    Water has many unique properties that make life possible on Earth. One property is cohesion. The cohesion property is properly defined as the binding of water molecules by hydrogen bonds. Water has this property as a result of the chemical bonding between water. Cohesion of the strong hydrogen bonds allows the water molecules to stick together‚ almost as a unit of one. A force exerted on one of the molecules will be exerted on all of the adjacent molecules as a result of cohesion. Cohesion‚ often

    Subject Content Most of the objectives specified in this section relate to Knowledge with Understanding‚ although some indication has been given as to where the skills of Handling Information and Solving Problems may be developed. Teachers are reminded that‚ in the written papers‚ 40% of the marks are allocated to these higher ’thinking’ skills. In almost every section‚ students should therefore be given practice at dealing with unfamiliar situations so that these higher thinking skills can be developed

    shell shape will be more complex if you have more electrons in that element. Electrons play a huge role in chemical bonds. An electron being transferred from one atom to another is called electrovalent bonding‚ which is also known as ionic bonding. Another type of bonding is called covalent bonding‚ which is where electrons are equally shared between two or more atoms in a cloud. John Joseph Thomson‚ also known as J.J Thomson‚ discovered the electron in 1897. He was a physics professor at Cambridge

    Unit 1 Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand

    INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest
