The substances were identified according to their properties. Paraffin wax was identified as a non-polar covalent solid‚ sucrose is a polar covalent‚ sodium chloride was acknowledged as an ionic solid‚ tin is a metallic solid‚ sand is a network covalent‚ unknown#1 is a non-polar covalent solid‚ unknown#2 is an ionic solid‚ and unknown#3 is a polar covalent solid. These conclusions were made based on their physical and chemical properties. Introduction Solid substances are classified by the types

the bonds are classified by the way in which electrons are distributed within the bonds. Ionic and Covalent Bonds We will be studying two types of chemical bonds in this module: ionic bonds and covalent bonds. Atoms can gain or lose electrons to become charged ions. They form ionic bonds‚ a chemical bond that results from electrostatic attraction between positive and negative ions. This means that in an ionic bond‚ electrons are given up by one atom and gained by another atom‚ and then those atoms

INTRODUCTION TO CHEMICAL BONDS CHEMICAL BOND Definition: A chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more

Three Greek Orders of Architecture Greek architecture is broken down into three orders. These orders were determined by the way that the top or capital of each column was sculpted. The first order was called the Doric Order. This was the most simple of the three. It was only meant for sturdiness‚ not for beauty. The second order was called the Ionic order. They had capitals sculpted like spiraling scrolls. They too were not that beautiful‚ but very sturdy. The third was the Corinthian Order. Ta the

and melting point. Some substances came very close to passing all the tests‚ but only one substance was able to pass all of them. I recommend using sodium carbonate as your substance. Of all the substances‚ only two were covalent and two were ionic. The ionic substances‚ sodium chloride‚ sodium carbonate‚ and salicylic acid‚ came close to the description you requested. The covalent substances‚ sucrose and salicylic acid‚ did not match the descriptions. The best substance would definitely be sodium
