Molecule

Molecules are a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central atom. We analyzed the information that we discovered on the website that was given to us in the lab. We found that there are several types of bond pairs. Some types are linear, trigonal, tetrahedral, trigonal bipyramidal and octahedral. We also…

In the chemistry universe we have many different tools to differentiate and to help identify a substance. The smallest particle of matter is the atom. An atom has the same chemical particles as a whole sample of the element. Everything in the world is made up of these tiny particles called atoms. Growing on our knowledge of the atom, if you combine two atoms chemically you produce a compound. The two different classifications of compounds include organic compounds or those that contain carbon…

Everything in the universe has one thing in common. Whether it be a piece of dust or the hubble space telescope, everything is made up of molecules. A molecule is a group of atoms bonded together and is basically the smallest fundamental unit of a chemical compound. When the temperature of these molecules heats up it creates kinetic energy which makes these molecules speed up and bounce against each other really fast. The temperature of a substance can be measured in one of three ways; Kelvin,…

Electron Motion Control and Imaging M. Th. Hassan Electron motion in atomic systems, which happens on timescales of attoseconds (10-18s), is at the heart of all phenomena in nature. For instance, the motion of electrons in the chemical bonds determines the structure change in the molecules. Therefore, controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, recording snapshots of the electron motion will provide real-time access to all…

Since the NaCl compound has a molecular weight of 58.44 g/mol and water has a molecular mass of 18.01 g/mol, this shows that NaCl is a bigger molecule. The chickpeas surface undergoes osmosis, allowing for water and/or salt to move from a higher concentration in the surroundings to a lower concentration into the chickpea. Due to the size of the salt molecule, the chickpea will take in less NaCl molecules compared to water molecules to occupy the same space in the chickpea. Figure 2 is a graph of…

Free radicals are molecules that have at least one unpaired electron. They are typically very reactive, due to their odd number of electrons. These molecules tend to try and gain or lose electrons so their highest energy levels can be filled. They will bond with other compounds in the body, sometimes combining with them, or even taking parts of intact molecules, resulting in even more free radicals (Walling). Free radicals can be formed by natural body processes, such as metabolism. They…

Introduction Stereochemistry alludes to the science that reviews the properties of stereoisomers. It can likewise be characterized as the branch of chemistry concerned about the three-dimensional course of action of particles and atoms and the impact of this on concoction responses. A critical branch of stereochemistry is the investigation of chiral atoms. Stereochemistry is otherwise called 3D science in light of the fact that the prefix "stereo-" signifies "three-dimensionality". The primary…

think that. How does this make you feel? Normal, I do not really feel bad for that, technically nothing changes. In other words, I just know more about something that was all the time there. If you could touch something, what would you touch? Water, if for instance the atoms repulsion affect the textures of the objects, I really curios which is the real texture of the water. How do you think it would feel? I think it will feel similar, but with more density. This could be similar like…

carry out its job and that determines its functions and properties. Structure of water Water the molecule In a water molecule, there is one oxygen that has six valence electrons in its outer shell and acts as the central atom. Two of these electrons is shared with the two hydrogen atoms which have one valance electron each in their outer shell giving a chemical formula of H2O. This shared pair helps to fill…

with the neighbouring molecule for them to bond. A covalent bond only occurs between two non-metals, the molecules share electrons to achieve full valence shells for the molecule to be stable. In the case of water the two hydrogens and one oxygen share electrons to get the hydrogen molecules with two electrons in their outer shells and…
