the electrons tend to spend more time at one end of the bond than the other. Sharing Is Caring 10 minutes Lesson Reflection: If you need some more background on metallic bondingyou could follow this link.

Solubility of a low melting point solid or a liquid in water without it reacting suggests a small molecule capable of hydrogen bonding - or, at least, a small very polar molecule. One end of the bond is relatively positive less attraction for electronsand one end of the bond is relatively negative more attraction for electrons.

You can see that there are planes or layers of atoms. In short, the existence of the chemical bonds accounts for the richness of chemistry that reaches far beyond just those building blocks.

These Bucky balls each contain about sixty carbon atoms, some contain 60, some 70, some Explain how covalent bonding can result in both network and molecular materials, in both elements and compounds, and in polyatomic ions.

This type of error seems common with 9th grade students and is attributed to a lack of concentration and attention because the student really had mastered the content! That is what gives graphite its slippery quality.

Draw molecular, structural, electron dot formulas and orbital diagrams for molecules Identification of orbital hybridization may be included at the State and National level.

When this occurs, each atom has exactly the same attraction for the electrons that make up the covalent bond, and therefore the electrons are perfectly shared.

If it is a gas, liquid or low melting point solid then you are talking about a simple molecular substance.

Ch. 6: Chemical Bonding

Overall, this two week activity was a very powerful learning experience for the students — and for myself as their teacher — and I hope to see the skills they acquired through this activity transferred to their final lab report of the year in our next unit.

Identify which 2 of the following substances will conduct electricity, and explain why. In larger molecules with multiple covalent bondseach bond will have either no dipole or a dipole with varying degrees of partial charge. Remind students that covalent bonds only occur between two non-metals!

In panel B, three H2O molecules interact favorably, forming a dipole-dipole interaction between the partial charges. The lab reports showed an exceptional understanding of the subject matter, with students going well above and beyond the requirements almost across the board — and the test students took following the lab in which they analyzed hypothetical results showed equal understanding and analytical ability.

You will not have to learn these yet. Write its name and formula. Hit Or Miss Mastery! If ionic bonding and covalent bonding sit at the extreme ends of a bonding spectrum, how do we know where any particular compound sits on that spectrum? The answer is a simple one.

Bonding With Your Students 1 minutes The video clip provides an introduction and rationale for this lesson reviewing types of chemical bonds. Such fixed ratio combinations of those elements are known as compounds. This leaves each oxygen atom with the ability, actually, the necessity to bond to other atoms.

The steel in this compound is iron. Conduction of electricity Conduction of electricity in the solid state suggests delocalised electrons, and therefore either a metal or graphite or graphene if your syllabus mentions it.To name a covalent compound, you need the molecular formula, Steps to Naming Covalent Compounds.

First, identify the elements present. Second, look at the subscript of each element to determine which prefix to use. (If an element does not have a prefix, assume that the subscript is “1.” Recall that ionic compounds consist of a. UC Irvine FOCUS!

5 E Lesson Plan Title: Covalent and Ionic Bonding – Lewis Structures Lab Grade Level and Course: 8th grade Physical Science, 10th and 11th Chemistry Materials: covalent or metallic bonds or by exchanging electrons to form ionic bonds.

e. Write 3 questions about naming/writing formulas for ionic compounds that Mr. Klotz could use on the exam Write 3 questions about naming/writing formulas for covalent compounds that Mr.

Klotz could use on the exam. Title: Metallic Bonding Ionic and Covalent Compounds Review Practice Names and Formula Lab Ionic and Covalent Compounds.

Forming and Naming Ionic Compounds Lab. Problem. Forming and Naming Ionic Compounds. Introduction. Intent. Since this lab is an introduction to writing formulas, the key positive or negative ions are listed on the table in the Report Sheet.

Prelab Discussion. It's a good discovery-type lab and gives them a little bit less you've already covered metals, ionic, and covalent compounds, have the students determine which category each fits you're feeling like giving them a tough time, don't give them the microscope or conductivity tester.

Formulas and Names of Simple Covalent Compounds. Always write/name the element with more metallic character first. Metallic character increases going from right to .
