1. Describe the difference between a mixture and a compound.
The difference between a mixture and a compound is that a mixture is a substance made by mixing other substances together. Most of the time two or more substances that are chemically united and they do not exist in fixed proportions of each other. Unlike a compound a mixture can be physically separated into pure compounds or elements. For example a cake is made up of different substances that are mixed together that are separated.
A compound on the other hand is just the opposite of ...view middle of the document...

Therefore in order to tell if a pure substance is a compound or element, you simply need to know if whether the substance is the element, made up of two or more different elements that can be observed by seeing the formula. The other option is to know if the substance is a compound by testing the thing and seeing what elements make up the item.
3. What is the difference between an ionic and covalent bond?
In order to know the difference between an ionic and covalent bond, we have to first understand the meaning of both bonds. Although they are somewhat similar in what they mean, they also differ. An ionic bond is a chemical link between two atoms caused by the electrostatic force between oppositely-charged ions in an ionic compound. A covalent bond Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together (Tillery, 2009).
The difference between an ionic and covalent bond are that an ionic bond is formed between two atoms. This is usually done by a metal and...

From these properties of bonds we will see that there are two fundamental types of bonds--covalent and ionic. Covalent bonding represents a situation of about equal sharing of the electrons between nuclei in the bond. Covalent bonds are formed between atoms of approximately equal

The Periodicity Of Hydrides In Groups 4 To 7

917 words - 4 pages Hydride is the name given to any hydrogen compound. There are three types of hydrides: ionic hydrides, covalent hydrides and transitional metal hydrides. Ionic hydrides consist of hydrogen and an electropositive metal. The hydrogen atoms form ionic bonds with an electropositive metal by acquiring an electron from the metal to complete its S-shell. Covalent hydrides however consist of a covalent bond between hydrogen atoms and electronegative

When chlorine gains an electron it becomes negatively charged, and then when both of the elements combine due to opposite charges, it creates sodium chloride.

763 words - 4 pages of configuration. In the process, one atom becomes positively charged and the other negatively charged. These charged atoms are called ions. Therefore the chemical bond formed is known as ionic bond, a very strong chemical bond.        Most organic compounds are covalent compounds. They are weaker or they easily yield to chemical reactions, e.g. combustion, and substitution. They have higher melting points compared with most inorganic compounds


332 words - 2 pages bonding is when a metal gives an electron(s) to a non-metal to form an ionic compound, the compound is held together by the electrostatic energy from the elements being polar after the swap of electrons. Covalent bonding is when non-metal atoms share electrons in order to have full outer shells. Sodium is in group one the alkali metals which are very reactive due to them having only one valent electron that can be easily lost in an ionic bond
