Molecule Polarity PhET Lab A study of electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from

Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial

The Grignard Synthesis of Triphenylmethanol Abstract: Grignard synthesis of triphenylmethanol was achieved by use of the Grignard reagent phenyl magesium brominde. The organometallic grignard reagent was synthesized by use of a reflux apparatus recrystallization techniques. Once synthesized it was used in a Grignard reaction that involved nucleophilic addition to a carbonyl in order to make triphenylmethanol. The final product was solidified and recrystallized and spectral data was

and SO42- is K2SO4. ii) The formula of the simplest possible compound containing only C and I atoms is CI4. iii) K2SO4 was formed by ionic bonding and has overall regular/repeated crystal structure‚ it has a melting point of over 1000oc‚ ionic compounds like K2SO4 are also often soluble in water. CI4‚ in contrast‚ was formed by covalent bonding and has an irregular crystal structure. Molecular compounds have lower melting points and CI4 has a melting point of less than 200oc and is unlikely

molecules is that atoms are the smallest units of matter and can not be divided by chemical means. Molecules are made up of atoms of the same kind that are together in a group. The difference between covalent bonds and ionic bonds are that covalent bonds have 2 atoms sharing the same electron. Ionic bonds occur when an atom takes one electron away from another atom. 2. Adhesion and Cohesion differ because adhesion is when 2 substance of the same kind are joined together. Cohesion is when 2 substances

proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic hydrogens is replaced by a hydroxyl group. Serine is one of two hydroxyl amino acids. Both are commonly considered to by hydrophilic due to the hydrogen bonding capacity of the hydroxyl group. Threonine‚ an essential amino acid‚ is a hydrophilic molecule. Threonine is an other hydroxyl-containing amino acid. It differs from serine by having a methyl substituent in place of one of the hydrogens on the β carbon

3.1.1 Identify that matter is made of particles that are continuously moving and interacting The particle theory states that all matter is made up of tiny particles and they are constantly moving/continual state of motion. 1.1.2 Identify the difference between elements‚ compounds and mixtures in terms of particle theory Elements are simplest form substance meaning cannot be decomposed further physically or chemically. They are made up of same type of atoms only e.g. helium‚ oxygen. Compounds
