The peaks on the first ionization energy line was labelled. The troughs on the first ionization energy line was labelled. Discussion: The elements that are on the peak of the AR graph are hydrogen‚ lithium‚ sodium‚ aluminum‚ potassium‚ and gallium. The group name for the elements of hydrogen‚ lithium‚ sodium‚ and potassium is called the Alkali Metals and it is the first group on the Periodic table. The group name for the elements of aluminum and gallium is called the Boron group and it is located

Bipolar Disorder Everyone has ups and downs in their mood; such as happiness‚ sadness‚ and anger that are normal emotions and an essential part of everyday life. In contrast‚ Bipolar Disorder is a medical condition in which people have mood swings out of proportion‚ or totally unrelated‚ to things going on in their lives. These swings affect thoughts‚ feelings‚ physical health‚ behavior‚ and functioning. Those who have children know it is rough enough at times to keep one’s composure‚ but could

replacement reaction of lithium Observations Test tube was hot after reaction; exothermic reaction took place; lithium was not malleable; when lithium was added to diH2O it popped and fizzled; splint got brighter when added to test tube; solution turned pink when phenolphthalein was added. Reactants: Li and H2O Products: H2 and LiOH Balanced chemical equation 2Li + 2H2O 2LiOH + H2 Table 8.5- Single replacement reaction of potassium Observations Lithium was malleable; splint

Bipolar disorder is one of the oldest known illnesses. Extensive research reveals that there was some mention of the symptoms in early medical records‚ which date back to the 1600’s. Bipolar was first noticed as far back as the second century. Aretaeus of Cappadocia (a city in ancient Turkey) first recognized some symptoms of mania and depression‚ and felt they could be linked to each other. Aretaeus’s findings went unnoticed and unsubstantiated until 1650‚ when a scientist named Richard Burton wrote

Chemistry Batteries [Chemistry HSC Course-1] What is an Anode? An anode is the negatively charged electrode of an electrical device but in this a primary cell‚ that supplies current. What is a Cathode? A cathode is the positively charged electrode of an electrical device which in this case is a primary cell‚ that supplies current. What is Current? A flow of current which results from the ordered directional movement of electrically charged particles. A current is the rate of flow of charge

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

Jaycar Electronics Reference Data Sheet: BATTPRIM.PDF (1) PRIMARY CELLS & BATTERIES Many portable electrical and electronic devices are designed to be powered from batteries and in a lot of cases‚ from primary or non-rechargeable batteries. This is the familiar kind of battery which has a fixed amount of energy stored in it during manufacture‚ and once that energy has been used up the battery is simply thrown away and replaced. There are many different types of primary battery now available
