properties are properties that can be measured and seen in an object. An example of a physical property of an object would be the color‚ mass‚ solubility‚ volume‚ or the polarity of an object. A physical property can change the appearance of an object‚ but that does not mean that the chemical composition has to change. The chemical composition can remain the same. Physical properties are separated into two different categories. They are separated in to intrinsic properties and extrinsic properties

Topic 4 - Bonding 4.1 Ionic bonds 4.1.1 Ionic bond: +ve (cations) and -ve (anions) ions are attracted to each other and form a continuous ionic lattice 4.1.2 Group 1 metals form +1 ions‚ group 2 metals form +2 ions‚ metals in group 3 form +3 ions . Examples : Li+‚ Mg2+‚ Al3+. Greater ease of ionisation Li->Cs is due to the increased electron shielding of the nuclear attraction caused by additional inner shells of electrons. The easier atoms are to ionise‚ the more reactive they

Doe 07 Polarity Management Dr. Polarity Management Polarity Management is by definition a "problem" or an issue that requires a solution. The goal of a problem is to find a fix to the current situation and move forward to a new reality without being required to ever look back. However‚ a "polarity" is an issue that needs to be addressed‚ but the "solution" is not one that can survive independently and will actually still require support from the original issue. Polarity Management can

Elements and compounds are a result of the actions of the valence electrons. There are three types of bonds that I have learned about in the bonding comparison lab. These bonds include ionic‚ polar covalent‚ and non-polar covalent. Each of these bonds and the element compounds connected to them has individual solubility‚ conductivity‚ melting point‚ and volatility levels. The three element compounds that will follow are sodium chloride‚ sucrose‚ and p-dichlorobenzene. Sodium chloride is an ionic
