PPT-IONS! How they are formed

Valence Electrons Valence Electrons of an atom are the electrons that are in the outermost s and p sub shells ONLY S AND P To determine how many electrons are in your valence shell look at where your element is on the periodic table. brPage 1br F57577lici tat ions F57577lici tat ions F57577lici tat ions F57577lici tat ions F57577lici tat ions F57577lici tat ions F57577lici tat ions F57577lici tat ions - To be able to explain how mountains are formed . Plate Tectonics . The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle) called tectonic plates. . These plates are in constant motion travelling at a few centimetres per year. This is called continental drift..

The hydraulic pressure rips away sections of weakened rock.. Jasper, . Zac. , Choon Wei and . allison. How oxbow lakes are formed. An Oxbow Lake occurs when the meanders become more sinuous and over lap each other and the river brakes through causing a new channel to form. . How elements become charged. How elements become charged. ION – A charged atom. All elements on the periodic table are NEUTRAL because they have the same number of . protons (+) and electrons (-). What are we testing to find?. This test is to confirm the presence of sulphate ions.. Sulphate ions are negatively charged (SO. 4. 2-. ) therefore they are anions.. How do we do the test?. Place the sample solution in a test tube.. Types of bonds. Ionic bonding. results from electrostatic attractions among ions, which are formed by the . transfer. of one or more electrons from one atom to another..
