Summary of the Movie Gladiator essays

Summary of the Movie Gladiator essays The movie that I chose to do my movie critique on was Gladiator. It was an enjoyable movie to watch. The director Ridley Scott directs a film by David Franzoni, to depict exactly what it was to be a gladiator and the adventure that they went through. From the infamous fights that took place in the Roman Coluseum, to the dramatic feeling that overcame Maximus (Russell Crowe) as his family was killed through the treacherous actions of his rival Commodus (Joaquin Phoenix). The movie Gladiator begins with the battle with Romanian Army under the leadership of Emperor Marcus Aurelius against the Barbarian Tribe of Germania. This scene showed many striking points. For instance take the scene and where it takes place. In many scenes of the movie the armies are dressed in traditional armor. The armor that they wore contained great detail. The roaring sounds from the crowd of soldiers being excited because they are so eager to go into battle to fight helps the viewer feel the excitement that is taking place in the movie. The music helps the viewer get feel like they are standing in the middle of the battle while it was taking place. The director used many sound effects that helped bring the movie to life, such as the clinking of the swords during the fight and the sound of arrows flying through the air. As the plot continues the Romanians win the battle and return home all the while Emperor Marcus Aurelius becomes ill and is on his last days. Knowing this he privately tells Maximus that he will be the next emperor in the event of his death. Before the announcement was made Marcus Aurelius was killed by his own son to prevent Maximus from being the next emperor. During this scene you can see that the lighting played a significant role because there were no electricity back then and lanterns and candles were the source of lighting. The lighting from the candles it shows just the faces of Marcus Aurelius ad Maximus as they discuss Maximus ta...

Element Group 15 - Nitrogen Family Facts

Element Group 15 - Nitrogen Family Facts The nitrogen family is element group 15 of the periodic table. Nitrogen family elements share a similar electron configuration pattern and follow predictable trends in their chemical properties. Also Known As: Elements belonging to this group are also known as pnictogens, at term derived from the Greek word pnigein, which means to choke. This refers to the choking property of nitrogen gas (as opposed to air, which contains oxygen as well as nitrogen). One way of remembering the identity of the pnictogen group is to remember the word starts with the symbols of two of its elements (P for phosphorus and N for nitrogen). The element family may also be termed pentels, which refers both to the elements formerly belonging to element group V and their characteristic of having 5 valence electrons. List of Elements in the Nitrogen Family The nitrogen family consists of five elements, which start with nitrogen on the periodic table and move down the group or column: nitrogenphosphorusarsenicantimonybismuth Its likely element 115, moscovium, also exhibits traits of the nitrogen family. Nitrogen Family Facts Here are some facts about the nitrogen family: Nitrogen family elements consists of atoms having 5 electrons in their outer energy level. Two of the electrons are in the s subshell, with 3 unpaired electrons in the ​p subshell.As you move down the nitrogen family: atomic radius increases, ionic radius increases, ionization energy decreases, and electronegativity decreases.Nitrogen family elements often form covalent compounds, usually with the oxidation numbers 3 or 5.Nitrogen and phosphorus are nonmetals. Arsenic and antimony are metalloids. Bismuth is a metal.Except for nitrogen, the elements are solid at room temperature.Element density increases moving down the family.Except for nitrogen and bismuth, the elements exist in two or more allotropic forms.Nitrogen family elements display a wide range of physical and chemical properties. Their compounds may be transparent, either diamagnetic or paramagnetic at room temperature, and may conduct electricity when heated. Because the atoms form double or triple bonds, the compou nds tend to be stable and potentially toxic. Element facts include crystal data for the most common allotropes and data for white phosphorus. Uses of Nitrogen Family Elements Two of the elements, nitrogen and phosphorus, are essential for life.Most of the Earths atmosphere consists of nitrogen gas, N2. Diatomic pnictogen molecules like this may be called pnictides. Because of their valence, pnictide atoms are connected by a covalent triple bond.Phosphorus is used in matches, fireworks, and fertilizer. Its also used to make phosphoric acid.Arsenic is toxic. It has been used as a poison and as a rodenticide.Antimony finds use in alloys.Bismuth is used in medications, paint, and as a catalyst.
