Electron configuration

Which metals produce similar flame colors (according to your naked eye)? NaCl and NaNo3 both turned the color orange. 2. What metal ions are in the unknown solutions A and B from the barrels on the vacant lot? Clearly, and in detail, explain your reasoning. The metal ions BsCl and LiCl are in the unknown solutions A and B from the barrels on the vacant lot. 3. A student performed flame tests on several unknown substances and observed that all of the flame colors were shades of red.…

is formed between one oxygen atom and two hydrogen atoms. This is because oxygen needs to gain two electrons to become like neon and hydrogen needs to gain one electron to become like helium so they share electrons for each hydrogen atom and the oxygen atom ‘consider’ that they have achieved the noble gas configuration. This covalent bond forms a bent shape in order to share the necessary electrons. Water has many unique properties, one of which has allowed life to continue to exist during the…

What is a Periodic Table and what is it used for in science and our everyday lives? On entering the chemistry laboratory at Mercer University, for Science 100 a large colorful chart displaying rows and columns of cells, was hanging over the chalkboard. I immediately felt a bit intimidated and my heart began racing. I questioned myself as to what am I about to experience? Moving closer to examine the chart, I felt as if the bright colors on the chart were generating warmth (energy) and…

electrical energy. Nevertheless, there would be no life on Earth without radiant energy. What is radiant energy? The energy of electromagnetic waves and gravitational radiation is radiant energy. Radiant energy is the result of a change in configuration of electrons. It can travel through any substance including air, liquid, glass, and space. However, matter is not necessary for transmission of radiant energy. Even in a vacuum environment, radiant energy can move. Radiant energy moves in…

atomic number is 20 and the average atomic mass is 40.078. It is very reactive and it is a silver grayish color. It's chemical symbol is Ca and it is the the second group and 4th period. It is a metal and it electronic configuration is 20 protons 20 neutrons and 20 electrons. 2 on the fist layer, 8 on the second, 8 on the third and 2 on the fourth. Calcium is a necessary mineral in everyone's body. It grows our bones and teeth and it keeps them healthy. According to lenn tech, 99%…

circuit solely using operational amplifiers because this way we had better chance to find and amplify the desired signal for the first time. We chose TL071 amplifiers because of the high gain and low noise (CMRR) characteristics. This circuit configuration is also called instrumentation amplifier. The first stage for the instrumentation amplifier is the input stage or buffer. The second stage is the differential gain amplifier. The input stage gives no common mode gain (no common mode noise)…

An example would be radiotherapy which works on radiation’s ability to kill living cells. When radiation, such as beta radiation enter a living cell it donates energy to nearby atoms and molecules which allows electrons other than those on the outer orbit to be released. This makes the atoms very unstable (Radicals) and are so reactive they last only milliseconds. Radicals react with nearby molecules in a limited amount of time, resulting in breakage of chemical…

Several configurations of it were formed in the solution due to the rotations of alkyl chain, forms of imidazole ring and the planar configurations of thioureido ring. Replacing side chain –CH2- with –S- result in the formation of Thioburimamide with improved the activity and by adding 4-methyl on the imidazole ring result in the…

In site 1, the electron density is for the medium chain fatty acids although in their respective complexes the density is weaker and broken for the longer fatty acids. The location of site 2 is between the sub-domains IA and IIA. Site 2 is made of the fatty acid binding…

radioactive drugs inserted into the patient through injection. Before the uses of nuclear chemistry in medicine are discussed, it is vital to study the chemistry of nuclear and radioactivity. A nuclide consists of protons and neutrons in any configuration. Most nuclides are unstable and spontaneously release energy. Sometime subatomic particles are also released in order to reach the level of more stability. This process of attempt to go from unstable to stable state is the key for…
