Nonpolar Covalent: This type of bond occurs when there is equal, or near equal sharing (between the two atoms) of the electrons in the bond. Molecules such as Cl2, H2 and F2 are the usual examples. Textbooks typically use a maximum difference of 0.0 - 0.4 to indicate nonpolar covalent bonds.
Polar Covalent: This type of bond occurs when there is unequal sharing of the electrons between the atoms. Molecules such as NH3 and H2O are the usual examples. The typical rule is that bonds with an electronegativity difference than between 0.5 and 1.7 are considered polar.
III. Ionic: This type of bond occurs when there is complete transfer of the electrons in the bond. This bond does not contain atoms at all, it consists of two ions. Substances such as NaCl and MgCl2 are common examples. Generally, electronegativity differences of 1.8 or greater create ionic bonds. Hope this is of help.

It is physical. The wire changes shape, but it is still made of the same materials.
What are the two types of microscopes and explain one differences?
The to types of microscope are as following : 1. Simple microscope 2. compound microscope differences between these both is as following: simple microscope has one Len but compound microscope has two Len.
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
Sodium chloride is a compound explain?
A compound is formed from 2 or more chemical elements linked by chemical bonds; and sodium chloride has sodium and chlorine linked by an ionic bond. And sodium chloride (NaCl) is a chemical compound.
Can you explain what halogenation is?
The process of halogenation is a chemical reaction between a compound, usually an organic compound and a halogen. An example of halogenation is fluorination or chlorination.

compound) is a pure chemical substance consisting of two or more different chemical elements[1
Is aluminium a mixture or a compound or an element Explain the question?
Aluminium is a chemical element because all atoms are identical.
Explain why Fluorine is the most active non-metal and Francium is the most active metal?
Francium is the most electropositive chemical element and has the lowest electronegativity; for the fluorine the situation is exactly inverse.
Why is aluminum fluoride ionic and aluminum iodide is covalent?
Aluminium iodide is covalent because the electron pair is easily dragged away from the iodide ion. On the other hand, aluminium fluoride is ionic because the aluminium ion can't polarise the small fluoride ion sufficiently to form a covalent bond.
When titanium bonds with oxygen the ionic compound that forms has the chemical formula Ti2O3 and consists of Ti3 ions and O2- ions Explain why the compound has this chemical formula?
Well when oxygen is in ion form, it generally has a 2- charge on it so for ionic you write them and criss-cross charges and then it becomes Ti2O3.

The most reactive metal in group 1 of the periodic table?
Probable lanthanum.The chemical reactivity (and electronegativity) are very similar for lanthanoids. This explain the difficulties of identification and separation.
